Here is each club's Arizona Fall League sleeper prospect

Action in the Arizona Fall League kicks off this Saturday with a full slate of games, starting with the Glendale Desert Dogs hosting the Salt River Rafters at 12:30 p.m. (local time 3:30 p.m. ET).

While a lot of attention is understandably given to the high-profile prospects -- the late additions of Sebastian Walcott, Aidan Miller and Angeibel Gomez created some fun Top 100 buzz -- the Fall League also provides the opportunity for some lesser-known guys to show what they can do against good competition, with all 30 Major League organizations watching.

Here is an under-the-radar Fall Leaguer from each organization. All 30 are currently outside their system’s Top 30 Prospects list, but a strong AFL showing could change that.

AMERICAN LEAGUE EAST

Blue Jays: Aaron Parker, C
The 2024 sixth-rounder ranked third in the Blue Jays system with 19 homers over 87 games for Double-A New Hampshire this season, and that total was also tied for third-most among Double-A backstops. While Parker packed on the power in ‘26, he did so at the expense of contact with his strikeout rate climbing from 19.6 percent at High-A last year to 32.3 percent this summer, and that could be a point of emphasis in the desert. He also sprinkled in three late appearances in left field to add some versatility before his AFL time.

Orioles: Patrick Reilly, RHP
A fifth-round pick by the Pirates in 2023, Reilly went to the Orioles for Billy Cook at the 2024 Trade Deadline. At one point, he was as high as No. 10 on the O’s Top 30, but after needing Tommy John surgery three starts into the 2025 season, he tumbled off the list. He made it back for 53 innings this year and his stuff -- a fastball up to 97 mph, a slider and a cutter -- missed plenty of bats (11.9 K/9). Command has never been his forte, but if he’s around the zone this fall, he could be one of the better arms in the league.

Rays: Yereny Teus, LHP
Teus doesn’t cut a huge figure on the mound at 5-foot-10, but he certainly put up big-time numbers in his age-22 season for Single-A Charleston: namely a 2.00 ERA, .122 average-against and 80 strikeouts in 54 innings of relief. His 38.1 percent K rate was 15th-best among 1,382 Minor Leaguers with at least 50 frames this season. While using a 90-93 mph fastball, Teus earns his best grades on an 82-85 mph changeup and a low-80s breaking ball that both earned whiff rates at or above 60 percent, per Synergy. Fall League batters will represent a better test than their Single-A counterparts.

Red Sox: Antonio Anderson, 3B/1B
The Sox took Anderson in the third round in 2023 and signed him away from a Georgia Tech commitment with a $1.5 million bonus. He’s dwelled in the lower Minors ever since and hadn’t been an above-average for a full season until 2026, when he finished with a .273/.373/.453 line, nine homers and 113 wRC+ in 85 games for High-A Greenville. A switch-hitter, Anderson was more productive from the right side this season, but overall, it was most promising that he raised his High-A contact rate from 65.6 percent in ‘25 to 71.5 this summer.

Yankees: Antonio Gomez, RHP
Gomez appeared on a Yankees preseason Top 30 list as a catcher as recently as 2022, when he checked in at No. 19. But he never cracked higher than Double-A as a backstop and moved to pitching -- no shock for someone who used to have 70 grades for arm strength behind the dish. Gomez only has 10 Single-A appearances on his resume to this point, but touched 100.7 mph with his four-seamer on Aug. 8 and showed a short upper-80s slider during his time at Single-A -- two pitches that could grab more attention in the Valley.

AMERICAN LEAGUE CENTRAL

Guardians: Aidan Major, RHP
The 2024 fifth-rounder missed the entire 2025 season due to Tommy John recovery and rehab and got back on the mound this spring with Single-A Hill City, only to get struck in the head by a comebacker in a scary scene on May 26. He returned to the club two months later, and was promoted to High-A Lake County after three more starts, finishing the regular season with a 4.55 ERA and 57 strikeouts in 63⅓ innings. He sits 91-93 mph with his fastball and uses a low-80s slider, a mid-80s changeup and an upper-70s curveball to get whiffs.

Royals: Austin Charles, SS
Kansas City has been high on Charles’ potential as a big-bodied infielder (he’s 6-foot-5) since signing him for $429,500 as a 20th-rounder back in 2022. While he was limited to only 45 games with High-A Quad Cities by a core injury that kept him out for three months, he was productive with a .285/.353/.491 line, seven homers, 10 steals and a 115 wRC+ in that time. His 75.3 percent contact rate in the Midwest League was the highest of his career, a promising sign given he has at least above-average power potential.

Tigers: Maddox Long, RHP
The 6-foot-5 right-hander opened the season with the Washington WildThings in the Frontier League before the Tigers picked him up in June. He sported a 3.74 ERA and a 1.16 WHIP with 44 strikeouts in 33⅔ innings across the Florida Complex League, Single-A Lakeland and High-A West Michigan and now heads to Scottsdale for his fifth team of ‘26. The 25-year-old uses a 82-85 mph high-spin slider as a primary pitch -- understandable since it had a 40 percent whiff rate in full-season ball -- and backs that up with a pair of low-90s fastballs, a cutter and a changeup.

Twins: Jacob McCombs, OF
After a strong sophomore-eligible season at UC-Irvine, McCombs went to the Twins in the seventh round of the 2025 Draft. He’s a solid left-handed hitter who can be aggressive at the plate, making a ton of contact. There’s some raw pop for him to tap into and he’s looking to make up for some lost at-bats, playing just 67 games with High-A Cedar Rapids during his first full season of pro ball. He’s capable of playing all three outfield spots.

White Sox: Garrett Wright, RHP
Wright signed with the White Sox as a 20th-round pick out of TCU in 2023 but only managed 16⅔ innings over the next two seasons combined. He climbed three levels in ‘26 and finished with a 4.20 ERA, .181 average-against and 77 strikeouts across 55⅔ innings between Single-A, High-A and Double-A. Now Wright heads to Glendale to close out his 40-man roster-decision year. The 6-foot-2 righty sits 95-98 mph with his fastball and gets a ton of whiffs with his 87-90 slider from an over-the-top delivery.

AMERICAN LEAGUE WEST

Angels: Peyton Olejnik, RHP
Olejnik has the chance to stand out for the Mesa Solar Sox, and it’s not just because he’s 6-foot-11. The right-hander was on the back end of the Angels’ Top 30 at the start of the season, but got nudged off as he posted a 4.47 ERA in 106 2/3 IP with High-A Tri-City. He still missed bats (9.4 K/9), but as a guy without wow stuff, he needs to cut down on his walks and command his stuff within the zone better so he doesn’t get squared up as much (8.3 BB/9 in 2026).

Astros: Juan Bello, RHP
Bello signed with the Cubs for just $10,000 in 2022 and was coming off a solid 2024 full-season debut when he was sent to the Astros in January 2025 for Ryan Pressly. Bello has an intriguing four-pitch mix led by a curve that can really miss bats, but he hasn’t thrown a competitive pitch since July 2025 because of an elbow injury that required Tommy John surgery. There might be some rust to shake off, but this stint could help the 22-year-old get ready for a jump to Double-A in 2027.

A’s: Jay Dill, RHP
Dill served as Troy University’s closer in 2025 and showed off enough power stuff for the A’s to take a no-risk $100,000 flier on him in Round 18 of the Draft that July. He pitched his way from Single-A Stockton to Double-A Midland in his first full season, and the hard-throwing reliever used his power repertoire to strike out 10.7 per nine with a 30 percent overall miss rate. Whether he can throw strikes consistently enough (5.6 BB/9) will be the key to him finding a big league bullpen role in the future.

Mariners: Ty Cummings, RHP
A reliever at Campbell University in 2023, Cummings was drafted in Round 7 in 2023 and given a chance to start by the Mariners. He had an encouraging first full season in High-A Everett’s rotation in 2024, then was shipped to the Rays as the player to be named later in the Randy Arozarena deal. He reached Triple-A in 2025, albeit without missing many bats, then was on the move again … back to the Mariners this April. Back in the bullpen, the results weren’t there post-trade (6.04 ERA with Double-A Arkansas), but he was sitting 95 mph with his heater for most of the year with an intriguing east-west profile.

Rangers: Jesus Gamez, RHP
Gamez could be one of the most volatile arms in the desert this year. He struck out 69 batters over 43⅓ innings at High-A Hub City this summer but walked more than a batter per frame (47) in that same span. He can get his fastball up to the upper 90s, and that does a nice job of setting up his secondaries with his slider and splitter both sporting whiff rates above 67 percent, per Synergy. He needs to find more of the zone or elicit more chase to be truly effective, but the volume of swing-and-miss makes him at least interesting.

NATIONAL LEAGUE EAST

Braves: Tyler LaPorte, RHP
At 29, LaPorte is the oldest player in the AFL this year and the oldest participant in recent memory (even older than Tim Tebow!) Initially an infielder at Southern University, LaPorte pitched in the Draft League at age 24 in 2021. That led to a four-year odyssey through the indy ball ranks, playing in both the Atlantic and Frontier Leagues before finally getting a shot in affiliated ball when the Braves signed him ahead of the 2025 season. He spent 2026 at Double-A, finishing with a 1.84 ERA, a 13.4 K/9 rate and 10 saves. He can run his fastball up to 97 and his 84-85 mph slider elicited a 47 percent miss rate this season.

Marlins: Carter Johnson, INF
Johnson was an over-slot second-round sign by the Marlins in 2024, joining the organization out of the Mississippi high school ranks for $2.8 million, $1.2 million above pick value. He really scuffled through his first full season (.536 OPS) in 2025, but started to get to some impact and reached High-A in 2026, thanks to some better swing decisions and added strength. He’ll keep working on attacking better pitches in better counts while continuing to work all over the dirt.

Mets: Peyton Prescott, RHP
Prescott touched triple digits out of the Florida State bullpen in the spring of 2025 but tore the UCL in his right elbow and needed Tommy John surgery. The Mets took him in the fifth round anyway, believing it could be a buy-low opportunity on an electric arm. Prescott finally made his organizational debut with one inning for Single-A St. Lucie, sitting between 94.5 and 96.5 mph with that four-seamer while sprinkling in cutters, sliders, changeups and curveballs over the 18-pitch outing. The slider and changeup were both whiff-heavy options as an amateur, but the biggest thing for Prescott will be just establishing a broader foundation of innings heading into his second full season.

Nationals: Jorgelys Mota, OF/3B
Nats fans might recall that Mota had the highest exit velocity (115.0 mph) and longest home run (434 feet) recorded by any Washington player during Grapefruit League play last spring. He also possesses an impressive set of wheels, giving him one of the best (if not the best) combinations of power and speed in the system. However, he played only 23 games for High-A Wilmington this summer and made contact on just 57.1 percent of his swings with the Blue Rocks, underlining the hit-tool concerns that have plagued much of his career. Mota could still be good for a number of highlights with Salt River this fall, and he’ll also continue his transition to center field, where his athleticism can flourish all the more.

Phillies: Kehden Hettiger, C/1B
The surface numbers don’t stand out for Hettiger, with a career .676 OPS and a .191/.317/.348 line over 61 games for Double-A Reading this year. But there’s raw power in his left hand swing and some of his underlying tendencies -- he doesn’t swing at pitches out of the zone and pulls the ball well in the air -- are interesting, even if he needs to work on his in-zone miss. He also grades very well in terms of his defensive metrics behind the plate and he’s still only 22 years old.

NATIONAL LEAGUE CENTRAL

Brewers: Matt Wood, C
Wood may have been a bit overshadowed by bigger names on a loaded Double-A Biloxi roster this season, but his performance was up there among the Shuckers’ best. The lefty slugger rarely expanded the zone and made a good amount of contact when he did swing, leading to a 52/71 K/BB ratio and a .398 OBP over 95 games in the Southern League. The Brewers also improved the quality of his angles off the bat, enabling him to hit a career-high 18 homers. He was left unprotected when eligible in last year’s Rule 5 Draft but could strengthen his 40-man case by carrying his momentum to the Scottsdale roster.

Cardinals: Sammy Hernandez, C/1B
Hernandez began the year as High-A Peoria’s No. 2 catcher behind phenom Rainiel Rodriguez, but after Rodriguez’s promotion to Double-A Springfield, the 5-foot-9 backstop took on a more central role and flourished, finishing with a .279/.411/.529 line, 11 homers and 21 steals across 65 games in the Midwest League. His 140 wRC+ was third-best in the system behind Rodriguez’s 150 and Miguel Hernández’s 146. An extreme pull hitter from the right side, Hernandez cut down on some of his swing aggression and nearly doubled his previous career homer high of six in the process.

Cubs: Kade Snell, OF
Snell began his college career as a left-handed pitcher at Auburn, but after redshirting because of injuries in 2021, he transferred to Wallace-Dothan Community College in Alabama and was the national junior college player of the year as a two-way guy in 2023. After transferring to Alabama and serving in both roles the next year, he was an outfielder only in 2025, leading to him becoming an intriguing money-saving senior sign in the fifth round of that year’s Draft. A broken wrist limited him to 81 games with High-A South Bend, but he offers an intriguing combination of feel for the barrel and swing decisions to go along with sneaky pop, the ability to steal a bag and play all three outfield spots, though he’s likely best suited for left.

Pirates: Zander Mueth, RHP
The Pirates went over slot to sign the projectable Mueth out of the Illinois high school ranks for $1.8 million in the second round of the 2023 Draft. It has not gone well since an encouraging 2024 debut season and he’s yet to get past Single-A Bradenton. The 6-foot-6 right-hander's raw stuff has always been electric -- he was up to 99 mph with his heater this year -- but he’s struggled with his command both in the zone (9.2 BB/9 this season) and out of it (8.7 BB/9). The Pirates are hoping ignite something by having him come out of the bullpen this fall without telling him when he’s pitching until the day of. He’s often been guilty of trying to do too much off the field and they want him to just show up and let his stuff play.

Reds: Victor Diaz, RHP
Diaz joined the Reds as a non-drafted free agent out of Seminole State Junior College in August 2024 and had a fairly nondescript first full season of pro ball in 2025. Things clicked a bit more pitching out of High-A Dayton’s bullpen this year, striking out 13.3 per nine (albeit with a 6.5 BB/9 rate) and posting a 3.33 ERA to earn a bump up to Double-A. His fastball, which tops out at 99 mph, missed bats at a 30 percent rate in 2026.

NATIONAL LEAGUE WEST

D-backs: Joe Ariola, LHP 
The 6-foot-2 left-hander struck out 45.7 percent of his batters faced over 34⅔ innings across the Arizona Complex League, Single-A, High-A and Double-A this season, giving him the highest K rate among the 2,402 Minor Leaguers who pitched at least 30 frames in 2026. As if that wasn’t impressive enough, the 2025 seventh-rounder out of Wake Forest also finished with a 1.56 ERA and a 1.04 WHIP over 21 appearances. Ariola throws a 93-96 mph fastball from a high release that can make hitters uncomfortable, and his 79-81 mph curveball gets plus-plus whiff rates off of that. He can also mix in a slider and a changeup to keep hitters guessing, though he doesn’t need them as much in a relief role.

Dodgers: Sam Horn, RHP
Horn might be the most intriguing guy on this list, which is kind of amazing since he’s yet to throw a pro pitch and amassed just 15 innings over two seasons at Missouri. Tommy John surgery knocked out his 2024 season and most of his career as Mizzou’s quarterback also got erased by injury, including a broken tibia suffered on the one play he ran under center for the Tigers after signing with Los Angeles for nearly $500,000 in the 17th round of the 2025 Draft. It will be everyone’s first pro look at Horn, his fastball (up to 98 mph in 2025) and his 82-86 mph sweeper.

Giants: Dalton Wentz, 2B/3B
One of two 2026 draftees in the Fall League this year, Wentz hit 18 homers and finished with an OPS over 1.000 at Wake Forest this past spring as one of the more intriguing sophomore-eligibles in the class. The Giants gave him almost $585,000 in Round 16 to add him to their robust system and he got his feet wet with 13 games for High-A Eugene. He has a power-over-hit profile and can really crush fastballs, though he’s going to have to learn to tone down his aggressiveness and handle soft stuff better while seeing time at second and third base.

Padres: Justin DeCriscio, UTIL
The 2025 10th-rounder out of NC State focused primarily on shortstop between Single-A, High-A and Double-A in his first full season but also saw time at five different positions, giving him the utility label at an early juncture in his career. Batting from the right side, DeCriscio posted solid contact rates at every stop to fuel his rise and finished with a .270/.358/.425 line, 13 homers and 22 steals over 121 games. He may project best as a hit-tool forward player who can fill multiple roles off the bench, and that’d be a solid outcome for a former senior sign who joined the organization for just $15,000.

Rockies: Jack O’Dowd, C/1B
The son of former Rockies’ GM and long-time MLB Network analyst Dan O’Dowd, it took a while for Jack O’Dowd to find a home. He hit over .300 in the Draft League in 2024, then spent a year lighting up the independent Pioneer League before the Rockies signed him as a free agent this past January. Playing most of the year at age 25, the fact he crushed Single-A California League pitching didn’t land on many radars, but people started noticing when he got bumped up to High-A after 22 games. He was on the move again to Double-A 34 games after that, and while his production certainly dipped with Hartford, he still finished the year with a .307/.383/.564 line to go along with 23 homers and 91 RBIs.
