Here's a look at Tuesday's top Minor League performers from each team's Top 30 Prospects list:
AMERICAN LEAGUE EAST
Blue Jays: Yennsy Diaz, RHP (No. 23) -- 7 IP, 2 H, 0 R, 2 BB, 1 HBP, 8 K (Double-A New Hampshire)
Diaz, 22, has posted 15 straight scoreless frames for New Hampshire after dominating in his second straight seven-inning outing. He set a season high by striking out eight -- one fewer than the combined total from his past three starts -- and threw 64 of 98 pitches for strikes, including 15 swinging strikes. It was the fourth scoreless performance in eight outings (seven starts) for the Dominican right-hander, who's pitched to a 3.14 ERA over 43 innings in his first Double-A campaign. The Blue Jays added Diaz, who pairs a mid-90s fastball with hard breaking ball, to their 40-man roster after the 2018 season.

Orioles: Grayson Rodriguez, RHP (No. 4, MLB No. 97) -- 5 IP, 4 H, 1 R, 2 BB, 6 K (Class A Delmarva)
GrayRod allowed one earned run or less for the sixth time in seven starts for Delmarva, furthering his success in what already has been a dominant full-season debut by the 2018 first-rounder (No. 11 overall pick). To go along with his South Atlantic League-leading 1.50 ERA, the 19-year-old righty has held hitters to a .175 average while striking out 53 in 36 innings (13.3 K/9). Including his pro debut, Rodriguez has registered a 1.46 ERA and 73/18 K/BB in 55 1/3 innings across two levels.
Orioles prospects stats »
Rays: Matthew Liberatore, LHP (No. 5, MLB No. 51) -- 5 IP, 1 H, 2 R (1 ER), 5 BB, 8 K (Class A Bowling Green)
The 19-year-old southpaw matched his career high in strikeouts but set another by issuing five walks against West Michigan in his second full-season start. He gave up an RBI triple in the second inning and was charged with an unearned run in the fifth before departing the game after 86 pitches (50 strikes). Liberatore, the No. 16 pick in last year’s Draft, has given up one run on five hits in 10 innings so far this season after pitching to a 1.38 ERA with 37 strikeouts in 32 2/3 innings last summer across a pair of Rookie levels in his pro debut.
Rays prospects stats »
Red Sox: Bobby Dalbec, 3B (No. 3) -- 2-for-4, solo HR (8), 2 R (Double-A Portland)
The 23-year-old slugger connected on his sixth home run in 20 games this month and was one of five Sea Dogs players to tally multiple hits in their win over Trenton. He’s batting .304 with a 1.089 OPS in May, during which he’s improved his season average from .197 to .252. Dalbec has gone deep eight times so far this season after setting a career high with 32 bombs across two levels in 2018.
Red Sox prospects stats »
Yankees: Josh Stowers, OF (No. 25) -- 1-for-4, solo HR (2) (Class A Charleston)
Stowers, whom the Yankees acquired via a January trade with the Mariners, hit .313 in April, but has slowed down a bit and is hitting .219 over the month of May. Stowers is 3-for-26 over his past six games and is hitting .267 this season. The homer was just the second of the season for Stowers, but power isn't really his game and he's at his best when he's hitting line drives.
Yankees prospects stats »
AMERICAN LEAGUE CENTRAL
Indians: Nick Sandlin, RHP (No. 17) -- 1 1/3 IP, 0 H, 0 R, 1 BB, 2 K (Double-A Akron)
Sandlin has been dominant in relief this season and hasn't surrendered a run in six straight appearances, a span of 8 1/3 innings. The 22-year-old, a second-round pick from last year's Draft, has a 0.71 ERA through 11 appearances and has struck out 19, compared to six walks, over 12 2/3 innings. Sandlin pitched across four levels last year and struck out 36 in 24 innings.
Indians prospects stats »
Royals: Brady Singer, RHP (No. 1, MLB No. 50) -- 7 IP, 5 H, 0 R, 1 BB, 6 K (Class A Adv Wilmington)
The 2018 first-rounder (No. 18 overall pick) completed the longest outing of his career as he lowered his ERA to 2.13 through nine starts in his first pro season. He's improving with every start, as Tuesday's performance gives him 13 straight scoreless innings after Singer struck out a career-high 10 over six scoreless frames in his last turn. For the season, the 22-year-old righty has compiled 49 strikeouts and 11 walks while allowing just one home run in 50 2/3 innings.
Royals prospects stats »
Tigers: Matt Manning, RHP (No. 2, MLB No. 48) -- 6 2/3 IP, 2 H, 0 R, 2 BB, 10 K (Double-A Erie)
Manning walked the second batter of the game but retired the the next 16 hitters as he carried a no-hit bid into the sixth inning. The 21-year-old induced 20 whiffs and found the zone with 65 of 96 pitches en route to his second double-digit strikeout performance of the season. It gives the 6-foot-6 righty an Eastern League-leading 68 strikeouts (against 13 walks) in 54 innings (nine starts) on the year, while his ERA sits at 2.17 after his latest gem.
Tigers prospects stats »
Twins: Ryan Jeffers, C (No. 16) -- 2-for-3 (Class A Adv Fort Myers)
Jeffers, a second-round pick from last year's Draft, is hitting .292 after his latest multihit effort. The 21-year-old showed impressive power at UNC Wilmington and has homered 10 times over 97 games to begin his professional career.
Twins prospects stats »
White Sox: Steele Walker, OF (No. 11) -- 1-for-4, solo HR (2), BB (Class A Adv Winston-Salem)
Walker’s two-out homer in the third inning was his second deep fly so far this season and accounted for half of the Dash’s scoring against Fayetteville. Selected by the White Sox in the second round of the 2018 Draft, the 22-year-old outfielder batted .365/.437/.581 over 20 games with Class A Kannapolis but has produced a .177/.316/.306 line in 18 games since his promotion to the Carolina League.
White Sox prospects stats »
AMERICAN LEAGUE WEST
A’s: Jonah Heim, C (No. 29) -- 2-for-3, 2 RBI, 2 BB (Double-A Midland)
Heim reached base four times as he snapped out of a mini 1-for-12 skid. Heim, 23, came through with run-scoring singles in the eighth and ninth innings, but it didn't prove to be enough as Midland's comeback attempt fell short. The catcher, acquired via a trade with the Rays in December 2017, is putting together a strong season in Double-A, hitting .282/.366/.368 through 32 games.
A's prospects stats »
Angels: Matt Thaiss, 1B/3B (No. 8) -- 3-for-5, solo HR (4), 2 R (Triple-A Salt Lake)
Thaiss' fourth homer of the year came in the fifth inning, but it wasn't enough to help Salt Lake come away with a win. The 24-year-old is hitting .280 through 42 games and is coming off a 2018 campaign during which he set a career high with 16 homers and hit .280/.335/.467 in 125 games over two levels.
Angels prospects stats »
Astros: Jose Hernandez-Urquidy, RHP (No. 30) -- 6 IP, 3 H, 1 R, 1 BB, 12 K (Triple-A Round Rock)
Hernandez-Urquidy showed impressive swing-and-miss stuff as he cruised through the San Antonio lineup. The 24-year-old, whom the Astros purchased from the Mexican League's Mexico City Red Devils in 2015, began the year with Double-A Corpus Christi, but was bumped up after seven appearances. While it's only been a pair of outings, Hernandez-Urquidy has adjusted well to the new level and is 2-0 with 20 strikeouts over 11 innings. While those numbers, particularly his 12 strikeouts in this most recent outing, are impressive, they aren't unheard of for Hernandez-Urquidy, who posted two 12-strikeout games and one 13-strikeout game in 2016.
Astros prospects stats »
Mariners: Jarred Kelenic, OF (No. 2, MLB No. 42) -- 1-for-3, solo HR (7), 2 R, BB (Class A West Virginia)
While Kelenic has cooled off after hitting .337 in April, the 19-year-old is still putting together an impressive full-season debut, hitting .299/.385/.518 through 42 games. Kelenic hit .286 after the Mets grabbed him in the first round of last year's Draft, but the outfielder was traded to Seattle as part of the Edwin Diaz/Robinson Cano trade in December. Prior to the Draft, Kelenic was viewed as one of the best hitters in the class and he's certainly been living up to the billing thus far.
Mariners prospects stats »
Rangers: Sam Huff, C/1B (No. 21) -- 2-for-4, HR (17), 2B, 2 R (Class A Adv Down East)
Not even a promotion to Down East could slow down Huff, who has been one of the hottest hitters in the Minors this season. The 21-year-old got off to a rapid start and hit .333 with 15 homers through 30 games for Hickory before he was promoted to the Wood Ducks, with whom he has gone on to hit .289 with a pair of homers in 12 games. This year has been a offensive breakthrough for Huff, who hit .249 and .241 in 2017 and '18, respectively.
Rangers prospects stats »
NATIONAL LEAGUE EAST
Braves: Bryse Wilson, RHP (No. 7, MLB No. 80) -- 7 IP, 3 H, 2 R, 0 BB, 6 K (Triple-A Gwinnett)
Wilson carried a no-hit bid into the fifth inning and didn't give up the two runs until the seventh inning, when Charlotte's Matt Skole tagged him for a two-run homer. The 21-year-old righty has completed at least seven frames in back-to-back starts for the Stripers after a shaky start to his season. He's already appeared in two games (one start) for the Braves this season and should be back in the Major Leagues when a need arises.
Braves prospects stats »
Marlins: Trevor Rogers, LHP (No. 15) -- 7 IP, 5 H, 2 R (0 ER), 2 BB, 10 K (Class A Adv Jupiter)
Rogers set his season-high mark in strikeouts but ultimately took the loss for the Hammerheads as the result of a pair of unearned runs allowed in the first inning. The 2017 first-round pick from the New Mexico prep ranks has completed seven innings of zero-earned-run ball in three of eight starts this season, though none have netted him a win. He’s been piling up strikeouts lately, as Tuesday’s outing gives him 27 punchouts over his last 17 2/3 frames. After finishing his first full season with a 5.82 ERA in 72 2/3 innings with Class A Greensboro, the 21-year-old lefty has pitched to 2.18 ERA through 45 1/3 innings (eights starts) in the Florida State League in 2019.
Marlins prospects stats »
Mets: David Peterson, LHP (No. 5) -- 5 IP, 3 H, 2 R (0 ER), 2 BB, 8 K (Double-A Binghamton)
The Mets' 2017 first-rounder turned in his fourth straight start in which he allowed one earned run or fewer while completing at least five innings. Peterson won this one, unlike the previous three, and did so while throwing 56 of his 88 pitches for strikes. In his first Double-A campaign, the 23-year-old left-hander has pitched to a 3.93 ERA with 43 strikeouts in 36 2/3 innings (eight starts).
Mets prospects stats »
Phillies: Simon Muzziotti, OF (No. 12) -- 1-for-4, solo HR (2) (Class A Adv Clearwater)
The 20-year-old Venezuelan is hitting .303 on the season and .341 over his last 10 games, during which he has five multihit performances. Muzziotti also has hit both of his home runs in that stretch, giving him a new career-high total after he homered once in 163 games across his first three pro campaigns.
Phillies prospects stats »
Nationals: Raudy Read, C (No. 19) -- 2-for-4, HR (6), 3 RBI (Triple-A Fresno)
Read, who reached the Majors in 2017 only to miss most of last season serving an 80-game PED-related suspension, swatted his fourth homer in eight games for the Grizzles. He's gone deep six times in 24 games this season after hitting just three homers in 53 games last year between Double-A and Triple-A.
Nationals prospects stats »
NATIONAL LEAGUE CENTRAL
Brewers: Tristen Lutz, OF (No. 4) -- 2-for-5, HR (4), 3 RBI (Class A Adv Carolina)
Lutz is starting to heat up at the plate, as Tuesday's two-hit effort gives him a .297 average in 16 games this month after he struggled through April to a .182/.250/.299 finish in 21 games. The No. 34 overall pick in the 2017 Draft was a slow starter in his first full season, too, putting up a .677 OPS in the first half and then slashing .263/.346/.456 (.802 OPS) over his final 61 games.
Brewers prospects stats »
Cubs: Miguel Amaya, C (No. 2, MLB No. 81) -- 2-for-4, 2B, R (Class A Adv Myrtle Beach)
Amaya's average may sit at an underwhelming .218 after his second straight multihit effort, but he's OPS-ing .762 as a 20-year-old in the Florida State League, with five homers, 20 RBIs and 22/29 BB/K in 36 games. What's more, the Panamanian backstop has been very good defensively, throwing out 40.8 percent (20 of 49) attempted basestealers.
Cubs prospects stats »
Cardinals: Dylan Carlson, OF (No. 6) -- 1-for-4, HR (8), 2 RBI (Double-A Springfield)
The 20-year-old switch-hitter hit a two-run shot against Dodgers No. 3 prospect Dustin May for his fourth home run in the past six games. In the process Carlson extended his hitting streak to 10 games, during which he's batting .341 with nine extra-base hits and 12 RBIs. The 2016 first-rounder is having a breakout season in his first Double-A campaign, hitting .289/.358/.548 with 22 extra-base hits, 31 RBIs and 32 runs in 42 games for the Cardinals.
Cardinals prospects stats »
Pirates: Mitch Keller, RHP (No. 1, MLB No. 21) -- 7 IP, 6 H, 1 R, 1 BB, 6 K (Triple-A Indianapolis )
Keller improved to 5-0 and lowered his ERA to 3.45 via his longest start of the season. It also marked the first time since April 21 that the 23-year-old has held opponents to one run or fewer, as he entered the day having pitched to a 4.95 ERA over his last four starts. Keller is allowing too many baserunners this season (1.43 WHIP, 20 BB), but he's still missing a healthy number of bats (56 K) and consistently pitching deep into games.
Pirates prospects stats »
Reds: James Marinan, RHP (No. 20) -- 7 IP, 4 H, 3 R (1 ER), 3 BB, 2 K (Class A Dayton)
Marinan, 20, had allowed 18 earned runs over his last 20 2/3 innings before getting back on track Tuesday with seven innings of three-run (one earned) ball against Lake County. It matched his longest outing this season, both of which have taken place within his last four turns in the rotation. Marinan pitched to a 0.84 ERA over 10 2/3 innings in the Rookie-level Arizona League last summer after the Dodgers acquired him from the Reds in a July trade.

NATIONAL LEAGUE WEST
D-backs: Domingo Leyba, 2B/SS (No. 24) -- 4-for-5, 3 2B, 5 RBI, 2 R (Triple-A Reno)
The 23-year-old switch-hitter recorded his second four-hit game this season and is now hitting an even .500 (9-for-18) with two home runs, five doubles, nine RBIs and eight runs scored over his last four games. His overall batting line has improved in that span from .285/.342/.431 to .309/.362/.506 as a result of the hot streak, and he's now accrued 20 extra-base hits and 26 RBIs through 41 games in his first Triple-A campaign.
D-backs prospects stats »
Dodgers: Will Smith, C (No. 5) -- 3-for-4, 2 HR (8), 3 RBI, BB (Triple-A Oklahoma City)
Smith’s bat proved the difference as he powered Oklahoma City to a 6-4 win over New Orleans with his second career multi-homer game. After going deep in the third (solo) and fifth (two-run) innings and reaching base in his first four trips to the plate, Smith grounded out to shortstop on the seven pitch of his at-bat in the ninth inning, ending his bid for his second four-hit effort in a six-game span. The 24-year-old backstop and former first-round pick (2016) has hit five of his eight homers this season in the last 10 games. With a .281 average 17 extra-base hits and 26 RBIs in 35 games, Smith is faring much better this year in his return to the Triple-A after he struggled at the level (.138/.206/.218 in 25 games) late last season.
Dodgers prospects stats »
Giants: Aramis Garcia, C (No. 21) -- 2-for-4, solo HR (5), 2 R (Triple-A Sacramento)
Garcia, a second-round pick from the 2014 Draft, went 1-for-6 over three games in the Majors, but has hit well since being back with Sacramento. Garcia is 5-for-14 with a homer over the past four games, bringing his average up to .217 for the River Cats. Garcia hit .286 over 19 games with the Giants last year and .233 over 90 games across two levels in the Minors.
Giants prospects stats »
Padres: Luis Urias, 2B (No. 3, MLB No. 24) -- 3-for-5, HR (12), 3 RBI, R (Triple-A El Paso); Esteury Ruiz, 2B (No. 25) -- 3-for-3, HR (5), 2B, 2 R, SB (Class A Adv Lake Elsinore)
Urias notched multiple hits for the second straight game and continued to show off his power, homering for the fifth time in the past 10 games. Urias, who has already eclipsed his 2018 homer total of 10, is now batting .350/.439/.775 in 29 games in the Minors. Ruiz impacted the game with his power and speed from the bottom of the lineup, as he connected on his fifth home run of the year and swiped his 15th bag as part of a perfect night at the plate. The 20-year-old is hitting .259/.299/.413 through 39 games this season after slashing .253/.324/.403 with 12 homers and 49 steals a year ago in his first full season.
Padres prospects stats »
Rockies: Riley Pint, RHP (No. 7) -- 1 IP, 0 H, 0 R, 0 BB, 2 K (Class A Asheville)
The former No. 4 overall Draft pick (2016) is yet to advance past the Class A level due to his massive control problems, though things have been going much better for him of late after a rocky start to his season. Since he allowed four earned runs on four walks and two hits on May 2, Pint has strung together seven straight scoreless appearances for the Tourists during which he’s allowed two hits and, more importantly, zero walks while striking out eight in seven innings. The hard-throwing 21-year-old still sports a 10.13 ERA for the season, though it’s significantly better than the 23.14 mark he had after the May 2 outing.
