The Astros announced Friday that theyve claimed infielder off waivers from the As and designated right-hander for a signment in a corresponding move. Houston also placed lefty on the 15-day injured list due to elbow inflammation and recalled righty from Triple-A Sugar Land. Davidson, 27, was the Athletics first-round pick back in 2017. He was designated for a signment earlier in the week. The Clemson product made his big league debut this season and collected his first few big league hits but only tallied 24 plate appearances. Hes spent the bulk of the season in Triple-A Las Vegas, hitting .263/.412/.397 with a Gabriel Landeskog Jersey colo sal 19.4% walk rate but a 26.4% strikeout rate and only seven homers in 330 plate appearances. Thats Davidsons third run at the Triple-A level. Hes a career .278/.374/.446 hitter in just over 900 plate appearances there. Davidson has primarily been a shortstop in his pro career but has at least 500 innings at all four infield positions and another 350 innings of outfield work under his belt. Hell add a switch-hitting depth piece with a full slate of minor league options to the Houston depth chart. The Astros added Robertson, 27, in an April 1 trade with the Blue Jays. Hes spent the whole season in Triple-A, where hes worked 32 2/3 innings of relief with a 4.68 ERA, 24.8% strikeout rate and grisly 17.2% walk rate. Robertson has a history of mi sing bats in the upper minors but also well below-average command. Hes pitched 35 2/3 innings acro s four teams (Dodgers, Red Sox, Cardinals, Jays) and posted a 5.30 ERA while fanning nearly a quarter of his opponents against a 6.8% walk rate. Houston has five days to trade him or place him on outright waivers. Walters IL placement is the latest in a seemingly neverending spree of injuries to Astros pitchers. The former Red Sox prospect signed a minor league deal over the winter and has been a revelation in Houston filling in for other injured starters like and . In 53 2/3 innings, Walter has posted a 3.35 ERA with a 24.5% strikeout rate and an outrageous 1.9% walk rate (four walks). Hes started nine games and looked to have a rotation spot locked down before his elbow flared up. Elbow concerns for any pitcher are ominous, but thats perhaps particularly true in Walters case. He mi sed the entire 2024 season due to injury albeit a rotator cuff strain rather than anything pertaining to his elbow. Still, its a discouraging development for him to run into another arm injury in relatively short order after returning from an entirely lost season. The Astros were on the lookout for pitching earlier this summer, but general manager Dana Brown recently suggested that in light of a serious injury to third baseman (to say nothing of an increasingly protracted absence for ), his focus is instead on bolstering the lineup. That, of course, was before word came down about Walters elbow. With Walter on the shelf, Houstons rotation includes co-aces and and rookies and . Candidates to step into Walters spot include , and , although Houston also has , and on the mend. Andrew Cogliano Jersey
