Bailey has played for the Oakland Athletics, Boston Red Sox, New York Yankees, Angels and Philadelphia Phillies in his career. He was a dominant force in his first two seasons with Oakland and made the 2009 and 2010 All-Star Games.
He won the 2009 American League Rookie of the Year behind a 1.84 ERA, 0.88 WHIP and 91 strikeouts in 83.1 innings. He also notched 26 saves in the process. He followed that up with a 1.47 ERA, 0.96 WHIP, 42 strikeouts and 25 saves in 49 innings in 2010.
However, injuries sapped him of much of his effectiveness after those initial two years.
Peter Abraham of the Boston Globe chronicled his physical ailments before the 2012 season and said Bailey underwent thumb surgery in 2012, suffered a forearm injury in 2011, had elbow surgery in 2010 and had knee surgery after the 2009 season.
What's more, he underwent season-ending surgery to repair a torn labrum in 2013 and didn't make a single appearance in 2014 as a result. He pitched in just 8.2 innings in 2015.
Bailey's numbers were still solid in 2011, but he was plagued by inconsistency and a couple of lackluster seasons after that:
|Andrew Bailey's Career Stats|
|2012||Boston Red Sox||15.1||7.04||1.89||14||6|
|2013||Boston Red Sox||28.2||3.77||1.22||39||8|
|2015||New York Yankees||8.2||8.31||1.73||6||0|
|2016||Philadelphia Phillies/Los Angeles Angels||43.2||5.36||1.33||41||6|
The silver lining for Bailey is his performance with the Angels last year. His overall numbers left much to be desired because of a 6.40 ERA in 33 appearances for the Phillies, but he sported a 2.38 ERA, 0.97 WHIP and six saves in 11.1 innings down the stretch for Los Angeles.
While they weren't pressure-packed appearances for a team well out of playoff contention, the positive results were a welcome sign for the 32-year-old veteran.
The hope for Los Angeles is that foreshadowed a return to prominence for the two-time All-Star and wasn't just a small-sample blip. The injury concerns are still quite real, but the chance Bailey finds his form again makes this a high-upside deal.
