Oliver Perez tossed four scoreless innings in his first start this offseason with Culiacan in the Mexican Winter League.

Perez limited Mexicali to three hits, while striking out four and walking two, on Tuesday night. He allowed a pair of first-inning singles, but kept Mexicali off the scoreboard that frame. Then, in the second inning, Cory Aldridge had a leadoff double off Perez and moved to third with none out on a wild pitch, but was stranded there. Perez issued a pair of one-out walks in the fourth.

Perez had entered the winter-league game having allowed five earned runs in five relief innings, and having averaged two baserunners allowed per inning. He shaved his ERA from 9.00 to 5.00.
