(WNFL)- Milwaukee Brewers' starter Matt Garza will pitch against one of his old teams tonight, when the Crew hosts the Chicago Cubs to open a three-game weekend series. Garza is 0-and-2 with an ERA of four-and-a-half. The veteran right-hander is coming off three shaky starts in which opponents batted .329 against him. That was after Garza surrendered just two hits in eight innings of his Milwaukee debut on April second. Brewers' manager Ron Roenicke says Garza changes from outing-to-outing but in his words, "The more we see him, the more we'll understand." Garza started 60 games for the Cubs before he was traded to Texas last July. He was 21-and-18 in those starts, with a three-point-four-five E-R-A. Roenicke said he knew that when Garza was in a groove in those days, Milwaukee was not going to get off easy. Tonight, ex-Brewer Carlos Villanueva takes the mound for Chicago. He's 1-and-4 with a ten-point-nine-three ERA. Villanueva gave up five runs in four-and-two-thirds innings last Sunday against Cincinnati, and he gave up nine runs in three-plus frames before that. The Cubs have a four-game road losing streak. Milwaukee is coming off a home series against San Diego in which they took 2-of-3.
