The Toronto Blue Jays picked up right-handed pitcher Carlos Villanueva from the Milwaukee Brewers for a player to be named later.
The 27-year-old appeared in 50 games for the Brewers in 2010, going 2-0 with one save and a 4.61 earned-run average.
He struck out 67 while allowing 48 hits and 22 walks in 52 2/3 innings.
Villanueva has a career record of 20-24 with six saves and a 4.34 ERA in 230 games, 27 starts, over five seasons with the Brewers.
He will probably fill one of the holes with the expected departure of relievers Kevin Gregg and Scott Downs, who became free agents after declining salary arbitration from the Blue Jays.
