Braves pitching prospect Arodys Vizcaino will miss the 2012 season after undergoing Tommy John surgery. Vizcaino underwent the surgery on Tuesday. Vizcaino had been rated as Atlanta's No. 2 prospect by MLB.com and the 36th-best prospect in all of baseball. After resting for six weeks in 2010, Vizcaino went to the instructional league and was throwing 98-mph fastballs. His elbow did not begin bothering him again until this year. He did not return to pitch after experiencing elbow discomfort during his March 3 appearance against the Tigers.
