Latest On Astros’ Rotation Plans

The Astros lost Spencer Arrighetti to the injured list this week, as the righty suffered a broken thumb on a fluke injury when he was struck by a ball during batting practice. Manager Joe Espada said this afternoon that Arrighetti will avoid surgery but will remain in a cast for at least two weeks (relayed by Chandler Rome of The Athletic). He’ll be sent for imaging at that point.

Arrighetti is clearly going to be shelved beyond the 15-day minimum. The Astros need to add someone to the rotation behind Framber Valdez, Hunter Brown, Hayden Wesneski and Ronel Blanco. It seems that rookie right-hander Ryan Gusto is going to get the first opportunity. The Astros list Gusto as the probable starter for their game against the Angels on Saturday.

Assuming plans don’t change within the next two days, Gusto will be making his first big league start. He was lined up to start the final game of the regular season in 2024. Houston had already clinched a playoff spot and called up Gusto to rest their playoff starters. That game was canceled because of rain, which delayed the 26-year-old’s big league debut by six months.

Gusto pitched well enough in Spring Training to break camp, albeit in a relief role. He has tossed eight innings over four appearances, allowing only one run with nine strikeouts and two walks. Gusto worked 2-3 innings in each of his first three outings. He tossed one inning and 15 pitches in yesterday’s extra-inning win in Seattle. He’ll get three days rest before his first start. Gusto started 26 of 29 appearances in Triple-A last season. He worked to a solid 3.70 earned run average with a 22.6% strikeout rate through 148 1/3 innings in the Pacific Coast League.

Houston has off days in each of the next three Thursdays. That allows them to operate without a fifth starter following Gusto’s appearance on Saturday until their series against the Blue Jays between April 21-23. Lance McCullers Jr. figures to return before Arrighetti does. He has made a pair of minor league rehab starts, tossing 50 pitches in an outing for Double-A Corpus Christi on Saturday. McCullers has not pitched in an MLB game since the 2022 World Series because of multiple arm injuries, so the Astros will surely proceed with caution as they build the righty back.
