Rest-of-Season Projections
Sent to minor-league camp
The Astros reassigned Walter to minor-league camp Thursday, Brian McTaggart of MLB.com reports.
ANALYSIS
Walter previously saw big-league action out of the Boston bullpen in 2023, but he was released this past August after a left shoulder strain kept him from pitching throughout the 2024 season. He joined Houston on a minor-league deal shortly after his release from Boston and was cleared for spring training, but he fell short in his bid for a long-relief role with the big club after giving up four earned runs on nine hits and three walks over seven innings across his four Grapefruit League outings. Walter will likely open the season at Triple-A Sugar Land, and he could be a candidate to work out of the 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.
