One key strength for Arizona entering this game is recent pitching form. The Diamondbacks recently held Texas scoreless in a 1-0 victory and also allowed only one run in two separate wins against the Mets. Arizona’s pitching staff has shown it can keep games manageable when the offense does enough to support it.
Texas Tries to Respond at Home
Texas enters the contest with a 19-22 overall record and a 9-10 mark at home. The Rangers have gone 2-3 over their last five games, recently lost to Arizona 1-0 after recently winning over Chicago 3-0 and 6-0. Texas also recently lost to Chicago 7-1 and recently lost to the Yankees 9-2. The Rangers have alternated between strong pitching performances and offensive struggles during this recent stretch.
The Rangers are batting .232 with 149 runs, 311 hits, and 37 home runs. Texas owns a .314 on-base percentage and a .365 slugging percentage. On the pitching side, the Rangers have been solid overall with a 3.59 ERA, a 1.22 WHIP, and a .229 opponent batting average. Texas has also recorded 353 strikeouts while issuing 128 walks.
Texas’ biggest strength entering this game is its overall pitching profile. The Rangers hold the lower ERA, lower WHIP, and lower opponent batting average in this matchup. Even though the offense has struggled at times, Texas has shown the ability to win lower-scoring games behind strong pitching performances.
Arizona Diamondbacks vs Texas Rangers Picks and Prediction
Arizona Diamondbacks vs Texas Rangers Pick
- Pick: Texas Rangers Moneyline
I like Texas in this matchup because the Rangers enter with the stronger overall pitching numbers and have shown they can control games when the pitching staff performs well. Texas owns the lower ERA, lower WHIP, and lower opponent batting average compared to Arizona. While Arizona recently won the first game of the series 1-0, the Rangers also recently shut out Chicago twice during their previous series. In what projects to be another close game, I give the slight edge to Texas at home.
Arizona Diamondbacks vs Texas Rangers Total Pick
- Pick: Under 8.5
I would lean toward the under because both teams have recently played in several lower-scoring games. Arizona recently played games ending 1-0, 2-1, and 3-1, while Texas recently played 3-0, 6-0, and 1-0 games. The Rangers also carry the better overall pitching metrics entering the matchup, including a 3.59 ERA and .229 opponent batting average. With both offenses showing inconsistency and the total sitting at 8.5, the under appears to offer value.
Final Score Prediction: Texas Rangers 4 – Arizona Diamondbacks 3
