The Rangers signed Joe Nathan last week, but they're still exploring ways of adding relief help, since they aim to enter the 2012 season with the strongest bullpen possible. They're one of the teams trying to trade for A's closer Andrew Bailey, according to Ken Rosenthal of FOX Sports. ESPN.com's Buster Olney notes that the Red Sox are also pursuing Bailey (Twitter link).
The 27-year-old right-hander posted a 3.24 ERA with 8.9 K/9 and 2.6 BB/9 in 41 2/3 innings in 2011 after recovering a forearm strain that sidelined him early in the season. MLBTR projects a $3.5MM salary for Bailey in 2012. One of Rosenthal's sources promised that the Rangers will add another reliever to join Nathan, Mike Adams and Koji Uehara at the back end of the bullpen. The Red Sox, who lost Jonathan Papelbon to the Phillies, also have interest in adding to the back end of their bullpen this offseason.
The Blue Jays, Mariners and Reds are also interested in Bailey, who appears to be available. The Rangers had interest in him leading up to last summer's trade deadline.
