Records broken, tied
The Aberdeen IronBirds had no problems at the plate Thursday night, pounding out 17 hits and double-digit runs in a 14-4 win over Vermont at Ripken Stadium.
At the forefront of Aberdeen's powerful offensive display was Jonathan Schoop, who set a new, single-game club record by knocking in seven RBIs. The second baseman, who is in Aberdeen on a rehab assignment after injuring himself while playing with the Class-AAA Norfolk Tides, struck first in the sixth inning, blasting a grand slam off the Vermont pitcher. In the eighth, Schoop hit his second homer of the game, this one a three-run shot that gave him seven RBIs for the evening. He finished the game 4-for-5 with two runs scored.
Also making his way into the IronBirds' record books was Jeff Kemp, who tied Aberdeen's single-game mark of four runs scored. Kemp went 3-for-4 with two doubles and two RBIs.
Schoop broke the record set by Danny Figueroa during the 2006 season, while Kemp tied a mark which is shared by Anthony Caronia, Ronnie Welty and Roderick Bernadina.
Aberdeen reliever Jose Figuereo (1-1) earned the win, going two innings in which he struck out a pair and held Vermont to one earned run on two hits.
Starter Sebastian Vader went four innings, striking out six, issuing two walks and allowing three earned runs on four hits in a no-decision.
