The last six years for Peter Moylan have seen both extremes of health. In 2007, 2009, and 2010, he pitched at least 80 games each season and was a big part of Bobby Cox's bullpen with the Braves. But in 2008, 2011, and 2012, Moylan was limited to under 10 innings each year thanks to separate surgeries, including a Tommy John procedure in 2008. Moylan pitched just 13⅓ innings combined in the last two seasons.

"It was as frustrating a two years you could ever have," said the sidearmer from Australia.

Moylan had back surgery in April 2011 that caused him to miss 4½ months, then shortly after returning developed a torn labrum and rotator cuff in his shoulder that required surgery to knock him out for most of 2012. After getting non-tendered, Moylan signed a minor league deal with the Braves, and was determined to pitch again last season. He was promoted to the Braves in September.
