The Nationals announced that they’ve claimed right-hander Rogelio Armenteros off waivers from the Diamondbacks. Arizona picked up the righty in a waiver claim of their own after the Astros tried to pass him through outright waivers earlier this winter. Washington’s 40-man roster is at 34 players.
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.
Though the elbow procedure creates some uncertainty, it’s clear that Armenteros is still viewed as an intriguing depth option with some upside, as we’ve now seen a pair of clubs claim him this winter. He does have a minor league option remaining, which surely appealed to the Nats, who have some uncertainty at the back of their rotation. After Max Scherzer, Stephen Strasburg and Patrick Corbin, the Nats don’t have set fourth and fifth starters. Armenteros will join a group of candidates that includes Erick Fedde, Joe Ross and Austin Voth — assuming the Nats opt to carry Armenteros on the roster for the remainder of the offseason, of course.
