Pirates prospects lead Solar Sox to win

Grossman collects three hits, Cunningham delivers two-run double

The Pirates' two-man contingent appeared to be all Mesa needed for victory on Thursday afternoon.

Thanks to a three-hit game from Robbie Grossman and a timely two-run double by Jarek Cunningham -- and late help from a pair of White Sox prospects -- the Solar Sox beat the Peoria Javelinas, 6-3.

Grossman, the Pirates' sixth-round draftee in 2008, doubled, singled twice and drew a base on balls in his six plate appearances. He is batting .325 through nine AFL games after completing his best season as a pro at Class A Advanced Bradenton. He registered career highs in batting (.294), homers (13) and RBIs (56).

Tyler Saladino (White Sox) plated Grossman, and Cunningham doubled home Saladino and Brandon Short (White Sox) during Mesa's game-deciding three-run fifth frame.

Saladino also tripled home Short for a seventh-inning insurance run. Both are members of Chicago's Top 10 prospects, and they went a combined 6-for-9 at the plate.

Making his second pro appearance, Peoria starter Danny Hultzen allowed a run on six hits -- including a first-inning RBI single by Josh Vitters (Cubs) -- over three innings. The Mariners' first-round draftee threw 63 pitches.

Solar Sox counterpart Trey McNutt, the Cubs' No. 4 prospect, yielded two runs on two hits over two innings. McNutt walked three batters and threw 53 pitches.

The host Javelinas (5-4), which relied on Brewers' farmhands in Wednesday's victory, had won three straight games while the Solar Sox climbed to 2-7 overall.
