Phillies vs. Cardinals Prediction, Winner, Over/Under – Wednesday, August 12

Philadelphia held off St. Louis in Monday’s series opener, 6-5, highlighted by OF/IF Edmundo Sosa’s 3-RBI performance. The Phillies’ offense couldn’t get going against St. Louis P Andre Pallante last night, producing 5 total hits in their third shutout since the All-Star break.

The Cardinals improved to 9-15 dating back to July 18, as St. Louis sits 3.5 games behind the second-place trio in the Wild Card standings. Following today’s matinee, the Redbirds embark on a 10-game road trip, starting Friday at Wrigley Field against the rival Cubs.

St. Louis ranks fourth in MLB in xwOBA at .323, but the Cards are the only team in the top eight of xwOBA that owns a wRC+ of less than 100 (95).

Since Philadelphia was last shut out at Miami on July 28, the Phillies averaged 5.58 runs over a 12-game stretch before Tuesday’s defeat.
