Reliever Edubray Ramos faced two batters and walked them both to open the 11th, Casey Fien then entered and surrendered a two-run double to Stephen Piscotty. Yadier Molina followed with a two-run homer. Tommy Pham provided insurance with another two-run homer.
"Ramos didn’t record an out and he didn’t throw strikes,” said Phillies manager Pete Mackanin. ”Then we threw balls that were hit. It’s a tough way to lose a game after we had good pitching for 10 innings.”
The Phillies have won just once over the last two weeks and sit an abysmal 25 games below the .500 mark.
Jeremy Hellickson tossed seven innings for the Phillies for the first time since April 21, surrendering six hits - including a Jedd Gyorko solo homer in the second inning.
Philadelphia scored its lone run of the game on a Maikel Franco RBI single after Cardinals starter Mike Leake walked the first two batters in the fourth inning.
Prior to Ramos and Fien faltering in the 11th, Joaquin Benoit, Hector Neris and Pat Neshek combined on three scoreless innings for the Phillies.
The series continues Wednesday as the Phillies send rookie Nick Pivetta to the mound to oppose the Cardinals' Michael Wacha.
