The biggest challenge for Arizona has been offensive consistency. The Diamondbacks have scored fewer runs and hit fewer home runs than St. Louis. While their pitching staff owns a slightly higher ERA than the Cardinals, Arizona has done a better job limiting opposing hitters, as shown by its lower opponent batting average.

Cardinals Looking to Build Momentum

The Cardinals come into this game with a 42-34 overall record and a 22-17 home record. St. Louis has gone 2-3 over its last five games. The Cardinals recently defeated Arizona and Kansas City while suffering losses to Kansas City twice and San Diego.

St. Louis is hitting .249 as a team with 352 runs scored, 639 hits, and 87 home runs. The Cardinals have produced a .328 on-base percentage and a .400 slugging percentage. On the mound, they own a 4.26 ERA and a 1.34 WHIP while recording 577 strikeouts. Opponents are batting .256 against St. Louis. The Cardinals are 28-16 in night games.

The strength of St. Louis is its balanced offensive production. The Cardinals hold advantages in batting average, runs scored, hits, home runs, on-base percentage, and slugging percentage. Those offensive edges have helped them maintain a winning record and a strong mark in night games throughout the season.

Arizona Diamondbacks vs St. Louis Cardinals Picks and Prediction

Arizona Diamondbacks vs St. Louis Cardinals Pick

  • Pick: St. Louis Cardinals Moneyline

The Cardinals enter this matchup with the better overall record, the stronger home record, and advantages across most offensive categories. St. Louis also owns a slight edge in the matchup predictor and already picked up a 3-2 victory over Arizona earlier in the series. With the Diamondbacks still listing their starter as undecided, the Cardinals are the preferred side.

Arizona Diamondbacks vs St. Louis Cardinals Total Pick

  • Take the over if the total is set at 8.5.

I would lean toward the over if the number is set at 8.5. St. Louis has scored 352 runs and hit 87 home runs this season, while Arizona's pitching staff owns a 4.29 ERA. The Cardinals' projected starter also enters with a 5.23 ERA and has allowed 15 home runs. Those numbers suggest scoring opportunities for both teams.

Final Score Prediction: St. Louis Cardinals 6 – Arizona Diamondbacks 4
