Chicago at Colorado

The Cubs turn to Jake Arrieta (4-1, 4.63 ERA), who has pitched better than the ERA might suggest, with a 41-9 strikeout to walk ratio in 35 innings. They face a Colorado team that has improved its pitching depth and defense, and is #11 in baseball in fielding. Colorado is 19-9 UNDER the total in home games, including 14-6 UNDER at Coors Field against a righty starter. 22-year-old Rockies righty Antonio Senzatela (4-1, 2.84 ERA) has been impressive with a 2-1 record and a 3.15 ERA in three home starts. The Rockies are 11-4 UNDER the total when their opponent allows five runs or more in their previous game. Play Game 1 of today's doubleheader to finish UNDER the total.
