The St. Louis Cardinals have out-scored the Phillies 25-5 through the first two games of this series at Citizen's Bank Park, and we should see a similar result here in the series finale on Sunday. The Phillies send a rookie pitcher to the mound, and that could spell disaster against the hot St. Louis bats.

Here are my keys to the game:

1. Pitching - The Cardinals send Michael Wacha to the mound in search of his 10th win of the season. Wacha (9-2, 2.48 ERA) gave up two runs on three hits in 6.1 innings in a win over the Twins in his last start. He's 6-1 with a 2.08 ERA in eight start on the road this season. The Phillies counter with 25 year old rookie Adam Morgan, who was win-less with a 4.74 ERA in 13 starts at Triple-A.

2. Phillies Bats - Philadelphia has scored a major league worst 211 runs so far, and the Phillies have been shutout three times while losing 11 of their last 12 overall.

3. X-Factor - The Cardinals have won five straight in this series, and they've out-scored the Phillies 47-15 in those games.

Selection: This is a play on the St. Louis Cardinals -1.5 (8*)
