An intriguing National League West duel is only one of a 17-game slate in the MLB on Saturday, August 6, so make sure you don’t miss the best Rockies vs. Diamondbacks betting pick and odds.

Colorado and Arizona will play the second of three games in this series at Chase Field, and the Diamondbacks are -170 moneyline favorites on BetOnline Sportsbook. Prior to this series, these divisional rivals have met ten times this season, and the Rockies lead 6-4.

Rockies managed to avoid the sweep against the Padres

The Colorado Rockies lost the opening four games of a five-game series against the San Diego Padres on the road, but managed to win the final tilt and avoid the series sweep. Colorado snapped a five-game losing streak in the process and now will face Arizona on the road before returning home to take on the Cardinals and D-Backs.

Ryan McMahon was in the zone in a 7-3 victory over the Padres as he hit a home run and drove in five RBIs, which is easily his best game of the season. Kyle Freeland recorded his third consecutive win and improved to a 7-7 record after allowing two runs on six hits with seven strikeouts and four walks in 5.2 innings.

Antonio Senzatela (3-6) is looking for his first victory since June 19 as he gets his 17th start of the year. The 27-year-old right-hander currently has a 4.87 ERA, 1.71 WHIP, and a 48/20 K/BB ratio in 77.2 innings. Senzatela was dismantled in his lone start against the D-Backs this season, registering a 13.50 ERA in 2.0 innings.

Diamondbacks returned to losing ways

Although they ended a four-game losing run with a win over the Cleveland Guardians, the Arizona Diamondbacks lost the next game to the Guardians and lost the series 2-1. They spent the last six games on the road and now will play the next seven at Chase Field. Arizona will be looking to stay above the Rockies in the standings after this series in the desert.

Tommy Henry suffered a loss in his first-ever start in the MLB as he surrendered four runs on four hits with three strikeouts and three walks in 5.0 innings. Alek Thomas and Geraldo Perdomo chipped in offensively with a two-run homer apiece, but Arizona lost 7-4.

Merrill Kelly (10-5) will start on the mound for the 22nd start of the season when he takes on the Rockies on Saturday. The 33-year-old righty experienced a fantastic month of July and recorded four wins in six starts (two no-decisions) with a great 1.31 ERA. For the year, Kelly has a pristine 2.87 ERA, 1.13 WHIP, and a 104/38 K/BB ratio in 125.1 innings of work.



  • 1-5 in the last six overall
  • 1-5 in the last six vs. National League West rivals
  • 2-8 in the last ten games vs. a right-handed starter


  • 4-0 in the last four home games with the total set at 7.0-8.5
  • 5-1 in the last six home games

Colorado Rockies vs. Arizona Diamondbacks Pick  

Senzatela was dismantled in his lone start against the D-Backs this season, registering a 13.50 ERA in 2.0 innings. On the other hand, Kelly dominated the Rockies in his two starts (two wins) against them this year. He posted a microscopic 1.15 ERA over 15.2 innings, and given how good Kelly is playing right now, I am convinced he will have another quality start against Colorado.

The Rockies are way better against southpaws, so this matchup is not going to suit them well, even though they are not bad against righties (.250 BA/4.25 runs per nine innings). I am still giving an advantage to Kelly and D-Backs.

Pick: Take the Diamondbacks -1.5 Run Line at +120

The Total

Senzatela is not going to last long in this one and I am backing the D-Backs to torment him from the opening inning. Betting on Under when the Rockies are involved is equal to suicide because they are scoring a lot of runs but also are allowing a ton of them. They are the second-worst team in the MLB in runs allowed per game (5.49).

Under is 5-2-1 in the last eight H2H meetings in Arizona, Under is 5-2 in the Rockies’ previous seven games vs. a right-handed starter, while Under is 4-1 in the Diamondbacks’ last five home games vs. a right-handed starter.

Pick: Go Over 8 runs at -120
