One of Arizona’s biggest strengths entering this matchup has been offensive consistency combined with solid starting pitching. The Diamondbacks have scored 25 runs over their last five games while Eduardo Rodriguez enters with one of the stronger ERAs among the pitchers on this slate. Arizona has also played well recently against San Francisco after recently winning over the Giants earlier in the week.

Giants Trying to Keep Recent Offense Rolling

San Francisco enters the contest with a 22-31 overall record and a 12-13 home mark this season. The Giants recently won over the White Sox by scores of 8-5 and 10-3 after previously recently lost to Chicago 9-4. Before that, San Francisco recently lost to Arizona by scores of 6-3 and 5-3. The Giants have won two of their last five games overall entering Tuesday night.

The Giants are batting .247 as a team with 195 runs scored and 449 hits this season. San Francisco has added 46 home runs while posting a .295 on-base percentage and a .387 slugging percentage. The pitching staff enters with a 4.22 ERA and 1.34 WHIP while allowing opponents to hit .243 against them. Giants pitchers have also generated 419 strikeouts this season.

One challenge for San Francisco entering this matchup has been pitching inconsistency. The Giants carry the higher ERA and WHIP compared to Arizona, and Tyler Mahle has struggled this season with a 6.10 ERA. While San Francisco’s offense showed improvement during the recent series against Chicago, the pitching staff continues allowing opponents to generate scoring opportunities regularly.

Arizona Diamondbacks vs San Francisco Giants Picks and Prediction

Arizona Diamondbacks vs San Francisco Giants Pick

  • Pick: Arizona Diamondbacks Moneyline

Arizona enters this matchup with stronger recent form and a clear advantage on the mound with Eduardo Rodriguez starting. Rodriguez has posted a 2.24 ERA and allowed only four home runs across 60.1 innings this season. The Diamondbacks have also won four of their last five games and recently defeated San Francisco earlier in the week. With Tyler Mahle carrying a 6.10 ERA for the Giants, Arizona holds the stronger overall position entering this game.

Arizona Diamondbacks vs San Francisco Giants Total Pick

  • Pick: Over 8

I like the over in this matchup because both teams have recently been involved in higher-scoring games. Arizona recently scored 9, 5, 2, and 6 runs over the last several games, while San Francisco recently put up 8 and 10 runs against Chicago. Tyler Mahle’s elevated ERA also increases the likelihood of scoring opportunities for Arizona throughout the game.

Final Score Prediction: Arizona Diamondbacks 6 – San Francisco Giants 4
