The Diamondbacks announced Friday that they’ve claimed righty Rogelio Armenteros off waivers from the Astros and outrighted infielder Domingo Leyba to Triple-A Reno. The D-backs’ roster is at 37 players. The Astros are down to 35.
Armenteros, 26, didn’t pitch in 2020 owing to surgery that removed a bone spur from his right elbow. He made his big league debut with the Astros in 2019, however, and pitched to a 4.00 ERA with an 18-to-5 K/BB ratio in 18 innings (four starts). The righty has a generally sharp track record in parts of three seasons in the hitter-friendly Triple-A Pacific Coast League, having compiled a 3.73 ERA with averages of 10 strikeouts, 3.4 walks and 1.2 homers per nine innings pitched. He also has a minor league option remaining, so he’ll represent a nice depth addition for the D-backs’ staff.
Leyba, 25, came to the D-backs alongside Robbie Ray back in 2014’s three-team swap that sent Didi Gregorius to the Bronx and Shane Greene to Detroit. He made his MLB debut in 2019 and batted .280/.367/.440 in a tiny sample of 30 plate appearances, but he’s been oft-injured throughout his minor league career and has shown a glaring lack of power outside of 2019’s juiced-ball season in Triple-A. He has strong bat-to-ball skills, striking out in just 14 percent of his career plate appearances in the minors, but the fact that he went unclaimed is indicative of concerns surrounding his overall game.
