Hoskins reclaimed the Minor League home run lead on Wednesday night when he connected on his 26th homer for Double-A Reading. After slugging 13 home runs over 27 games in June, the 23-year-old first baseman has cooled off in July, hitting .224 with four homers in his last 16 contests. All together, Hoskins has hit .279/.346/.561 through 91 games for Reading, while his 84 RBIs are tops among all Eastern League hitters.
In his last start for Double-A Trenton, Adams extended his hitless-innings streak to 11 before surrendering a leadoff double in the second inning -- the only hit he'd allow in the game. The 21-year-old righty went on to strike out eight while tossing six scoreless innings, giving him 16 straight scoreless frames entering the day. Adams has yet to lose a game this season, going 9-0 in 18 starts between Class A Advanced Tampa and Trenton, with a 2.45 ERA, a 0.89 WHIP and a 106-27 strikeout-to-walk ratio in 91 2/3 innings.
Kaminsky, 21, was at his best in his last start for Double-A Akron as he tossed a season-high 7 2/3 innings, allowing one earned run and striking out six against Erie. The southpaw has not allowed more than two earned runs in six straight starts, during which he's registered a 2.46 ERA in 36 2/3 innings.
Holmes scuffled to begin his season but has pitched well since the calendar flipped to June. The 23-year-old right-hander has gone 4-1 in eight starts for Altoona during that stretch, while posting a 3.38 ERA with 42 strikeouts in 45 1/3 innings.
