PITTSBURGH -- Lyle Overbay ruined manager Clint Hurdle's strategy with a two-run single that broke a tie and the Milwaukee Brewers went on to a 9-3 victory over the sloppy Pittsburgh Pirates on Saturday.

The struggling first baseman capped a three-run fourth inning and broke a 2-2 tie with his hit.

After left fielder Khris Davis hit an RBI single to tie the score, Hurdle intentionally walked second baseman Scooter Gennett to load the bases with one out. However, the .213-hitting Overbay delivered.

Right fielder Ryan Braun put the game away for the Brewers by hitting a two-run double to cap a four-run eighth inning that made it 8-3. Shortstop Jean Segura added an RBI single during the inning and another run scored on a groundout. Pinch hitter Irving Falu added a sacrifice fly in the ninth.

Overbay's hit helped right-hander Matt Garza (4-4) win his second straight start. Garza gave up just three runs in six innings despite issuing five walks, allowing six hits and having only one strikeout.

Catcher Jonathan Lucroy and Davis had two hits each for the Brewers (37-26).

The Pirates (29-32), who committed five errors, got two hits each from second baseman Neil Walker and third baseman Pedro Alvarez.

Edinson Volquez (3-5) lost for the first time in four starts, giving up four runs (three earned) and four hits in six innings.

Alvarez's two-run single gave the Pirates a 2-1 lead in the third inning after Lucroy hit a sacrifice fly in the first inning.

After Overbay put Milwaukee ahead, Pittsburgh got within a run in the sixth, 4-3, on a double-play grounder. However, relievers Rob Wooten, Will Smith and Brandon Kintzler followed Garza with one scoreless inning each.

NOTES: Pirates RHP Charlie Morton and RHP Gerrit Cole might not make their scheduled starts Sunday against Milwaukee and Monday night against Chicago, as both have been experiencing shoulder discomfort. LHP Jeff Locke was scratched from his scheduled start Friday night for Triple-A Indianapolis and probably would take Morton's place. ... Pittsburgh LF Starling Marte was not in the starting lineup for the fourth straight game; he entered the day in an 0-for-20 slump. OF Jose Tabata started in his place. ... Milwaukee 1B Mark Reynolds' streak of 16 consecutive starts ended as he was rested in favor of 1B Lyle Overbay. ... Brewers rookie LHP Wei-Chung Wang suffered a bruised right knee Friday night when struck by a line drive, but X-rays were negative. ... Brewers LHP Tom Gorzelanny, rehabbing from offseason shoulder surgery, will pitch again Monday for Triple-A Nashville. Gorzelanny worked 2 1/3 scoreless innings Friday night against Memphis in the Pacific Coast League and manager Ron Roenicke said it was the best of the lefty's nine minor league appearances. ... The three-game series concludes Sunday with Milwaukee RHP Yovani Gallardo (3-4, 4.08) facing RHP Charlie Morton (2-7, 3.31).
