June 25, 2025 9:47 PM : Flaherty (5-9) took the loss Wednesday against the A's, allowing three runs on five hits and four walks over six innings. He struck out seven.
Analysis: One pitch proved to be enough to stick Flaherty with the loss Wednesday -- he gave up a three-run homer to Nick Kurtz with two outs in the third inning that proved to be the difference in a 3-0 defeat. While it's the third straight loss for Flaherty, it's a step in the right direction for the right-hander after he'd given up 15 runs in just five innings over his previous two outings. Overall, Flaherty sports a 4.80 ERA with a 1.23 WHIP and 100:35 K:BB across 16 starts (84.1 innings) this season. He's currently lined up to face the Nationals on the road his next time out.
