Pirates and Giants Face Off in High-Scoring Series Finale at PNC Park

Thirty-four runs across 19 innings. That is the baseline we are working with as the San Francisco Giants and Pittsburgh Pirates walk into PNC Park for Thursday afternoon's rubber match. The series has been loud, chaotic, and entirely unpredictable. Pittsburgh took Tuesday's opener 13-12 on a ninth-inning throwing error, and San Francisco punched back Wednesday with a 5-4 victory in 10 innings. Now, with the series on the line at 12:35 p.m. ET on September 3, 2026, the Pirates are throwing a tactical curveball.[2][4]

Rather than handing the ball to a traditional starter, Pittsburgh manager Derek Shelton is opting for a pure bullpen game. The Pirates moved Jared Jones' turn in the rotation to Friday against the Angels, leaving Thursday's innings to the relief corps. Right-hander Lake Bachar is expected to serve as the primary bulk option. Bachar has been highly effective in this exact role, allowing just two earned runs across his last three outings.[2][3]

The strategy makes sense when you look at the underlying metrics. The Pirates' bullpen owns a sharp 3.27 FIP over the last week and has completely suppressed home run damage. By turning the game over to the relievers from the first pitch, Pittsburgh is betting that a parade of fresh arms can neutralize a San Francisco lineup that has struggled to generate consistent power. The Giants have posted a meager .148 ISO over their last seven games, relying heavily on stringing together singles rather than clearing the fence.[3]

San Francisco, meanwhile, is taking a more traditional route, handing the ball to 25-year-old right-hander Blade Tidwell. As noted by The Spread, Tidwell "carries a 4.54 ERA and a 1.22 WHIP through 37.2 innings, with 31 strikeouts against 13 walks in five starts." The rookie's recent form has been a mixed bag. In his last outing, the Arizona Diamondbacks tagged him for six earned runs over five innings. But the start prior to that showcased his ceiling: 5.2 scoreless innings at Fenway Park with seven strikeouts.[2]

Tidwell's primary challenge will be navigating a Pittsburgh lineup that transforms into an offensive juggernaut at home. According to Covers, "PNC Park is where the Pirates thrive offensively with a 112 wRC+." The attack is anchored by Nick Gonzales, who leads the club with 152 hits and a .310 batting average, providing a relentless contact presence at the top of the order. Behind him, Brandon Lowe supplies the heavy artillery, entering Thursday with 29 home runs and 83 RBI.[3][5]

The Giants counter with their own heavy hitters, most notably Rafael Devers. The slugger has been the engine of San Francisco's offense, launching 32 home runs and driving in 82 runs this season. Devers was instrumental in Wednesday's extra-inning victory, reaching base in four of his five plate appearances, including a crucial home run. He is currently riding a 10-game streak of getting on base at least twice. Setting the table for Devers is Luis Arraez, who continues to be one of the National League's most consistent bats with a .324 average and 136 hits.[4][5]

Neither team is chasing a division title this late in the calendar. Pittsburgh sits at 68-72, while San Francisco enters at 58-82. But as Fubo's analysts point out, "San Francisco comes in at 58-82, a team that has shed playoff ambitions but not competitive edge — the Giants have gone 6-4 over their last ten games, showing they can still make life difficult for opponents." These are two clubs playing for pride, roster spots, and individual milestones, a dynamic that often produces sharper, more aggressive baseball than a high-stress pennant race.[5]

The deciding factor on Thursday will likely come down to roster availability and fatigue. This is a getaway day game following an extra-inning night game, meaning both pitching staffs are stretched thin. If Tidwell struggles with his command early—his walk rate has been the dividing line between his good and bad starts—the Giants will be forced to expose a middle relief group that already worked heavily on Tuesday and Wednesday. Pittsburgh's bullpen day is a calculated risk, but it is one they are equipped to handle in their home park.[2][6]

The math in this finale leans toward the home dugout. The Pirates project as the more efficient run-prevention unit in this specific setup, backed by an offense that hits significantly better in its own building. While the Giants have shown serious resilience over the last 48 hours, asking a rookie starter with command issues to quiet a locked-in top of the order is a tall order. If Pittsburgh's parade of relievers can navigate Devers and Arraez without surrendering the long ball, the Pirates are positioned to secure the series victory before both clubs pack up and head out of town.[3][6]
