PITTSBURGH (AP) -- Matt Garza got through six shaky innings to win back-to-back starts for the first time since last July and Lyle Overbay hit a tiebreaking two-run single to lead the Milwaukee Brewers to a 9-3 win over the Pittsburgh Pirates on Saturday.
   Garza (4-4) allowed five walks and six hits while striking out one, yet limited the Pirates to three runs a day after they scored a season-high 15 against Milwaukee.
   Overbay delivered his hit in a three-run fourth inning that put the Brewers ahead 4-2.
   Davis and Jonathan Lucroy had two hits each for the NL Central-leading Brewers. Ryan Braun's two-run double in a four-run eighth inning extended Milwaukee's lead to 8-3.
   Neil Walker and Pedro Alvarez had two hits each for Pittsburgh.
   Edinson Volquez (3-5) lost for the first time in four starts, giving up four runs and four hits in six innings.
