Watch And Listen Online Rockies Vs. Diamondbacks LIVE Stream At 9:40: First Place In Division On The Line

Watch and listen online Rockies vs. Diamondbacks LIVE stream at 9:40 EST: The 8-4, 3.09 ERA of Jorge De La Rosa will be on the hill for Colorado as it attempts to take down the top of the AL-West divisional-rival Arizona Diamonbacks.

Watch and listen online Rockies vs. Diamondbacks LIVE stream: On the hill for Arizona is Tyler Skaggs. He's being called up to make the start for Trevor Cahill.

Watch and listen online Rockies vs. Diamondbacks LIVE stream: Skaggs had 13 strikeouts in his last outing in Triple-A, but the former number one overall pick will make his return to the big leagues.

"He'll have a better idea of what he's up against," D-backs manager Kirk Gibson told MLB.com. "We're going to play a good Colorado team, and they're going to score a lot of runs, so he's going to have to make good pitches on them. Hopefully he has an understanding of that and is able to execute."

The Rockies are 2 1/2 games out of first. This three-game series could be an opportunity for a new team to be in first place of the division.

De La Rosa is battling a thumb injury that keeps coming back.

"It's popped up here a few times in a row, so we'll keep an eye on it," Rockies manager Walt Weiss told MLB.com. "It's funny because in between starts it seems to be fine, then once he starts warming up in the bullpen is when he starts to feel it again and we're going inning to inning with him during the game."
