#Brewers RHP Jesus Sanchez has been selected from Triple-A Nashville and added to the 40-man roster, which now stands at 37.— Mike Vassallo (@MikeVassallo13) October 17, 2012
Sanchez is a 25-year-old Venezuelan native who just wrapped up his fifth professional season. He appeared in 52 games between AA and AAA in 2012, posting a 1.63 ERA with eleven saves. He also struck out eight batters per nine innings while walking 2.8 and allowed just two home runs all season.
Sanchez was not eligible for minor league free agency but adding him to the roster protects him from this winter's Rule 5 draft, where a reliever coming off a sub-two ERA in the upper levels of the minors probably would have been a popular target.
The Brewers also cleared some space on the roster today by removing Livan Hernandez and Yorvit Torrealba. Both players refused outright assignments to the minors and are now free agents, but it's really just a paper transaction since they would've become free agents after the World Series anyway.
