Placido Polanco hit a tiebreaking, two-run double in the eighth inning to lift the Philadelphia Phillies to a 6-4 victory over the Chicago Cubs on Monday night.
Bryan LaHair hit a tying, two-run homer off Chad Qualls (1-0) in the eighth after Vance Worley threw seven impressive innings for Philadelphia.
But the Phillies answered in the bottom half. Scott Maine (0-1) hit pinch-hitter Juan Pierre with a one-out pitch and Jimmy Rollins singled off Rafael Dolis with two outs.
Polanco, who had just two RBIs in his first 71 at-bats, drove in two with a hard liner to the wall in left.
Jonathan Papelbon pitched the ninth for his eighth save in as many tries, giving Philadelphia a split of the four-game series.
The five-time defending NL East champion Phillies finished April at 11-12, their first losing record in a full month since going 11-15 in June 2009.
The bright side for the Phillies: They were only 12-10 in April 2010 and went on to win a major league-best 97 games.
