It’s a battle between National League West foes on national TV Thursday night, as the Colorado Rockies host the Arizona Diamondbacks at 8:40 p.m. ET on FS1. The Diamondbacks are currently tied for third place in the NL West with the San Francisco Giants, as each squad is 10 games behind the first-place San Diego Padres. The Rockies, meanwhile, have MLB’s worst record at 32-88 and are 26.5 games back of the third-place Diamondbacks.

The Diamondbacks are rolling with lefty Eduardo Rodriguez, who has a disappointing 4-7 record and 5.68 ERA in his second season in Arizona after signing a 4-year, $80 million contract during the 2023 offseason. The Rockies are sending out Bradley Blalock, who is 1-3 with a 7.89 ERA in eight starts this season. In two August starts, Blalock has allowed 12 runs in 10.1 innings for an ugly 10.45 ERA. 

Rodriguez’s strikeout prop resides at 4.5 (Over -130, Under -102) at FanDuel Sportsbook, while Blalock’s is down at 2.5 (Over -136, Under +108). The SportsLine Projection Model’s top recommended pitching prop for this contest is Rodriguez Under 3.5 earned runs allowed (-133). The model projects him to surrender 2.6 earned runs tonight, making this a 4.5-star play (out of 5 stars). 

Five of the six shortest odds to hit a home run in this game belong to Diamondbacks, with Corbin Carroll (+210) and Ketel Marte (+290) leading the pack. The only Rockies player in that group is Hunter Goodman, who has the third-lowest odds to leave the yard at +320. 

The Diamondbacks are -173 road favorites to win (wager $173 to win $100) in the latest SportsLine consensus odds, while the Rockies are +145 (wager $100 to win $145) home underdogs. The total sits at 12 after it was first released at 12.5. You can find the model’s latest projections and expert picks for Diamondbacks-Rockies at SportsLine.
