A spate of unrelenting injuries to the rotation resulted in 14 different pitchers making starts for the Houston Astros this season, with Ronel Blanco joining that group on Monday when he made his season debut after undergoing Tommy John surgery.

Hayden Wesneski, slated to make a rehab start for Triple-A Sugar Land on Thursday, should be next to return for Houston.

The Astros claimed their three-game interleague series against the Miami Marlins with a 5-3 victory on Tuesday behind Tatsuya Imai.

Five Astros have made at least 10 starts, a collection that doesn't include ace Hunter Brown, who returned from an extended stint on the injured list in mid-June.

"Some of those guys that we're getting back have pitched out of the bullpen, so as we continue to map out the next couple of weeks and consider adding some pitching at the deadline, with all those pieces, would they fit," Astros manager Joe Espada said.

"We're going to move some things around so we can make this work."

Right-hander Peter Lambert (8-5, 3.03 ERA) is scheduled to start on Wednesday as the Astros pursue the series sweep.

Lambert is 2-0 with a 1.02 ERA in three starts this month and has allowed one run or fewer in each start, including on June 17 against the Baltimore Orioles. He worked six innings in that game and surrendered one run on three hits and three walks with a season-high 10 strikeouts over six innings.

Lambert is 1-0 with a 6.35 ERA in four career appearances (three starts) against the Marlins. In his previous start against Miami on May 2, 2024, he allowed four runs on five hits and three walks with three strikeouts over 3 1/3 innings and did not factor into a 5-4 loss with the Colorado Rockies.

Right-hander Sandy Alcantara (10-5, 3.89) has the starting assignment for Miami.

Alcantara has produced a quality start in all three starts this month, going 1-1 with a 2.14 ERA. He went 7-0 with a 2.98 ERA during a seven-start stretch before a 3-2 loss to the Cleveland Guardians on July 10.

He did not factor into the decision of a 2-1 loss to the Milwaukee Brewers last Friday after allowing one run on three hits and four walks with seven strikeouts over six innings.

Alcantara has faced the Astros once previously. He surrendered six runs on nine hits and one walk with five strikeouts over seven innings in an 8-2 home loss on Aug. 4, 2025.

All-Star shortstop Otto Lopez returned from a two-game injury hiatus (finger) for the Marlins, which allowed Miami manager Clayton McCullough to tinker with his lineup.

Lopez batted leadoff for the ninth time this season and finished 0-for-3 with two walks. McCullough is aiming to build protection around left-handed hitting Kyle Stowers with the right-handed hitting Lopez and Heriberto Hernandez, plus switch-hitting Xavier Edwards.

"Just trying to have Stowers be shielded as best I can from left(-handed pitching), and if they are going to throw left on Stowers, then at least you have Otto and (Hernandez) around him, X (Edwards) behind him," McCullough said.

"Before Otto got hurt, I was thinking about potentially going this route with hitting him (leadoff), hitting Bert (third). If people still want to bring in left on Stowers to try to mitigate some of his slug, at least they're going to have to go through Bert and X before they get to (lefty Liam) Hicks."
