The San Francisco Giants (58-82) conclude their series against the Pittsburgh Pirates (68-72) at PNC Park today, with first pitch scheduled for 12:35 PM ET. I am looking closely at the props market after the Giants secured a tight 5-4 victory yesterday, fueled by a booming home run from Rafael Devers.

Despite dropping that contest, the Pirates open as -153 moneyline favorites at home in the MLB odds, alongside an 8.5-run game total. As these National League squads battle this afternoon, I’m finding more value in the props market rather than on the moneyline or total. Keep reading for my favorite Pirates vs Giants props and best bets for Sep 3, below.

Pirates vs Giants Best Bets

Finding the right value in the Pirates vs Giants props requires digging into recent statistical form and historical matchups. Below are my three favorite MLB player props for today’s afternoon clash in Pittsburgh.

Bryan Reynolds Over 1.5 Total Bases (+127 at Kalshi)

MarketOvUn
Reynolds 1.5 Total Bases+127-138

Bryan Reynolds enters today with a clear head to head history advantage over Giants starter Blade Tidwell. In a small career sample, Reynolds is batting .500 against Tidwell per the MLB batter vs pitcher stats, with a three-run home run. The Pirates outfielder has maintained a steady .262 average with 1.1 hits per game over his last 10 contests. Meanwhile, Tidwell carries a vulnerable 4.54 ERA and 1.22 WHIP across 37.2 innings this season. At +127, Kalshi offers the best available odds. Grab the Kalshi promo code now to tail this bet.

The total-bases angle is supported by the shape of Reynolds’ recent success. His 1.1 hits per game over the last 10 contests also gives him a realistic path through multiple singles or an extra-base hit. Tidwell’s 1.22 WHIP indicates that baserunners have been a recurring issue, and a 4.54 ERA further raises the chance that Reynolds sees hittable pitches in run-producing situations.

Rafael Devers Over 1.5 Total Bases (+156 at Kalshi)

MarketOvUn
Devers 1.5 Total Bases+156-163

Without established betting trends to lean on, I look strictly at recent production. Devers possesses no history against Pirates starter Jared Jones, forcing me to weigh his current form against the pitcher’s overall profile. Devers has looked like an MLB MVP odds candidate over his last 10 games, batting .421 with a massive 1.453 OPS while averaging 1.6 hits and 0.6 home runs per game. Jones has struggled with a 4.83 ERA and 1.28 WHIP this season, yielding plenty of traffic.

A .421 average paired with 1.6 hits per game over his last 10 means he has frequently exceeded the one-hit baseline needed to threaten 1.5 total bases, while 0.6 home runs per game highlights genuine power rather than a singles-only profile. His 1.453 OPS captures the combined on-base and slugging impact.

Blade Tidwell Under 4.5 Strikeouts (-166 at Caesars Sportsbook)

MarketOvUn
Tidwell 4.5 Strikeouts+130-166

Tidwell’s season strikeout average signals a distinct edge on the under. The starting pitcher averages just 7.41 strikeouts per nine innings and typically pitches only 5.13 innings per start, leaving him a narrow window to record five punchouts before his efficiency falls off a cliff. Given Tidwell’s 4.54 ERA and pedestrian strikeout rate, the under is mathematically sound.

The workload math is the key reason to prefer the under. At 7.41 strikeouts per nine innings, Tidwell’s rate translates to roughly 4.2 strikeouts across his 5.13-inning average start. That estimate sits below the 4.5 line before accounting for the possibility of an early hook. He therefore needs either extra length or a better-than-season strikeout performance to reach five. His 4.54 ERA also suggests contact can extend innings without necessarily creating strikeout opportunities. Start betting with the Caesars Sportsbook promo code now to grab the best odds at -166.
