The Rockies play their final game before the break at home versus Philly Sunday. Colorado has taken two of three in this series so far, and I like the Rockies to take advantage of a mismatch on the mound here in Game 4. My money is on Colorado as a home favorite.

Here are my keys to the game:

1. Pitching - The Rockies send Tyler Chatwood to the mound, and he's having himself a solid season so far. Chatwood (8-4, 3.08 ERA) allowed just a pair of runs on three hits through five innings in a win at San Francisco in his last outing. The 26 year old is 2-0 with a 1.50 ERA in his last two starts versus Philly. The Phillies counter with rookie right-hander Zach Eflin who is making just his sixth career start.

2. Philly Bats - Only the Atlanta Braves have scored fewer runs in the major leagues in 2016 than Philadelphia. The Phillies team batting average of .243 is also among the worst in the majors.

3. X-Factor - Colorado is 6-1 in the last seven meetings in this series.

Selection: This is a play on the Colorado Rockies (8*)
