San Francisco Searches for Consistency

The Giants enter this contest with a 34-48 overall record and a 17-26 road record. San Francisco recently defeated Atlanta, previously lost to Atlanta, and before that won two of three games against the Athletics after dropping the opener of that series. The Giants have posted a 3-2 record over their last five games despite their overall struggles this season.

San Francisco is batting .255 with 334 runs, 717 hits, 88 home runs, a .308 on-base percentage, and a .418 slugging percentage. The pitching staff owns a 4.35 ERA, a 1.37 WHIP, 311 walks, 644 strikeouts, and a .248 opponent batting average. The Giants are 15-17 in day games.

The Giants’ biggest strength is their ability to put the ball in play. They lead Arizona in batting average, hits, and slugging percentage. Those offensive advantages have helped keep them competitive even though they have struggled to turn those opportunities into wins consistently.

Arizona Looks to Protect Home Field

The Diamondbacks come into Monday’s game with a 41-41 overall record and a strong 24-17 home record. Arizona recently lost back-to-back games to Tampa Bay after previously winning two straight over St. Louis before dropping another close game in that series. The Diamondbacks have gone 2-3 over their last five contests but return home where they have played above .500 this season.

Arizona is batting .239 with 349 runs, 650 hits, 73 home runs, a .308 on-base percentage, and a .386 slugging percentage. The Diamondbacks have produced a 4.32 ERA, a 1.30 WHIP, 246 walks, 563 strikeouts, and a .251 opponent batting average. They are also 17-16 in day games.

Arizona’s biggest strength in this matchup is its pitching efficiency. The Diamondbacks own the lower team ERA and WHIP while issuing considerably fewer walks than San Francisco. Combined with the stronger numbers from the projected starting pitcher, those statistics provide a solid foundation entering this game.

San Francisco Giants vs Arizona Diamondbacks Picks and Prediction

San Francisco Giants vs Arizona Diamondbacks Pick

• Pick: Arizona Diamondbacks Moneyline

Arizona is my selection for this matchup. The Diamondbacks own the better overall record, the stronger home record, and have a clear edge in the projected starting-pitching matchup. Eduardo Rodriguez has posted outstanding numbers this season, and Arizona also has the lower team ERA and WHIP. While San Francisco has been slightly better offensively in several categories, the Diamondbacks’ advantage on the mound makes them my preferred side.

San Francisco Giants vs Arizona Diamondbacks Total Pick

• Pick: Under 8.5

I would take the under if the total is set at 8.5. Arizona’s projected starter enters with a 2.27 ERA, and the Diamondbacks have the better overall team ERA and WHIP in this matchup. Neither offense has reached 350 runs this season, and I expect the stronger pitching numbers to keep scoring in check.
