[3] McClellan signed with the Cardinals after being drafted by the club in 2002 and made his professional debut with St. Louis' rookie franchise in Johnson City.

[7] In 2011, McClellan earned a spot in the starting rotation after Adam Wainwright was forced to miss the entire season for Tommy John surgery.

By September, arm fatigue set in and he was left off the Cardinals' divisional playoff and World Series roster.

Exploratory surgery indicated a frayed labrum and a split in the right shoulder capsule, both requiring months of rehab following surgical repair.

[10] On January 15, 2013, McClellan signed a minor league deal (with invitation to spring training) with the Texas Rangers.

McClellan made what would prove to be his final major league appearance on June 29, 2013, and was designated for assignment on July 2, 2013.
