Jack Flaherty: Breaking News

Flaherty allowed three runs on six hits across five innings and did not factor into the decision in Sunday's 5-4 win over the Mariners. He walked one and struck out seven. Flaherty earned his first win of the season his last time out but was unable to fully carry that momentum into his next start. The righty has now allowed three earned runs or more in five of his last six appearances, and he's sitting with an underwhelming 5.31 ERA overall. Flaherty at least had the strikeout stuff working Sunday, which pushed him up to 77 this year across 62.2 innings. That's the upside that makes Flaherty intriguing for fantasy managers, though he's yet to put everything together this year. He's penciled in to face the Guardians on the road Saturday the next time he takes the mound.

Flaherty (1-7) picked up the win Tuesday, allowing five hits and two walks over five scoreless innings in an 8-0 rout of the Rays. He struck out six. The veteran right-hander got lifted after 94 pitches (56 strikes), falling short of his second quality start of 2026, but he finally collected his first win after getting stuck with the loss in his five prior trips to the mound. Flaherty has a 4.71 ERA and 1.40 WHIP in 28.2 innings since the beginning of May, but his 38:7 K:BB over that stretch offers some hope he'll be able to turn a tough season around. He'll look to build on this effort in his next outing, which is scheduled to come at home this weekend against the Mariners.

Flaherty (0-7) took the loss against the Angels on Thursday, completing 5.2 innings and allowing three runs on six hits and one walk while striking nine batters. Flaherty was dominant at times, racking up 20 whiffs and nine punchouts. He held the Angels scoreless through four frames, but he lost steam in a three-run fifth inning, and the lack of run support from Detroit's offense saddled Flaherty with yet another defeat. The veteran right-hander is not only tied for the MLB lead with seven losses, he's also yet to win a game through 12 starts. Flaherty is at least providing his fantasy managers with punchouts -- he has 64 over 52.2 frames -- but his 5.81 ERA and 1.61 WHIP have landed him on many waiver wires.
