Here's a look at Sunday's top Minor League performers from each team's Top 30 Prospects list:
AMERICAN LEAGUE EAST
Blue Jays: Cavan Biggio, 2B/OF (No. 9) -- 1-for-3, RBI (Triple-A Buffalo)
Biggio has gotten off to a fast start in his Triple-A debut, hitting .327 with six homers through 33 games. The 24-year-old drastically improved his stock last year as he hit a career-high 26 homers and was named Eastern League MVP.

Orioles: DJ Stewart, OF (No. 15) -- 1-for-2, HR, 2 RBI (Triple-A Norfolk)
Stewart came through with his sixth homer of the year in the sixth inning of Norfolk's loss to Buffalo. Stewart, 25, hit 15 homers last season, including three in the Majors, after hitting 21 in 2017. Stewart is hitting .259 this season, but is starting to heat up as he's hitting .458 through eight games this month.
Orioles prospects stats »
Rays: Colin Poche, RHP (No. 17) -- 2 IP, 4 H, 0 R, 1 BB, 2 K (Triple-A Durham)
The four hits matched a season high, but Poche still managed to put a pair of zeros up on the board for the fourth time in as many appearances. The 25-year-old has a 6.58 ERA this season, but that's largely inflated due to a couple of rough outings. Poche is currently in the middle of an eight-inning scoreless streak. Poche was traded to the Rays from the D-backs last May so the 2019 season will be his first full year in the organization.
Rays prospects stats »
Red Sox: Bobby Poyner, LHP (No. 23) -- 1 IP, 1 H, 0 R, 0 BB, 3 K (Triple-A Pawtucket)
Poyner threw 13 of his 17 pitches for strikes as he struck out the side in a scoreless inning of relief. Poyner, a former 14th-round pick (2015), made his MLB debut in 2018 and appeared in a pair of games for the Red Sox earlier this year. In Triple-A, Poyner has allowed eight earned runs in 13 innings.
Red Sox prospects stats »
AMERICAN LEAGUE CENTRAL
Royals: Austin Cox, LHP (No. 22) -- 7 IP, 3 H, 0 R, 0 BB, 8 K (Class A Lexington)
Cox set a career high for innings and a season high for strikeouts as he fired 65 of his 89 pitches for strikes against Augusta. Cox, the Royals fifth-round pick from last year's Draft, had given up 12 runs over his past three starts (15 innings) entering Sunday, but bounced back with his best performance since spinning six scoreless frames on April 19.
Royals prospects stats »
Tigers: Jake Rogers, C (No. 13) -- 2-for-4, 2 2B, 3 RBI (Double-A Erie)
Rogers boosted his average up over .300 (.309) for the first time this season as part of a multihit effort for Erie. Rogers spent the 2018 season with Erie and hit .219 over 99 games. The 24-year-old is regarded as the best defensive catcher in the Minors and it will be his defense that gets him to the Majors, but the increased offensive production is certainly welcomed.
Tigers prospects stats »
Twins: Luke Raley, OF/1B (No. 26) -- 2-for-4, RBI (Triple-A Rochester)
Raley, who the Twins acquired from the Dodgers at last year's Trade Deadline, has fared well in his first taste of Triple-A, slashing .299/.364/.542 through 28 games. Raley has hits in 10 of his past 11 games, including seven multihit efforts. The 24-year-old hit .275 over 120 games last season, all at the Double-A level, but split between two organizations.
Twins prospects stats »
White Sox: Jose Ruiz, RHP (No. 23) -- 1 IP, 1 H, 0 R, 0 BB, 2 K (Triple-A Charlotte)
After posting a 5.40 ERA through 11 games (10 innings) with Chicago, Ruiz was optioned to Charlotte where he's been lights out in two appearances. The 24-year-old, who the White Sox claimed off waivers in December 2017, has thrown a pair of scoreless innings, yielding two hits and striking out three.
White Sox prospects stats »
AMERICAN LEAGUE WEST
A’s: Skye Bolt, OF (No. 19) -- 1-for-3, 3B, BB (Triple-A Las Vegas)
Bolt went 1-for-4 over three games in the Majors and was optioned back to Las Vegas on May 7. Bolt went 0-for-5 with five strikeouts in his first game back, but rebounded to go 3-for-7 over the weekend. The speedy outfielder hit his second triple of the season and is hitting .315 through 25 games with the Aviators.
A's prospects stats »
Angels: Jared Walsh, OF/1B/LHP (No. 20) -- 1-for-3, 2B (Triple-A Salt Lake)
Walsh has doubled in back-to-back games and is ever so close (.299) to reaching the .300 mark for the first time this season. While the 25-year-old has fared well in the early going offensively, he's also performed well on the mound. Entering the season the lefty had appeared in 10 games since he was selected in the 39th round of the 2015 Draft. However, the Angels have begun to use him more as a two-way prospect and he's pitched to a 3.60 ERA over five appearances this season.
Angels prospects stats »
Astros: Yordan Alvarez, OF (No. 3, MLB No. 38) -- 2-for-4, HR, 3 RBI (Triple-A Round Rock)
Alvarez put the Express out in front with a three-run homer in the first inning, continuing what has been an impressive start to the season. The 21-year-old is hitting .402 with 15 homers and 47 RBIs through 33 games. What's more, after hitting .387 in April, Alvarez has somehow picked up the pace and is raking at a .489 clip through 12 games in May.
Astros prospects stats »
Mariners: Cal Raleigh, C (No. 13) -- 2-for-4, HR, 5 RBI (Class A Advanced Modesto)
Raleigh, a 2018 Draft pick (third round), set a career high with five RBIs and hit his second homer of the year to help Modesto top Lancaster. The 22-year-old, taken out of Florida State, is hitting .217 through the first 30 games of his full-season debut.
Mariners prospects stats »
Rangers: Sam Huff, C (No. 21) -- 2-for-3, 2B (Class A Advanced Down East)
Huff hit .333 with 15 homers in 30 games with Class A Hickory before he was promoted to Down East. However, the new level doesn't appear to have had much of an impact on Huff's bat. The 21-year-old has hits in three of the four games he's played with the Wood Ducks, including a pair of multihit efforts. Huff hit .241 a season ago and was a seventh-round pick from the 2016 Draft.
Rangers prospects stats »
NATIONAL LEAGUE EAST
Braves: Alex Jackson, C (No. 27) -- 1-for-4, HR, RBI (Triple-A Gwinnett)
Jackson got off to a slow start this season -- both with Gwinnett and in Atlanta where he went 0-for-10 -- and eventually wound up on the injured list for a short stint. However, since he's been back on the field, Jackson is hitting .355 and has hits in seven of eight games. The former first-round pick (2014) is driving the ball well, too. Jackson has homered five times over the past eight games, including four homers over his past five games.
Braves prospects stats »
Marlins: Isan Diaz, SS (No. 6) -- 2-for-4, HR, 3 RBI (Triple-A New Orleans)
Diaz entered the day mired in an 0-for-15 slump, but promptly broke out of it with an RBI single in the first inning and then followed that up with a two-run homer in the second. The 22-year-old is hitting .226 through 24 games this season after hitting .232 over 199 games, including 36 games (.204) with New Orleans, last year.
Marlins prospects stats »
Mets: Ronny Mauricio, SS (No. 2, MLB No. 95) -- 1-for-3, BB (Class A Columbia)
The 18-year-old shortstop has a hit in three straight games and in seven of his past eight after singling in Columbia's loss to Rome. Mauricio, who signed with the Mets in 2017, is hitting .266 through 31 games in his full-season debut.
Mets prospects stats »
Nationals: Kyle McGowin, RHP (No. 30) -- 5.2 IP, 1 H, 0 R, 1 BB, 11 K (Triple-A Fresno)
McGowin matched his career high (set in 2018) for strikeouts in one of his best starts of the season for Fresno. The 27-year-old has kept opponents off the board in two of his past three starts and has pitched to a 4.32 ERA through eight starts with Fresno. McGowin has also spent some time with the Nationals this season, but he struggled to get outs and gave up five runs in 7 2/3 innings.
Nationals prospects stats »
NATIONAL LEAGUE CENTRAL
Brewers: Corey Ray, OF (No. 2, MLB No. 92) -- 3-for-5, 2B, HR, 2 RBI (Triple-A San Antonio), Mauricio Dubon, SS/2B (No. 5) -- 2-for-5, 2 HR, 3 RBI (Triple-A San Antonio)
Ray has officially found his rhythm. The 24-year-old went 1-for-10 in his first three games back from the injured list. Since then, he's gone 6-for-14 with homers in three straight games. Ray, who hit a career-best 27 homers last season, is still hitting just .211 this season, but his recent surge is certainly encouraging. Dubon, hitting .273 this season, also came up big for the Missions. Dubon, who has multiple hits in three straight games, hit two homers for the first time in his career and has already homered five times this season. His career high is eight homers, set in 2017.
Brewers prospects stats »
Cubs: Aramis Ademan, SS (No. 6) -- 2-for-4, 3B, RBI (Class A Advanced Myrtle Beach)
Ademan, who signed with the Cubs in 2015 out of the Dominican Republic, returned to Myrtle Beach after he hit .207 over 114 games with the Pelicans in 2018. The 20-year-old is off to a better start this time around and is hitting .256 through 28 games.
Cubs prospects stats »
Cardinals: Ryan Helsley, RHP (No. 9) -- 2.2 IP, 1 H, 0 R, 1 BB, 3 K (Triple-A Memphis)
Since giving up four runs on May 5, Helsley has turned in a pair of scoreless outings. The 24-year-old, a fifth-round pick from the 2015 Draft, threw 22 of his 38 pitches for strikes on Sunday and lowered his ERA to 3.94. Helsley made his Major League debut earlier this year and appeared in a trio of games with the Cardinals.
Cardinals prospects stats »
Pirates: Jared Oliva, OF (No. 12) -- 1-for-3, BB (Double-A Altoona)
Oliva, the Pirates seventh-round pick from the 2017 Draft, hit .275 over 108 games in his professional debut last season. The Pirates bumped Oliva up to Double-A this year where he's gotten off to a slow start. Oliva did miss some time with a concussion, but when he's been healthy, he's hitting .222 though 24 games.
Pirates prospects stats »
Reds: Jimmy Herget, RHP (No. 18) -- 1 IP, 1 H, 0 R, 1 K (Triple-A Louisville)
Herget has held opponents scoreless in five of his past six outings. The 25-year-old threw 15 of his 17 pitches for strikes on Sunday, but command has been an issue throughout the season as Herget has issued 16 walks in 17 2/3 innings. Herget posted a 3.47 ERA at Triple-A last year (50 games) and is back with the Bats again in 2019.
Reds prospects stats »
NATIONAL LEAGUE WEST
Dodgers: Omar Estevez, SS/2B (No. 19) -- 2-for-4, 2 BB (Double-A Tulsa)
After a pair of hitless games, Estevez got back in the hit column with a pair of singles for the Drillers. The 21-year-old is off to a strong start, hitting .330, in his first Double-A experience. After signing with the Dodgers out of Cuba in 2015, Estevez spent the 2016 season at the Class A level before spending each of the past two years at Class A Advanced, where he hit .256 and .278.
Dodgers prospects stats »
Giants: Williams Jerez, LHP (No. 29) -- 1.1 IP, 1 H, 0 R, 0 BB, 2 K (Triple-A Sacramento)
That's six straight scoreless appearances (eight innings) for Jerez following Sunday's 17-pitch win over El Paso. The hard-throwing lefty spun a scoreless frame in his lone appearance with the Giants this season and has pitched to a 1.96 ERA through 14 appearances with the River Cats. The Red Sox drafted Jerez in 2011 (second round) as an outfielder, but converted him to the mound in 2014. Jerez was traded to the Angels last July and then to the Giants in March.
Giants prospects stats »
Padres: Esteury Ruiz, 2B (No. 26) -- 2-for-3, HR, 3 RBI (Class A Advanced Lake Elsinore)
The 20-year-old hit his second homer over the past three games and his fourth of the season for the Storm. Ruiz got off to a slow start this season, but is hitting .324 over 11 games in May and is already a third of the way to his career high in homers, which he set last season. Ruiz signed with the Royals in 2015 and then was traded to the Padres at the 2017 Trade Deadline.
Padres prospects stats »
Rockies: Ryan Feltner, RHP (No. 23) -- 6 IP, 5 H, 1 R, 1 BB, 6 K (Class A Asheville)
Feltner has completed six innings in three of his past four starts and has struck out six or more in all four of those outings as well. The 22-year-old has a 4.46 ERA this season and Sunday's start was actually the first in which he allowed fewer than two runs. Feltner posted a 0.88 ERA over nine starts last year, after he was selected in the fourth round of the Draft.
