Robles celebrates birthday with big game for Potomac

Nationals No. 1 prospect (No. 5 overall) Victor Robles had a 20th birthday to remember on Friday, going 4-for-5 with a triple and a two-run homer in Class A Advanced Potomac's 11-7 loss to Lynchburg. Robles raised his season average by 28 points with the performance to .283.

"We got off to a rough start tonight and got down a bunch, but he goes out and hits an opposite-field homer and then the triple," Potomac manager Tripp Keister told "When he hit it, you really didn't think he'd get three out of it, but he's so fast and does so many things that make you say, 'Wow.'"

The rest of the best performances from top prospects Friday:

Gleyber Torres (Yankees' No. 1, No. 2 overall) blasted a grand slam to help lift Double-A Trenton to a 6-0 win over Portland. It was Torres' fifth homer in 30 games this season, and the 20-year-old shortstop is now slugging .513 in his first taste of Double-A ball.

Michael Kopech (White Sox No. 3, No. 13 overall) turned in another strong start, allowing one run on three hits over seven innings, walking two and striking out eight for Double-A Birmingham in a 3-1 victory over Tennessee. The flamethrowing 21-year-old right-hander has racked up 59 strikeouts in 42 1/3 innings pitched.

• Willie Calhoun (Dodgers' No. 4, No. 74 overall) belted his third homer in as many games in Triple-A Oklahoma City's 7-6 loss to El Paso. The 22-year-old second baseman is batting .319 with eight homers and a .570 slugging percentage through 36 games.

• Christin Stewart (Tigers' No. 2) tied the Minor League lead in homers in grand fashion, blasting a grand slam for his 12th home run of the season in Double-A Erie's 11-10 loss to Altoona. The 23-year-old outfielder has doubled his home run total from Double-A in 2016 in just 14 additional games this season.

• Rowdy Tellez (Blue Jays' No. 5) hit a walk-off homer in the 13th inning to send Triple-A Buffalo to a 7-5 win over Pawtucket. Tellez was 2-for-7 in the game, and the 22-year-old's game-winning shot was his fourth homer of the season.

Connor Sadzeck (Rangers' No. 10) tossed eight strong frames for Double-A Frisco in a 2-1 loss to Corpus Christi. The 25-year-old right-hander yielded just one run on three hits, walking one and fanning nine in his best outing of the season, lowering his ERA by more than half a run in the process to 4.34.

• Yu-Cheng Chang (Indians' No. 11) hit two solo homers for Double-A Akron in an 8-7 loss to Hartford. The 21-year-old infielder is hitting just .197 so far in 2017, but he now has nine homers in his first 33 games at the Double-A level.

• Scott Kingery (Phillies' No. 11) had a huge game for Double-A Reading, hitting a two-run homer in the fourth inning and then a walk-off shot in the 10th for a 7-6 victory over New Hampshire. The 23-year-old second baseman, selected by Philadelphia in the second round of the 2015 Draft, is slugging .622 with 11 round-trippers in 35 games for the Fightin Phils.

• Tony Santillan (Reds' No. 14) flirted with perfection for Class A Dayton. The right-hander cruised through six innings without allowing a baserunner before finally giving up a pair of harmless singles with one out in the seventh. Santillan erased both and ended the night with a line of seven innings, five strikeouts and just the two hits allowed. A second-round pick in 2015, the 20-year-old now holds a 2.76 ERA in nine starts this year after posting a 5.19 mark across two levels last season and a 5.03 ERA in his rookie debut.
