Here's a look at Saturday's top Minor League performers from each team's Top 30 Prospects list:
AMERICAN LEAGUE EAST
Blue Jays: Hector Perez, RHP (No. 14) – 6 IP, 4 H, 2 R (1 ER), 2 BB, 5 K (Double-A New Hampshire)
Perez, a 22-year-old whom the Blue Jays acquired via a trade from the Astros last season, got off to a rocky start this season, but has given up one earned run in three straight starts and appears to be settling into a rhythm. Perez has excellent stuff, but his command has always been suspect and that's what's led to some of his struggles this season. The right-hander has walked 27 over 50 2/3 innings.

Orioles: Zac Lowther, LHP (No. 8) -- 6 IP, 2 H, 1 R, 3 BB, 8 K (Double-A Bowie)
Lowther took the loss for Bowie despite tossing six innings of one-run, two-hit ball. The 23-year-old southpaw allowed a leadoff double and a sacrifice fly in the first inning and issued three walks in the third inning before settling in and retiring nine of the final 10 batters he faced in what was his second straight quality start. Lowther has allowed one or fewer earned runs in seven of 10 starts this year en route to a 1.66 ERA that currently ranks third among Eastern League hurlers. He's posted 51 strikeouts against 23 walks in 54 1/3 innings so far this season while holding opposing hitters to a .191 clip.

Rays: Josh Lowe, OF (No. 15) -- 2-for-6, 2 HR, 3 RBI (Double-A Montgomery)
Lowe, a left-handed-hitting center fielder, led off the game with a homer and then added a two-run shot in the fourth inning -- both off of Birmingham lefty Kodi Medeiros -- as he recorded his second two-homer game of the season for the Biscuits. With the pair of dingers, the former first-rounder pick (2016) pushed his season total to a career-high nine home runs through 46 games. He achieved his previous high-water mark in 2017 during his first full season, when he went deep eight times in 118 games for Class A Bowling Green. Altogether, the 21-year-old Lowe is hitting .237 with 19 extra-base hits and 10 steals in his first Double-A campaign.
Rays prospects stats »
Red Sox: Bobby Dalbec, 3B (No. 2) -- 2-for-4, 2 HR, 2 RBI (Double-A Portland)
It's starting to seem like every time Dalbec steps to the plate, he hits a homer. The 23-year-old has homered four times over the past two games and has 12 homers through 49 games. Of course, Dalbec, whom the Red Sox selected in the fourth round of the 2016 Draft, is no stranger to hitting homers as he's coming off a 32 homer campaign in 2018. After going deep just twice in April, Dalbec hit .279 with eight homers in May and is clearly off to a fast start in June.
Red Sox prospects stats »
Yankees: Garrett Whitlock, RHP (No. 16) -- 6 IP, 5 H, 1 R, 1 BB, 5 K (Double-A Trenton)
After a series of shaky starts to close out the month of May, Whitlock kicked off June by recording his first win since April 19 on Saturday by tossing six innings of one-run ball versus Harrisburg. The 22-year-old, the Yankees' 18th-round pick in 2017, has completed six innings in four of nine starts this season, pitching to a 3.27 ERA in 41 1/3 innings overall. Whitlock, a 6-foot-5 righty, was one of the Minors' top breakout prospects last year, when he posted a 1.86 ERA with 122 strikeouts in 120 2/3 innings while ascending from Class A Charleston to Trenton.

AMERICAN LEAGUE CENTRAL
Indians: Bobby Bradley, 1B (No. 6) -- 4-for-4, HR, 4 RBI; Daniel Johnson, OF (No. 22) -- 3-for-5, 2 3B, 2B, 3 R (Triple-A Columbus)
The pair of Indians prospects combined for seven of the Clippers' 10 hits, three of which went for extra bases, in a loss against Durham. Bradley, 22, blasted a three-run homer and matched his season high in hits as part of a perfect night at the plate in the first game of a doubleheader. To go along with his International League-leading 16 home runs, Bradley has produced a 2.91/.359/.619 line over 50 games in his first Triple-A campaign. As for the Johnson, the 23-year-old is hitting .333/.372/.641 with eight extra-base hits in nine games since he was promoted to Columbus. Acquired from the Nationals in the offseason Yan Gomes trade, he opened the season by posting an .872 OPS with 10 homers over 39 games at Double-A Akron. Both Bradley and Johnson went 0-for-4 with a pair of strikeouts in the nightcap.
Indians prospects stats »
Royals: Meibrys Viloria, C (No. 18) -- 4-for-5, 2 2B, 3 RBI, 2 R (Double-A Northwest Arkansas)
Viloria set a season high with four hits and now has hits in four of his past five games, picking up the pace from a sluggish start to the season. The 22-year-old is hitting just .214 this season, his first at the Double-A level, but he did hit .257 in May so things are trending up a bit. While the 2019 season is Viloria's first taste of Double-A competition, he does have a bit of experience at the highest level as he appeared in 10 games with the Royals last year and went 7-for-27.
Royals prospects stats »
Tigers: Tarik Skubal, LHP (No. 18) -- 5 IP, 3 H, 0 R, 2 BB, 8 K (Class A Adv Lakeland)
Skubal, a ninth-round pick from the 2018 Draft, pitched out of the stretch in four of his five innings, but he was equally effective with runners on base and wound up spinning his second scoreless start of the year. Skubal threw 88 pitches, 60 strikes, and picked up his first win since May 5. The 22-year-old has thrown well in his full-season debut and has 64 strikeouts compared to 14 walks.
Tigers prospects stats »
Twins: Alex Kirilloff, OF (No. 2, MLB No. 12) -- 3-for-3, HR, 2B, 2 RBI, BB (Double-A Pensacola)
The 21-year-old turned in perhaps his finest offensive performance of the season, as he doubled in his first trip to the plate and connected on a two-run homer in the next, with both hits coming against lefty Kyle Muller (Braves' No. 11). He's hit both of his home runs this season in his last 10 games and owns a .351 average in that span. Overall, Kirilloff, one of the premier hitters in the Minors, has produced a .262/.358/.402 line in 28 games in his first Double-A campaign after missing all of April while recovering from a wrist injury.
Twins prospects stats »
White Sox: Luis Robert, OF (No. 2, MLB No. 18) -- 3-for-5, 3B, 2 RBI, R (Double-A Birmingham)
Robert extended his hitting streak to 10 games and boosted his average to .324 through 27 games with Birmingham. Of course, that comes after he hit .453 over 19 games with Class A Advanced Winston-Salem. Long story short, Robert has been on fire all year and has shown no signs of slowing down. The White Sox have been excited about Robert since signing him in 2017, but injuries have kept him off the field. Now that he's healthy for an extended period of time it's easy to see why Robert signed for $26 million.
White Sox prospects stats »
AMERICAN LEAGUE WEST
A’s: Luis Barrera, OF (No. 13) -- 4-for-4, 2 2B, RBI, R, BB (Double-A Midland)
Barrera is 6-for-8 over the past two games with a trio of doubles and three RBIs. The 23-year-old is hitting .280 through 33 games with Midland after he hit .328 over 36 games with the RockHounds to finish the 2018 campaign. The A's signed Barrera in 2012, but he didn't reach full-season ball until 2016.
A's prospects stats »
Angels: Brandon Marsh, OF (No. 3) -- 3-for-4, 2 3B, RBI, R (Double-A Mobile)
Make that three straight multihit performances for Marsh, who is hitting .292 this season, but left Mobile's game with an apparent leg injury. The 2016 Draft pick (second round) hit .266 over 127 games across two levels of A Ball last season.
Angels prospects stats »
Astros: Jose Hernandez-Urquidy, RHP (No. 30) -- 5 1/3 IP, 2 H, 1 R, 4 BB, 5 K (Triple-A Round Rock)
Hernandez-Urquidy threw a season-high 100 pitches, 60 strikes, but also walked four, another season high. However, the 24-year-old did find a way to limit the damage and only surrendered the one run. The right-hander, whom the Astros signed in 2015, began the year with Double-A Corpus Christi, but after going 2-0 with a 4.09 ERA over 33 innings, he was bumped up to Round Rock, where he has pitched to a 4.12 ERA in 19 2/3 innings.
Astros prospects stats »
Mariners: Jarred Kelenic, OF (No. 2, No. 42 in MLB) -- 2-for-5 (Class A Advanced Modesto)
Kelenic has hits in all three games with the Nuts since being promoted from Class A West Virginia.The 19-year-old, a first-round pick whom the Mariners acquired via an offseason trade with the Mets, hit .309 through 50 games with West Virginia. Kelenic has also shown some impressive pop this year and has already gone deep 13 times in 53 games.
Mariners prospects stats »
Rangers: Julio Pablo Martinez, OF (No. 4) -- 1-for-3, HR, 2 R, BB (Class A Adv Down East)
Martinez's solo shot in the second inning was his second homer in as many games and his fourth in his past seven contests. With six homers in 48 games so far this season, the 23-year-old, whom Texas signed for $2.8 million in March 2018, is quickly approaching his career-high home run total of nine, which he achieved over 67 games last season. It's still been a disappointing season thus far for the Cuban outfielder, who's hitting .185/.241/.354 through 48 games.
Rangers prospects stats »
NATIONAL LEAGUE EAST
Braves: Drew Waters, ATL (No. 5) -- 4-for-5, 2B, 2 3B, RBI (Double-A Mississippi)
Waters leads the Southern League with six triples after putting his 60-grade speed on display with a trio of extra-base hits in Mississippi's win over Pensacola. Waters, a 2017 second-rounder, is competing at the Double-A level for the first time, but has adjusted well, despite being just 20-year-old. Waters is in the middle of a nine-game hitting streak and is hitting .313 through 52 games. A season ago Waters hit .293 over two levels.
Braves prospects stats »
Marlins: Isan Diaz, 2B (No. 6) -- 2-for-4, HR, 3B, 2 RBI, 2 R (Triple-A New Orleans)
Diaz tallied New Orleans' only two extra-base hits on Saturday, as he put the Baby Cakes on the board in the first inning with a solo homer, his 11th of the season, and added an RBI triple in the eighth. The 22-year-old second baseman kicked off June on a high note after a torrid month of May in which he slashed .323/.427/.616 with eight homers in 29 games. After finishing the season's first month with a .226/.301/.344 batting line, Diaz now owns a .281/.371/.510 line through 54 games.
Marlins prospects stats »
Mets: Freddy Valdez, OF (No. 13) -- 2-for-4, HR, BB (Dominican Summer League)
Signed by the Mets in July of 2018 for $1.45 million, Valdez made his organization debut Saturday on the first day of play in the DSL, picking up his first homer in the process. His power is his best tool, so it is encouraging to see him clearing the fences in his first live action in the New York system. The 17-year-old is already well over 6 feet tall and is listed at 212 pounds, so there's certainly plenty of room to turn size and strength into in-game power as he matures.
Mets prospects stats »
Phillies: Adonis Medina, RHP (No. 2, MLB No. 68) -- 5 2/3 IP, 2 H, 1 R, 3 BB, 3 K (Double-A Reading)
Medina has definitely found his rhythm after a tough stretch in late April and early May during which he allowed 12 earned runs across three starts that all fell shy of 5 innings. Since then, he's rattled off three straight gems, allowing 2 combined earned runs over 15 2/3 innings. Saturday was Medina's first time getting an out in the sixth inning in 2019, and was also his busiest outing in terms of pitches thrown (91). The 22-year-old is making his Double-A debut this year and is off to a decent start, although his strikeouts are down and his walks are up relative to his time at lower levels.
Phillies prospects stats »
Nationals: Joan Adon, RHP (No. 21) -- 5 2/3 IP, 3 H, 1 R, 2 BB, 3 K (Class A Hagerstown)
Adon earned in the win in a nail-biting pitchers' duel as the Suns took down the Rome Braves 2-1. Adon is now 4-2 on the season, and while he's not posting gaudy strikeout numbers (only 42 in 50 1/3 innings, down from his previous seasons during which he was a hard-throwing reliever), he is keeping runs from crossing the plate. He has a 2.86 ERA on the season, which ranks among the 10 best in the South Atlantic League, and his groundball rate is way up from previous seasons. His new approach could be the key to retaining a role as a starting pitcher rather than returning to the bullpen.
Nationals prospects stats »
NATIONAL LEAGUE CENTRAL
Brewers: Aaron Ashby, LHP (No. 9) -- 6 IP, 4 H, 1 R, 3 BB, 7 K (Class A Wisconsin)
Ashby turned in his fifth quality start in his past six outings for the Timber Rattlers, but picked up a very unlucky loss to drop his record on the season to 3-3. That certainly does not represent his contributions to Milwuakee's Midwest League affiliate, as he's posted a 3.40 ERA with 67 strikeouts in 53 innings pitched. The nephew of 14-year MLBer Andy, Aaron is in his second year in the Brewers' organization after he was selected in the fourth round of the 2018 Draft.
Brewers prospects stats »
Cubs: Adbert Alzolay, RHP (No. 4) -- 6 IP, 1 H, 0 R, 1 BB, 8 K (Triple-A Iowa)
Alzolay, 24, was lights-out as he retired the final 16 batters while facing two over the minimum over six one-hit frames. After missing all of April and then struggling in his first two turns of the season for Iowa, the Venezuelan right-hander has now allowed two earned runs over his last 17 innings (three starts) while posting 23 strikeouts against two walks. Alzolay reached Triple-A for the first time in 2018 but logged only eight starts at the level before he suffered a season-ending lat injury.
Cubs prospects stats »
Cardinals: Dylan Carlson, OF (No. 6) -- 2-for-3, HR, 2B, 2 RBI, 3 R, BB (Double-A Springfield)
The 20-year-old switch-hitter took Royals top prospect Brady Singer (making his Double-A debut) deep in the fourth inning for his ninth home run of the season. He later added a double and also reached once via a walk in the contest while scoring three of Springfield's five runs out of the leadoff spot. The 2016 first-rounder is enjoying a breakout campaign in the Texas League, with a .302 average (.936 OPS), 27 extra-base hits and 10 steals through 51 games.
Cardinals prospects stats »
Pirates: Jason Martin, OF (No. 10) – 1-for-5, solo HR, 2 R (Triple-A Indianapolis)
Martin swatted his second homer in three games for the Indians, bringing him to 5 in 26 games this season. He spent some time with the big league club earlier this year, failing to hit a homer in his time with the Pirates, but he's found his power again back at Triple-A. However, he's only batting .243 so far in the Minors, which would be a career-low for the 23-year-old. He is showing signs of heating up, however, with hits in four of his past five games, including four extra-base hits, and seven runs scored.
Pirates prospects stats »
Reds: Vladimir Gutierrez, RHP (No. 8) -- 6 IP, 2 H, 1 R, 2 BB, 4 K (Triple-A Louisville)
The 23-year-old out of Cuba allowed two hits, one of which was a solo homer in the second inning, before retiring 15 of the final 17 batters he faced in a no-decision against Norfolk. It was arguably the best start of 2019 for Gutierrez, and the 6-foot right-hander has now completed six innings in four of his last five turns for the Bats. For the season, he has a 7.64 ERA in 53 innings (11 starts).
Reds prospects stats »
NATIONAL LEAGUE WEST
D-backs: Matt Tabor, RHP (No. 13) -- 5 IP, 3 H, 2 R, 1 BB, 8 K (Class A Kane County)
The D-backs' third-round pick in the 2017 Draft, Tabor, a product of the New England prep ranks, racked up a career-high in strikeouts over five innings against Clinton en route to his first full-season victory. The 20-year-old has picked up in 2019 where he left last season, when he posted a 3.26 ERA over 14 starts in the Class A Short Season Northwest League. Now pitching in the Midwest League, Tabor, through 24 innings (six starts), sports a 2.63 ERA, 0.88 WHIP and 29/4 K/BB.
D-backs prospects stats »
Dodgers: Mitchell White, RHP (No. 8) -- 5 2/3 IP, 4 H, 1 R, 3 BB, 9 K (Triple-A Oklahoma City)
White matched his season high in strikeouts as he recorded his first win in his fourth Triple-A start. The only run that the 24-year-old righty allowed came via a solo home run in the third inning, as he otherwise allowed just three singles while throwing 57 of 94 pitches for strikes in the outing. The 2016 second-rounder out of Santa Clara received a promotion to the Minors' highest level after he posted a 2.10 ERA with 37 strikeouts in 30 innings (seven starts) during his return to the Double-A Texas League.
Dodgers prospects stats »
Giants: Jake Wong, RHP (No. 7) -- 6 IP, 3 H, 2 R, 3 BB, 6 K (Class A Adv San Jose)
Wong, 22, posted his second quality start (both victories) in three turns since he was promoted to the California League. The 2018 third-rounder struck out six, matching his season high, and he's now completed exactly six innings all but once in his past eight starts across two levels. He's made 11 starts overall this season, pitching to a 2.54 ERA with 50/16 K/BB and a .197 opponents' average in 56 2/3 innings.
Giants prospects stats »
Padres: Luis Urias, INF (No. 3, MLB No. 24) -- 4-for-6, HR, 2 2B, 4 RBI, 3 R, BB (Triple-A El Paso)
Batting second and playing shortstop, Urias doubled in the first and third innings and had an RBI single in the seventh before connecting on three-run homer in his final at-bat to finish with a season-high four hits. The 21-year-old is crushing the ball in the Pacific Coast League, with a .367 average (1.203 OPS), 14 homers and 11 doubles through 40 games. He had a two-week stint with the Padres earlier this season, but was optioned back to Triple-A after hitting .083 while appearing in parts of 11 games.
Padres prospects stats »
Rockies: Daniel Montana, OF (No. 18) -- 3-for-5, 2 2B, RBI, R, BB (Class A Asheville)
Montano, 20, extended his hitting streak to five games with his second straight multihit performance. He hit a pair of doubles and matched his season high in hits. Signed for $2 million in July 2015, the Venezuelan outfielder is hitting .241/.306/.351 through 49 games in his full-season debut.
