Braves pitcher Shelby Miller said that he added about 15 pounds over the offseason. 

Miller was at 215 pounds last season, when he went 10-9 with the Cardinals. Dealt to the Braves in the offseason for Jason Heyward, Miller has bulked up. 

"I feel stronger ... more poise," he told MLB.com's Kevin McAlpin.

Miller has a 6.14 ERA in three games this spring.
