The rest of the best performances from top prospects Wednesday
• Making his first career start in left field, No. 18 overall prospect Alex Bregman went 3-for-5 and scored one of Triple-A Fresno's eight runs in a win over Round Rock.

• No. 22 overall prospect Bradley Zimmer collected a season-high four hits as Double-A Akron knocked off Richmond, 7-3. The Indians' No. 1 prospect finished 4-for-5 at the plate and drove in a pair of runs in the contest.
• It was another multi-hit game for No. 40 overall prospect David Dahl (Rockies' No. 2), as he went 2-for-4 with a double for Triple-A Albuquerque in a loss against Nashville. The 22-year-old outfielder has hit safely all 13 games since being promoted, with a robust .510/.564/1.000 slash line and 12 extra-base hits in that span.
• No. 44 overall prospect Dominic Smith connected on his 12th home run to extended his hitting streak to seven games for Double-A Binghamton. During said streak, the Mets' No. 1 prospect is hitting .452 and has six multi-hit performances.
• No. 47 overall prospect Jake Thompson continued to roll as he fired six scoreless innings of three-hit ball to lead Triple-A Valley past Indianapolis. The Phillies' No. 2 prospect struck out five but also walked a season-high four batters, with 50 of his 90 pitches going for strikes. Since the beginning of June, Thompson, 22, has won six of his past nine starts while posting a stellar 0.58 ERA over 62 1/3 innings in that span. During that stretch, the 22-year-old righty has lowered his season ERA to 2.29 from 4.23.
• No. 50 overall prospect Gary Sanchez had himself an inning, going 2-for-2 with a grand slam in a 12-run sixth for Triple-A Scranton/Wilkes-Barre in a win against Charlotte. Sanchez finished the game 3-for-6 with four RBIs. The homer was the 10th of the season for the Yankees' No. 3 prospect, who is batting .282/.326/.482 through 62 games.
• No. 79 overall prospect Nick Gordon (Twins' No. 4 ) improved his batting average to .307 by going 4-for-5 at the plate in Class A Advanced Fort Myers' 13-10 loss to Lakeland.

• Dodgers No. 11 prospect Willie Calhoun connected on his 20th home run as part of a 1-for-3 performance for Double-A Tulsa. The 21-year-old second baseman has gone deep three times in his past two games and six times over his last 10.
• Cubs No. 16 prospect Eddy Martinez fell a single shy of hitting for the cycle, although it wasn't enough to keep Class A South Bend from falling to Burlington, 7-5. The 21-year-old outfielder's home run, a solo shot in the fourth inning, was his eighth of the year, and he also plated a pair of runs with a two-out triple in the eighth.
• Cardinals No. 16 prospect Austin Gomber hurled the first complete game of his career but was a tough-luck loser as Class A Advanced Palm Beach was shut out by Brevard County. The 6-foot-5 southpaw allowed one earned run on six hits and, for a second straight start, struck out eight batters. Overall, Gomber has pitched to a 2.87 ERA in 16 starts, while his 92 strikeouts rank second in the Florida State League.
