Since the Arizona Fall League started in 1992, it has sent more than 3,000 players to the big leagues, including Hall of Famers Roy Halladay, Todd Helton, Derek Jeter and Mike Piazza. The developmental circuit, which begins its 33rd season on Oct. 6, also has produced current stars such as Ronald Acuña Jr., Mookie Betts, Aaron Judge, Nick Kurtz, Francisco Lindor, Julio Rodríguez and Corey Seager.
This year's rosters are as stacked as usual, including 11 of MLB Pipeline's Top 100 Prospects, headlined by two of the best six in shortstops Kevin McGonigle (Tigers) and Sebastian Walcott (Rangers). The last time two phenoms ranked that high played in the same AFL season was in 2011, when Bryce Harper and Mike Trout teamed up on the Scottsdale Scorpions.
Below we identify the top prospects each organization is sending to the Fall League:

AMERICAN LEAGUE EAST
Blue Jays: Josh Kasevich, SS (No. 12)
The 2022 second-rounder looked likely to debut in the Majors this year after hitting .325 over 41 games with Triple-A Buffalo last season, but a stress reaction in his lower back and a hand injury kept him from rejoining the Bisons until Aug. 15 this summer. He hit .173 and slugged just .184 in 29 games back at the Minors’ top level but still showed elite patience and contact rates. The hit tool could still be there, but he’ll need to show more impact at the plate in the desert to stop from sliding down the Jays’ Top 30.
Orioles: Enrique Bradfield Jr. OF (No. 4)
After stealing 74 bases in 2024, Bradfield was shut down twice by hamstring injuries this season and he played in just 76 games in 2025, a big reason why he’s AFL-bound. He did manage to swipe 36 bags and went 20-for-22 in August and September when fully healthy, so we could see a lot of theft in Arizona.
Rays: Aidan Smith, OF (No. 6)
Acquired from the Mariners in last year’s Randy Arozarena trade at the Deadline, Smith flashed some impressive tools in his first full season in the Tampa Bay system, and he still profiles as a potential power-speed option from the outfield. The 21-year-old struck out 31.2 percent of the time with High-A Bowling Green, however, dropping him from his ceiling as a Top 100 type. Additional at-bats in the desert could help him lock in on a better plan at the plate.
Red Sox: Luis Perales, RHP (No. 9)
Before he blew out his elbow in June 2024 and had Tommy John surgery, Perales ranked as Boston's best pitching prospect thanks to his upper-90s fastball and upper-80s splitter. Signed for just $75,000 out of Venezuela in July 2019, he touched 100 mph when he returned to the mound with two brief appearances earlier this month.
Yankees: Bryce Cunningham, RHP (No. 5)
The Yankees selected Southeastern Conference pitchers with five of their first six picks in the 2024 Draft, including Cunningham out of Vanderbilt in the second round. Featuring a mid-90s fastball and a nifty upper-80s changeup with plenty of fade and sink, he posted a 2.82 ERA, .213 opponent average and 55/19 K/BB ratio in 54 1/3 innings in High-A during his pro debut this year, though he missed two months with shoulder issues.
AMERICAN LEAGUE CENTRAL
Guardians: Daniel Espino, RHP (No. 29)
A 2019 first-rounder from a Georgia high school, Espino showcased the best all-around stuff in the Minors (fastball up to 103 mph, wipeout slider up to 93, power curveball, effective changeup) before repeated shoulder issues led to a pair of surgeries and sidelined him from April 2022 until September 2025. He touched 99 mph in a brief Triple-A outing on Sept. 20 and has pushed his heater to 102 in side sessions.
Royals: Blake Mitchell, C (No. 2/MLB No. 62)
A broken right hamate bone suffered in Spring Training limited Mitchell to only 49 games with High-A Quad Cities, and as is the case with many injuries in that area, the issue might have sapped some of his power as he hit only two homers and slugged .296 in that span. Getting to play in some friendly confines in Surprise could help as he moves farther and farther away from the initial issue. Only 21, Mitchell still has plenty of time to meet his ceiling as a slugging backstop with a rocket arm.
Tigers: Kevin McGonigle, SS (DET No. 1/MLB No. 2)
McGonigle at-bats will be must-watch in the Valley. The 2023 37th overall pick is the Minors’ best pure hitter and checks all the boxes for that designation with a disciplined approach, ability to make consistent contact and impressive impact from the left side. A career .308 hitter, McGonigle could hit above .400 in the hitter-friendly Arizona Fall League, where he’ll make up for time lost to an early-season right ankle sprain.
Twins: Brandon Winokur, OF/SS/3B (No. 14)
Winokur provides an exciting power-speed combination in a 6-foot-6 package and he set career highs in homers (17) and steals (26) at age 20 in the High-A Midwest League. He needs to keep refining his approach (26.6 percent K rate in his Minor League career) to get to those tools more consistently. Winokur split time between short, third and center field in 2025, but he’ll focus on the dirt -- primarily at short -- this fall.
White Sox: Braden Montgomery, OF (CWS No. 1/MLB No. 35)
The White Sox considered taking Montgomery with the No. 5 overall pick in the 2024 Draft before he broke his right ankle on a bad slide at Texas A&M, then acquired him as part of the Garrett Crochet trade with the Red Sox last December. He comes with well above-average raw power and arm strength and batted .270/.360/.444 with 12 homers and 14 steals in 121 games while advancing from Single-A to Double-A in his pro debut.
AMERICAN LEAGUE WEST
Angels: Juan Flores, C (No. 18)
Flores joined the Angels as part of their 2023 international signing class and spent the 2025 season at age 19 in High-A ball. He was inconsistent at the plate, finishing with a .624 OPS, and while he still needs refinement behind the dish, the fourth-youngest player headed to the Fall League has strong catch-and-throw skills. Getting to catch more advanced arms in the AFL will certainly aid in his defensive development.
Astros: Walker Janek, C (No. 4)
Some evaluators rate Janek as the best prospect in Houston's system because of his combination of raw power, receiving skills and arm strength. A 2024 first-rounder from Sam Houston, he hit .263/.333/.433 with 12 homers and 30 steals in 92 games in High-A.
Athletics: Tommy White, 3B (No. 7)
While minor injuries limited White to 93 games played in his first full season of pro ball, the 2024 second-rounder did make it to Double-A, where he’s helped Midland reach the Texas League championship series and hit .311 following his promotion from High-A Lansing. He hit a combined 12 homers during the regular season, and there’s much more raw power for him to tap into.
Mariners: Jonny Farmelo, OF (SEA No. 7/MLB No. 75)
We’re excited to potentially see a fully healthy Farmelo this fall. The 2023 draftee was off to a strong start in 2024 when a torn ACL in June ended his season and slowed him early this year. So did a rib stress reaction, leading to just 29 games played in 2025. At his best, he has five potential tools with at least plus speed.
Rangers: Sebastian Walcott, SS/3B (TEX No. 1/MLB No. 6)
Hailed as potentially the most talented Bahamian player ever even before he signed for $3.2 million in 2023, Walcott has lived up to those expectations while showing off some of the best raw power and arm strength in the Minors. Just 19, he spent all year in Double-A and slashed .255/.355/.386 with 13 homers and 32 steals in 124 games.
NATIONAL LEAGUE EAST
Braves: Drue Hackenberg, RHP (No. 10)
Hackenberg, who has had brothers previously taken in the MLB, NFL and MLS Drafts, had a very solid first full season of pro ball in 2024, pitching across three levels and finishing with a 3.07 ERA, 10 K/9 and a GO/AO of 1.64. He kept getting ground ball outs in 2025 (1.51 GO/AO), but he didn’t miss as many bats while his walk and hit rates went up. He also missed time, so he’s trying to make up for lost innings while also getting back on track.
Marlins: Starlyn Caba, SS/2B (No. 5)
One of the best defenders in the Minors, Caba joined the Marlins as part of the Jesús Luzardo trade with the Phillies last December. A sprained left thumb limited him to 51 games and a .222/.335/.278 line in Single-A, but he still exhibited smooth actions, quality range to both sides, solid arm strength and plus speed.
Mets: Chris Suero, C/OF/1B (No. 15)
A Bronx native, Suero signed with the Mets for $10,000 out of the Dominican Republic in March 2022, and now, he’s one of the most interesting prospects in a loaded New York system. He shows plus speed in his 5-foot-11 frame, leading to a career-high 35 steals between High-A and Double-A this season, but the bulk of his work remains at catcher – a rarity for someone with those wheels. He also set a new best with 16 homers but will have to prove he can make enough contact to get to at least average pop. He also saw time in left field and first base this season, giving Scottsdale some roster flexibility.
Nationals: Seaver King, SS (No. 7)
A former standout at Division II Wingate and Wake Forest, the 2024 10th overall pick didn’t exactly hit the ground running with a .244/.294/.337 line and six homers in 125 games at High-A Wilmington and Double-A Harrisburg in his first full season.
Phillies: Dante Nori, OF (No. 6)
Nori, the Phillies’ first-rounder in 2024, hit well enough across two levels of A ball to make Reading’s roster to finish off the year. The 20-year-old drafted out of the Michigan high school ranks posted a .261/.361/.372 slash line across all three levels last season, showing off impressive bat-to-ball skills, the ability to run (52 steals) and excellent defense in center field. This is Rincon's second year in a row representing the Phillies in the AFL. He can really play short, but has had trouble finding consistency on the offensive end and in staying healthy, with only 230 games on his resume since being drafted in 2022.
NATIONAL LEAGUE CENTRAL
Brewers: Luke Adams, 1B/3B (No. 8)
Adams is an on-base king with a career .423 mark over four Minor League seasons, in part because he can be overly passive at the plate at times and also in part because he gets plunked so much. (His 85 HBPs over the last three seasons are second-most in the Minors.) Adams, who dealt with a left shoulder contusion for part of the summer, hit .232/.409/.450 with 11 homers, 10 steals and a 160 wRC+ in 64 games with Double-A Biloxi this season.
Cardinals: Chen-Wei Lin, RHP (No. 16)
At 6-foot-7, the 23-year-old right-hander will be one of the tallest pitchers in the AFL this year, and he has some big stuff beyond the size. His fastball sits 95-97 (touching the occasional triple-digits), while his 87-90 mph changeup and 82-84 mph slider can generate tons of whiffs, particularly the cambio with its similar horizontal movement to the heater. Lin struck out 20 batters over 9 ⅔ innings in a four-start sample with Double-A Springfield, but his lack of control can be maddening as he walked nine in the same sample.
Cubs: Cole Mathis, 1B/3B (No. 17)
The Cubs plucked Mathis in 2024's second round out of the College of Charleston because they liked his patient approach and 20-homer upside. He had Tommy John surgery shortly after signing and played just 29 games as a DH in his pro debut this year, batting .215/.336/.402 in Single-A.
Pirates: Esmeryln Valdez, 1B/OF (No. 15)
Let this be our humble request for Valdez to participate in this year’s AFL Home Run Derby. At age 21, Valdez slugged his way from High-A to Double-A and finished with 26 homers and a .520 SLG. This wasn’t a hitter-friendly Greensboro creation: Valdez’s numbers were actually better on the road in 2025 and his 156 wRC+ trailed only Konnor Griffin among Pirates prospects who amassed more than 400 plate appearances.
Reds: Alfredo Duno, C (CIN No. 2/MLB No. 48)
The fifth-youngest player on a Fall League roster, the 19-year-old Duno is coming off of a big year with Single-A Daytona, finishing with a .948 OPS and helping the Tortugas reach the Florida State League championship series. The right-handed-hitting backstop’s 164 wRC+ topped all Reds Minor League hitters and he had a 1.263 OPS from Aug. 1 through the end of the FSL season.
NATIONAL LEAGUE WEST
D-backs: Jansel Luis, INF (No. 12)
A switch-hitter, Luis can get swing-happy at times and chase pitches, but he can certainly put bat on ball on pitches in the zone, leading to a .304 average and 16.3 percent K rate in 102 games with High-A Hillsboro this season. Three of his five homers in 2025 came as a righty, despite getting 257 fewer plate appearances from that side. The 20-year-old got the lion’s share of his starts at second but also saw time at short and third.
Dodgers: Josue De Paula, OF (LAD No. 1/MLB No. 13)
Signed out of the Dominican Republic for $397,500 in 2022, De Paula has an impressive combination of swing decisions and exit velocities for a 20-year-old. Compared as a slightly smaller but more athletic version of Yordan Alvarez, he hit .263/.406/.421 with 12 homers and 32 steals in 98 High-A games before going 0-for-18 in Double-A.
Giants: Maui Ahuna, SS (No. 12)
Like three-time All-Star and four-time Gold Glover Brandon Crawford, Ahuna was a slick-fielding college shortstop who dropped to the fourth round after slumping as a junior. Drafted in 2023 out of Tennessee, Ahuna had Tommy John surgery in his first full pro season but rebounded to slash .277/.382/.436 with 10 steals in 48 games between two Class A stops in his second.
Padres: Lamar King Jr., C/1B (SD No. 14)
Fellow backstop Ethan Salas, who missed much of the season with a back injury, was on the initial Arizona Fall League roster, only to be replaced at the same position by King. But the 2022 fourth-rounder is more than just a last-second straight swap. After dealing with his own injuries (mostly with his shoulder) through his first two full seasons, King broke out with a .286/.370/.408 line and 118 wRC+ in 81 games at Single-A Lake Elsinore. More importantly, he folded in even more work behind the plate after previously being relegated to first-base/DH duties. After a quieter performance at High-A Fort Wayne, the right-handed slugger has a chance to adjust and potentially take off in the hitter-friendly AFL.
Rockies: Charlie Condon, 1B/OF (COL No. 2/MLB No. 61)
First it was a hand injury he tried to play through during his summer debut. Then it was a broken wrist suffered in Spring Training. Suffice it to say we haven’t seen the real Condon, the No. 3 overall pick in the 2024 Draft, at his best yet. There were glimpses this year, with a .317/.425/.416 line in June earning him a bump to Double-A, then a .998 OPS with six homers at the higher level in August. Here’s hoping we see more of that in Arizona.
