MINOR LEAGUE REPORT

TRIPLE-A NORFOLK

The top hitting prospects on the Tides are going through a minor power drought. First baseman Trey Mancini, who entered Friday batting .269 with a .782 OPS and six home runs for Norfolk, hadn’t homered since June 3. Left fielder Christian Walker, who went into the weekend batting .240 with nine homers and a .715 OPS, hadn’t homered since May 31. The two accounted for more than a third of Norfolk’s 42 home runs through 67 games.

DOUBLE-A BOWIE

Right-hander Jason Garcia lowered his ERA below 5.00 for the first time since mid-April after pitching six scoreless innings against Portland on Thursday night. Garcia, a Rule 5 draft selection who spent last season in the Orioles bullpen, returned to starting this year and has only recently found his stride. He’s pitched six scoreless innings in two of his past three starts. Garcia is 3-6 with a 4.95 ERA, with 32 strikeouts and 32 walks.

HIGH-A FREDERICK

Outfielder Conor Bierfeldt, 25, is back to his slugging ways this month with the Keys. Bierfeldt entered Saturday batting .283 with five home runs and 15 RBIs in June, bringing his season mark to .280 with seven home runs. His seven homers were second most on the team behind infielder Anderlin Rodriguez’s 10. The 2013 29th-round draft pick hit a dozen home runs in each of his first three professional seasons.

LOW-A DELMARVA

Orioles manager Buck Showalter singled out 19-year-old right-hander Ofelky Peralta for praise on the heels of a crackling performance in which he struck out seven and allowed one run on three hits in five innings Tuesday. The hard-throwing Peralta allowed more than two earned runs in just two of his first 12 starts this season, and entered the weekend with a 2.89 ERA and 55 strikeouts in 56 innings. — Jon Meoli
