The Colorado Rockies enter Sunday as losers of four straight including a pair of lopsided defeats here at Dodger Stadium. I think the Rockies will put up a better fight in the series finale today and possibly upset the Dodgers with a straight up win.

Here are my keys to the game:

1. Pitching - The Rockies hand the ball to Jon Gray (5-3, 4.83 ERA). He's done his best work outside of Coors Field and in the day this season. The right-hander has allowed four runs on four htis in 11 innings in two day starts with a .111 batting average against. The Dodgers counter with Brandon McCarthy who will make his season debut and first major-league appearance since April 25, 2015 due to Tommy John surgery. He allowed four runs (three earned) over five innings in a rehab start for High-A Rancho Cucamonga on Monday and he's 0-1 with a 4.61 ERA in four minor league starts this year.

2. Situational - The Rockies are 5-1 in their last six games after losing the first two games of a series and 10-3 in their last 13 Sunday games.

3. X-Factor - Colorado's Carlos Gonzalez is batting .427 in 21 at bats over the last seven days. He's 4-for-11 in previous meetings with McCarthy and Charlie Blackmon is 4-for-8 off the 32 year old.

Selection: This is a play on the Colorado Rockies +1.5 (8*)
