ST. LOUIS (Interstat) — Shane Drohan pitched six innings of one-run ball and David Hamilton delivered a two-run double in a four-run seventh inning as Milwaukee topped St. Louis 4-3 on Monday at Busch Stadium III before 21,786 fans.

The Brewers trailed 3-0 entering the seventh after St. Louis scored twice in the third on Nelson Velázquez’s forceout and José Fermín’s RBI single, then added a run in the sixth on Masyn Winn’s single. Milwaukee erupted in the seventh off Ryan Fernandez: Hamilton doubled to left-center, scoring Garrett Mitchell and Sal Frelick, and Brice Turang followed with a two-run single.

Drohan (4-2) allowed six hits, struck out two and walked none over six innings for the win. Trevor Megill worked a scoreless ninth for his 14th save. Dustin May struck out seven over 4 2/3 scoreless innings for St. Louis.

Milwaukee (56-33) has won five of its last seven. St. Louis (47-41) lost for the second time in three games. The teams meet again Tuesday in a doubleheader.
