The Houston Astros claimed the right-hander on outright waivers Saturday, the Twins announced. Deduno appeared in 30 games this season for Minnesota, including eight starts. He was 2-5 with a 4.60 ERA in 92 innings.
With Deduno gone, the Twins’ 40-man roster is now at 37 players. That could come into play in the next few days when Minnesota looks to make call-ups when the rosters expand in September.
To take Deduno’s spot on the 25-man roster, the Twins will select the contract of left-hander Aaron Thompson from Triple-A Rochester before Sunday’s game in Baltimore. Thompson, 27, has pitched in four career major-league games with Pittsburgh back in 2011. In 46 relief appearances with the Red Wings this year, Thompson was 3-3 with a 3.98 ERA in 52 innings.
Deduno, 31, began his career with the Colorado Rockies in 2003 as an amateur free agent. The Dominican Republic native made his major-league debut in 2010 with the Rockies as a reliever. He pitched in two games for the San Diego Padres in 2011, and made his Twins debut in 2012. In three seasons with Minnesota, Deduno was 16-18 with a 4.26 ERA in 63 games (41 starts). He had pitched primarily as a starter for the Twins until this season, when he was moved to the bullpen.
It remains to be seen whether the Astros intend to use Deduno as a starter or a reliever. Though he possesses intriguing stuff and a fastball with plenty of movement, control has been an issue throughout his major-league career. He averaged 4.4 walks per nine innings throughout 69 big-league games.
