According to Martin Gallegos of MLB.com, the Athletics have designated right-handed pitcher Anthony Maldonado for assignment. This transaction opened the roster spot for right-handed pitcher Elvis Alvarado, who the team claimed off waivers earlier on Thursday. Prior to the designation, Maldonado was ranked as the No. 21 prospect in the Athletics system on MLB.com. The former 11th-round selection made his big league debut last season and held a 5.68 ERA with a 1.47 WHIP across 19 innings. He struck out 11 batters. He generated a 3.62 xERA, which suggests he should see some positive regression when he returns to the major leagues. In 46 1/3 innings at the Triple-A level last summer, Maldonado posted a 4.66 ERA and a 1.47 WHIP. Maldonado will likely open the 2025 season at the Triple-A level.

Miami Marlins right-handed pitching prospect Anthony Maldonado has been called up from Triple-A Jacksonville to start on Friday against the Washington Nationals after left-hander Jesus Luzardo was scratched after experiencing left-elbow discomfort. Maldonado, the team's No. 18 prospect per MLB Pipeline, will be making his major-league debut and won't be a recommended streamer for fantasy managers. The 26-year-old has posted a 2.31 ERA and 0.77 WHIP with 10 strikeouts and four walks in 11 2/3 innings at Jacksonville this year, but he hasn't gone more than two innings in any of his eight outings on the farm in 2024. Don't expect that to change in what will essentially be a bullpen game for the Fish to start the series against the Nats. Kyle Tyler is probably the best bet for the bulk role for Miami on Friday.
