The Pittsburgh Pirates are riding high after a gritty 1-0 shutout win over the Arizona Diamondbacks on Wednesday night, leveling the season series. That victory wasn't just any win—it marked the Pirates' second shutout in their last five games and their fourth win in that stretch. For Arizona, the loss was their third shutout of the season and their second in the past week, signaling a rough patch. The Diamondbacks have dropped five of their last six contests, and it's their worst stretch of the year. During this six-game slide, Arizona's pitching ranks 24th in MLB with a 5.22 team ERA, while their offense has cratered to last in the league with a .201 batting average. Zac Gallen takes the mound for the Diamondbacks on Thursday, hoping to reverse a trend—after Arizona won three of four with Gallen starting earlier, they've lost his last two outings.
On the flip side, the Pirates are finding their groove. They've won four of their last five, and Wednesday's shutout was fueled by a dominant 8.0-inning performance from Paul Skenes. Pittsburgh's pitching has been a mixed bag recently—they've also allowed nine and seven earned runs in separate games during this five-game span—but they'll hand the ball to Mitch Keller, who has the Pirates on a three-game winning streak when he starts. Keller's 2026 stats are solid: 41.0 innings pitched, a 3-1 record, 2.85 ERA, 1.05 WHIP, 31 strikeouts, and 12 walks. Gallen counters with 32.1 innings this season, though his exact numbers are still developing.
Thursday's game (May 6) features a compelling pitching duel: Keller vs. Gallen. The moneyline has the Diamondbacks at -108 and the Pirates at -112, making it a near pick'em. The spread is Diamondbacks +1.5 (-175) and Pirates -1.5 (+144). For fans looking to catch the action, check your local listings or MLB's schedule for first pitch details.
