The Pittsburgh Pirates head into today's series finale against the San Francisco Giants as a heavy 60% moneyline favorite, with first pitch at PNC Park scheduled for 12:35 p.m. ET.
It will be a bullpen game for Pittsburgh, which has been shutting the door late in games lately. That has me backing the hosts in my Giants vs Pirates predictions. Find out more in my MLB picks for Thursday, Sep. 3.
Who will win Giants vs Pirates today: Pirates moneyline (60%)
For help understanding probabilities, see our odds calculator.
The Pittsburgh Pirates will send reliever Lake Bachar to the mound today, and while he doesn't typically work more than two innings, the righty has allowed just two earned runs across his last three outings.
The Bucs’ bullpen also owns a 3.27 FIP over the last week with no home run damage, and the San Francisco Giants have just a .148 ISO over their last seven games.
The visitors counter with Blade Tidwell, who owns a 5.81 FIP over his previous two starts while surrendering 2.53 HR/9.
Pittsburgh has the offensive profile to capitalize, carrying a 111 wRC+ over the last week. The Bucs have the edge.
Play this pick up to 62%.
COVERS INTEL: PNC Park is where the Pirates thrive offensively with a 112 wRC+. On the road, they're much worse, posting a 91 wRC+. 
Giants vs Pirates Over/Under pick: Under 8.5 (46%)
I’m leaning Under 8.5, even with San Francisco producing a 110 wRC+ over the last week.
The issue is power. Both lineups have been light in the ISO department, which makes it harder to trust either side to break this open with one big swing.
The bullpen profiles also support a lower-scoring game, with the Giants’ relief corps posting a 3.00 FIP over its previous 31 innings while allowing just 0.58 HR/9.
Pittsburgh’s bullpen is also in strong form, giving this game fewer late-inning scoring paths. With limited power and two steady relief groups, the Under is the play.
Play up to 50%.
Giants vs Pirates home run prediction: Rafael Devers (14%)
Rafael Devers is worth a look given his recent power output. The slugger has clubbed three homers over his last seven games while posting a .370 ISO during that span.
Devers also owns a 52.7% hard-hit rate and 14.3% barrel rate recently. He has put just 38.1% of his contact in the air over the last week, but 37.5% of those fly balls have left the yard.
The matchup against Pittsburgh’s bullpen is not perfect given its ability to limit homers, but Devers’ current form is hard to ignore.
I'd play this pick up to 25%
- ML/RL bets: 64-74, -18.86 units
- Over/Under bets: 75-59, +4.39 units
Giants vs Pirates weather
Weather at PNC Park looks warm but slightly unsettled, with partly cloudy skies and temperatures climbing from 83°F to 89°F. Rain chances sit between 16-33%, so there’s some shower risk, but nothing that screams major postponement concern. Winds are moderate around 8-11 mph, and the warm air could slightly help carry.
