The Diamondbacks are showing interest in free agent starter Bartolo Colon, ESPN.com's Jayson Stark tweets. Mitch Frankel represents the veteran right-hander, who could also be an option for the Yankees.
Colon posted a 4.00 ERA with 7.4 K/9 and 2.2 BB/9 in 164 1/3 innings with the Yankees in 2011. The 38-year-old signed a minor league deal with New York last offseason and thrived at the back of the team's rotation, especially early on in the season. Colon, who didn't pitch in MLB in 2010, has been treated with stem cells from his bone marrow and fat to repair tears in his elbow and rotator cuff.
