Arizona Diamondbacks

The Arizona Diamondbacks lost the rubber game of their series against the Padres and are currently fourth in the NL West standings, 12 games behind the Dodgers for the top spot. They are also nine games behind the Mets for the final wild card spot in the National League playoff race. In their recent game against San Diego, the Diamondbacks struggled to produce offensively, finishing with only four hits and going 0-4 with runners in scoring position. Despite a strong performance from pitcher Anthony DeSclafani, the team ultimately fell short with Kyle Backhus taking the loss. Zac Gallen will be starting in the upcoming game for his 24th start of the season, with a record of 8-12 and a 5.48 ERA. In his last start against the Athletics, he earned the win after throwing six innings and allowing two runs. Over his career, Gallen has had success against the Rockies with an 8-1 record and a 3.53 ERA in 18 starts.

Colorado Rockies Achieve Fastest -300 Run Differential in MLB History, but Arizona Diamondbacks Have the Edge

The Colorado Rockies have made history by achieving the fastest -300 run differential in MLB history, doing so in just 114 games. This surpasses the previous record set by the 1911 Boston Rustlers, who achieved the same differential in 118 games. Despite their impressive performance at home, the Rockies have struggled on the road with a 14-42 record and have a run line record of 58-104. The Arizona Diamondbacks, despite recent setbacks due to trading players like Josh Naylor and Eugenio Suarez, are positioned better than the Rockies. While Gallen has had a challenging season overall, he has consistently performed well against Colorado. With Gomber still seeking his first win of the season, the odds favor Arizona in this upcoming game. It is advisable to place your bet on the Diamondbacks as they face the Rockies at home in the opening game.
