SCOTTSDALE, Ariz. -- 28-year-old Curtis Partch yielded four hits and six runs (three earned runs) in 1.2 innings as the Giants lost 12-2 to the D'Backs in split-squad action on Sunday.
Jeremy Hellickson, acquired in a trade last November with Tampa Bay, allowed one hit with a strikeout over two innings during his Diamondbacks debut.
Arizona struck for five runs in the fourth inning, starting with a leadoff triple by Gerald Laird. Four of the runs came with two outs, helped by an error and a passed ball.
Peralta, a regular in the Diamondbacks' outfield the second half of last season, had two hits. He's trying to keep his place on the major league roster as a starter or reserve.
