Rest-of-Season Projections
Signed a one-year contract with the Astros in May of 2025.
Nearing mound work
Walter (elbow) resumed playing catch Tuesday, and Astros manager Joe Espada relayed Sunday that the right-hander could throw off a mound in "the next few days," Matt Kawahara of the Houston Chronicle reports.
Analysis
Walter shouldn't be in line for an extended stay on the injured list after he was able to start throwing again five days after being shelved with elbow inflammation, but he still appears likely to be out for longer than the minimum 15 days. Assuming Walter is able to advance to throwing bullpen sessions by the end of the week, he could then move on to facing hitters the week after that. Through nine starts with Houston this season, Walter owns a 3.35 ERA, 0.93 WHIP and 52:4 K:BB in 53.2 innings, but in spite of his impressive numbers, he may be on the outside looking in for a rotation spot upon his return. Spencer Arrighetti (thumb), Cristian Javier (elbow) and Luis Garcia (elbow) are all in the midst of rehab assignments and could beat Walter back from the IL, though Javier and Garcia won't necessarily be guaranteed rotation spots either.

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.
