MILWAUKEE (AP) — Gio Gonzalez pitched six smooth innings on his 33rd birthday and Jesus Aguilar hit a three-run homer in the Milwaukee Brewers’ 7-0 victory over the Cincinnati Reds on Wednesday night.

Manny Pina also had a three-run shot and Aguilar finished with four RBIs. Gonzalez’s stellar showing helped the Brewers boost their lead for the top NL wild card to three games over St. Louis, which lost to Atlanta earlier.

The Brewers began the day trailing the first-place Cubs by 3½ games in the NL Central. Chicago played later at Arizona.

Reds right-hander Matt Harvey (7-9), a pitcher the Brewers nearly acquired a few weeks ago before a proposed deal fell through, gave up Aguilar’s game-changing home run.
