OAKLAND -- A's right-hander Fernando Rodriguez underwent shoulder surgery Friday to repair a complete tear of his lat tendon.
Rodriguez is expected to be able to begin a throwing program in four months, based on normal practice for such a surgery, which is considered rare.
Dr. Anthony Romeo orchestrated the procedure in Chicago, repairing a tear in the pitcher's latissimus dorsi tendon and performing a debridement on his teres major tendon.
Romero executed the same operation in July 2010 on Giants right-hander Jake Peavy, who was considered to be the first Major Leaguer to fully tear the tendon, which connects the lat muscle to the humerus bone.
