The rest of the best performances from top prospects Saturday
• No. 27 overall prospect Aaron Judge homered for a third straight game as Triple-A Scranton/Wilkes-Barre fell to Pawtucket, 7-3. The Yankees' No. 2 prospect has gone deep six times in his past seven games, giving him 15 homers in 71 games for the season.
• No. 36 overall prospect Francis Martes fired seven scoreless innings to pace Double-A Corpus Christi in a 3-0 shutout of Frisco. The Astros' No. 3 prospect allowed three hits, walked one and struck out five in the outing, with 60 of his 90 pitches going for strikes. Martes, 20, has been especially sharp of late, posting a 1.48 ERA with 30 strikeouts over 30 1/3 innings this month.
• In his first start since coming off the disabled list, No. 38 overall prospect Brent Honeywell (Rays' No. 2) tossed five innings of one-run ball in Class A Advanced Charlotte's loss to Bradenton. The 21-year-old righty, who landed on the DL with right arm tenderness on May 20, allowed three hits and a walk and struck out four.
• No. 46 overall prospect Dominic Smith (Mets' No. 1) delivered a go-ahead three-run homer in the bottom of the seventh inning in Double-A Binghamton's 4-3 win against Richmond. The 21-year-old first baseman has homered in back-to-back contests for the B-Mets and has six in 69 games for the season, matching the career-high total he achieved over 118 games in 2015.
• No. 65 overall prospect Kyle Tucker went 2-for-5 and hit his second home run of the season -- a three-run shot off of Marcos Diplan (Brewers' No. 19) -- to lead Class A Quad Cities past Wisconsin, 8-4. On the year, the Astros' No. 4 prospect is hitting .304 with 18 extra-base hits and 25 steals.
• No. 67 overall prospect Ian Happ blasted his first Double-A home run in Tennessee's loss against Pensacola. The Cubs' No. 3 prospect finished 3-for-4 at the plate and has collected exactly three hits in two of three games since joining the Smokies. Prior to his promotion, Happ batted .296/.410/.475 with 26 extra-base hits, 42 RBIs and 10 steals at Class A Advanced Myrtle Beach.
• In the same game that Kyle Tucker went 2-for-5 with his second homer, No. 74 overall prospect and fellow 2015 first-rounder Trent Clark (Brewers' No. 5) generated the same exact line for Class A Wisconsin. Shortstop Isan Diaz (Brewers' No. 11) also had a big game for the Timber Rattlers, going 3-for-4 with a two-run home run and a double. The 20-year-old is hitting .247 with eight homers and 19 doubles this season.
• Making his first pro start since July 2014, No. 76 overall prospect Hunter Harvey (Orioles' No. 1) struck out five of the seven hitters he faced over two scoreless innings for the Orioles' Gulf Coast League affiliate. The 21-year-old righty, whom the Orioles selected in the first round of the 2013 Draft, began the season on the disabled list after he suffered a groin strain during an intrasquad camp game in late March. In early May, he was forced to undergo surgery for a sports hernia, costing him another 4-6 weeks.
• Cubs No. 10 prospect Eloy Jimenez hit a monster three-run home run, his 10th of the season, in Class A South Bend's shutout of Dayton. The 19-year-old outfielder is putting up impressive numbers in his full-season debut, hitting .337/.376/.548 with 36 extra-base hits and 52 RBIs through 68 games.
• Marlins No. 17 prospect Chris Paddack dominated yet again with his third straight no-hit start for Class A Greensboro. The 20-year-old right-hander struck out nine and hit a pair of batters in the outing, which he needed just 60 pitches (42 strikes) to complete. With his performance on Saturday, Paddack has now thrown 15 consecutive hitless innings during which he's piled up 28 strikeouts against one walk.
• Padres No. 10 prospect Dinelson Lamet turned in his best start since being promoted to Double-A, tossing six scoreless innings of one-hit ball in San Antonio's 16-0 rout of Midland. The 6-foot-4 righty struggled with his control as he walked five and threw just 54 of his 93 pitches for strikes, but he was able to offset those baserunners by striking out nine, matching his season-high, and generating another five outs on the ground. In 16 starts between the Class A Advanced and Double-A level, Lamet, 23, has pitched to a 2.83 ERA with 78 strikeouts in 86 innings.
