Starting pitcher
Several Major League Baseball players, especially pitchers, have been diagnosed with thoracic outlet syndrome, including Chris Archer, Matt Harvey, Chris Carpenter, Jaime Garcia, Shaun Marcum, Matt Harrison, Clayton Richard, Nate Karns, and Noah Lowry. Starting pitcher Chris Young, who previously struggled with shoulder problems, underwent surgery for TOS in 2013 and felt "completely different" post-recovery. Young exceeded expectations on his return to the major leagues at age 35, becoming a valuable member of the 2014 Seattle Mariners' starting rotation.
