Phillies righthander Scott Mathieson's big-league career is in peril.
He is scheduled to have his right elbow scoped Thursday, but is very likely to have his second Tommy John surgery in a little more than 19 months. Mathieson, who also had ulnar nerve transposition surgery Sept. 24 last year, hasn't pitched in the big leagues since Sept. 2, 2006.
Pitchers that have Tommy John surgery typically have an 80 to 90 percent success rate. Those pitchers that need the surgery again typically have only a 30 percent success rate. So Mathieson, the team's 17th round pick in 2002, has a long, hard road ahead of him.
