The biggest strength for Pittsburgh entering this matchup has been its overall balance. The Pirates own stronger offensive production than San Francisco in nearly every major category while also carrying the lower ERA, lower WHIP, lower opponent batting average, and significantly more strikeouts. Pittsburgh’s recent run of strong pitching performances also stands out after allowing only two combined runs across its last two wins.
Giants Searching for Offensive Consistency
San Francisco enters this matchup with a 14-23 overall record and an 8-11 mark at home this season. The Giants recently lost back-to-back games against San Diego by scores of 5-1 and 10-5 after defeating the Padres 3-2 earlier in the series. Before returning home, San Francisco also dropped two games against Tampa Bay, including a 5-1 loss and a 2-1 extra-inning defeat. The Giants have lost four of their last five games.
The Giants have posted a .238 batting average with 115 runs, 295 hits, and 23 home runs this season. San Francisco also owns a .282 on-base percentage and a .355 slugging percentage. On the pitching side, the Giants carry a 3.96 ERA and a 1.30 WHIP while allowing opponents to hit .236 against them. The pitching staff has recorded 295 strikeouts this year.
One major concern for San Francisco entering this matchup has been offensive production. The Giants have scored only 115 runs this season and have hit just 23 home runs, both noticeably lower than Pittsburgh’s offensive totals. While the pitching numbers remain respectable overall, San Francisco has struggled to generate enough offense consistently during this recent stretch.
Pittsburgh Pirates vs San Francisco Giants Picks and Prediction
Pittsburgh Pirates vs San Francisco Giants Pick
- Pick: Pittsburgh Pirates Moneyline
Pittsburgh enters this matchup playing the better overall baseball and holds advantages offensively and statistically on the mound. The Pirates have won four of their last five games while San Francisco has lost four of five. Pittsburgh also owns stronger team hitting numbers, more power production, and a pitching staff that has limited opposing hitters to a .218 batting average this season. Even though Landen Roupp has pitched well for San Francisco, the overall edge still leans toward Pittsburgh entering Saturday night.
Pittsburgh Pirates vs San Francisco Giants Total Pick
- Pick: Take the under if the total is set at 7.5
I would lean toward the under because both starting pitchers enter with solid ERA and WHIP numbers, and San Francisco’s offense has struggled for much of the season. The Giants have scored only 115 runs through 37 games, while Pittsburgh has recently won games by scores of 1-0 and 4-2. With both pitching staffs carrying respectable numbers overall, this matchup has the potential to stay lower scoring.
Final Score Prediction: Pittsburgh Pirates 4 – San Francisco Giants 2
