In December 2003, he was once more selected in the minor league portion of the Rule 5 draft, this time by the Tampa Bay Devil Rays.

Corcoran made his Major League debut on June 14, 2005[1] for the Devil Rays against the Milwaukee Brewers, working two scoreless innings of relief.

He went into 2006 spring training looking to stay in the majors, but was sent down to Triple-A to begin the season and not recalled until June 15 (due to an injury to closer Tyler Walker).

He started the 2007 season with Triple-A Durham and was recalled by the Devil Rays after Juan Salas received a 50-game suspension following a positive drug test.

On Jan. 4, 2008, he signed a minor league deal with the Florida Marlins, and spent most of the year playing for their Double-A team, the Carolina Mudcats.

He spent the entire 2011 season on the disabled list for Albuquerque after undergoing Tommy John surgery on his elbow.
