Arizona Diamondbacks

As the Arizona Diamondbacks prepare to face the Colorado Rockies on August 9, 2025, the stakes are heightened following the D-Backs’ decisive 6-1 victory over the Rockies in their previous matchup. The Diamondbacks, currently sitting at 55-61, are looking to capitalizing on their strong offense, which ranks 4th in MLB. Meanwhile, the Rockies, struggling with a dismal record of 30-85, have seen their offense falter, ranking 25th overall.

On the mound, Arizona will feature Eduardo Rodriguez, who has had a rough season with a 4-7 record and an ERA of 5.53. However, his xFIP of 4.19 suggests he has been somewhat unlucky, and he is projected to strike out an impressive 6.0 batters against a Rockies lineup that has struggled this season. Rodriguez’s recent form includes a solid outing in his last start where he allowed just 2 earned runs in 5 innings.

The Rockies will counter with Bradley Blalock, whose 1-3 record and a troubling 7.68 ERA underscore his struggles on the mound. In his last appearance, Blalock was hit hard, giving up 7 earned runs over 6 innings. Projections indicate he’ll pitch fewer innings and continue to struggle against a high-powered Arizona offense.

While the Diamondbacks’ bullpen ranks 25th in MLB, the overall offensive capabilities give Arizona a significant edge. They are favored with a moneyline of -225, which reflects a strong confidence in their ability to overwhelm the Rockies. Given the disparity in performance and the recent history between these two teams, the Diamondbacks are poised to secure another victory.

Colorado Rockies Insights

• Bradley Blalock – Over/Under 2.5 Strikeouts (-145/+115)
  Bradley Blalock’s 2101-rpm fastball spin rate this year grades out in the 11th percentile among all SPs.
  Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs.
• Hunter Goodman – Over/Under 1.5 Total Bases (+110/-140)
  As it relates to his wOBA and overall offense, Hunter Goodman has been lucky this year. His .366 figure has been a fair amount higher than the leading projection system (THE BAT X)’s version of Statcast-based Expected wOBA (xwOBA) at .291.
  Explain: xwOBA uses highly advanced Statcast data to measure a player’s overall hitting ability more accurately than actual wOBA can.
• Colorado Rockies – 2H Moneyline
  The Colorado Rockies bullpen projects as the 10th-worst in MLB, per the leading projection system (THE BAT).
  Explain: Most bettors only consider the starting pitcher, but a weak bullpen sneakily creates an easier matchup for the opposing offense and boosts a game’s runs.

Arizona Diamondbacks Insights

• Eduardo Rodriguez – Over/Under 17.5 Pitching Outs (-130/+100)
  Eduardo Rodriguez has averaged 91.5 adjusted pitches per start this year, ranking in the 75th percentile.
  Explain: Pitchers who average more pitches per game are more likely to go deeper into games and record more outs.
• Tyler Locklear – Over/Under 0.5 Hits (-185/+140)
  Tyler Locklear is penciled in 6th on the lineup card today, which would be a downgrade from his 71% rate of hitting in the top-half of the batting order this season.
  Explain: The lower in the order a player bats, the fewer plate appearances he will get and the fewer opportunities he will get to hit the Over for every market. A player who hits lower in the order than he normally does may provide extra value opportunity since the market may be based on him hitting higher.
• Ketel Marte – Over/Under 1.5 Total Bases (-110/-120)
  In today’s game, Ketel Marte is at a disadvantage facing the league’s 3rd-deepest RF fences given that he hits his flyballs to the pull field at a 35.7% rate (91st percentile).
  Explain: This player’s skill set does not match up particularly well with the park he’s in today, which may lead to worse-than-usual performance.
