Rest-of-Season Projections
Signed a one-year contract with the Astros in May of 2025.
Tough-luck loss in quality start
Walter (1-2) took the loss Wednesday against the Guardians, giving up two runs on two hits and no walks in six innings. He struck out seven.
Analysis
Walter continues to provide length for the Astros, having now thrown at least five innings in each of his first seven starts in 2025. The 28-year-old southpaw also tallied 16 whiffs Wednesday, and he's now posted four quality starts for the year. Walter has logged a 3.98 ERA, 1.01 WHIP and a pristine 40:2 K:BB through his first 40.2 frames prior to the All-Star break, and he should continue to hold down a major-league roster spot to help eat innings for Houston's injury-riddled rotation.

Past Fantasy Outlooks
2024
2023
Walter has a spot on the 40-man roster and will compete as a backend starter during spring training. Beyond Lucas Giolito and Brayan Bello, Walter's name can be thrown into the mix with Tanner Houck, Garrett Whitlock and Nick Pivetta. The 27-year-old lefty had a rocky first half, which included a 6.26 ERA over 23 innings mid-summer for Boston. He wasn't much better before that at Triple-A Worcester; however, the right-hander thrived during the second half upon his return to Triple-A (1.48 ERA over 30 innings). He attributed his success to pounding the strike zone. That's what he did during a breakout 2021 campaign to put himself on the prospect radar. The organization will probably want Walter to build off the second-half success and begin 2024 at Worcester. If he's to break camp with Boston, it will be likely be as a multi-inning relief arm.
