Signed a one-year contract with the Astros in May of 2025.
Gives up five runs in no-decision
PHouston Astros
July 3, 2025
Walter did not factor into Thursday's decision against the Rockies, allowing five runs on eight hits while striking out three across five innings. He did not issue a walk.
Analysis
Walter entered Thursday's game with three quality starts over his last four outings, but he wasn't able to replicate that success in Colorado. He generated 13 whiffs on 91 pitches (62 strikes) but gave up at least one run in three of the five innings he pitched and avoided the loss only thanks to strong run support. Walter is now at a 4.15 ERA, 1.13 WHIP and 33:2 K:BB over 34.2 innings this season, and he's lined up to face the Guardians at home next week.

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.
Walter began 2022 at Double-A Portland and was promoted to Triple-A Worcester after he posted a 2.88 ERA with 68 strikeouts across 50 innings, but he made only two starts for Worcester before he was lost for the season with a neck strain. The left-hander was added to the Red Sox's 40-man roster in November to protect him from being selected during the Rule 5 draft, which clearly indicates how he's valued by the organization. Boston's rotation has more question marks than locks, which should provide Walter the chance to make his big-league debut in 2023. However, he's likely to open the campaign at Triple-A and may need to pitch well there to receive that opportunity.
