"The Diamondbacks still are perusing the free-agent market for a veteran starting pitcher to compete for a spot at the end of their starting rotation, and right-hander Bartolo Colon appears to be their latest interest.

Nothing was expected to be solidified immediately, but a league source said the Diamondbacks have interest in the 16-year journeyman, who turns 39 in May.

Colon started 26 games last season for the New York Yankees, going 8-10 with a 4.00 ERA with 40 walks and 135 strikeouts in 1641/3 innings.

Colon became expendable to the Yankees after their acquisitions Friday night of Michael Pineda in a trade with the Seattle Mariners and free agent Hiroki Kuroda, whom the Diamondbacks courted for a time this off-season.

Colon didn't pitch in 2010 and underwent stem-cell treatment for injuries to his elbow and rotator cuff before signing a minor-league deal with the Yankees.

Though they have interest in Colon, a Diamondbacks source recently said the team still has interest in bringing back left-hander Joe Saunders, who was not offered salary arbitration."
