Bartolo Colon's days with White Sox appear to be over

Prior to tonight's game against the Seattle Mariners, the Chicago White Sox requested waivers on right-handed pitcher Bartolo Colon for the purposes of granting him his unconditional release.

Colon, 36, went 3-6 with a 4.19 ERA (29 ER/62.1 IP) in 12 starts for the White Sox this season. He has been on the disabled list since July 28 (retroactive to July 25) with right elbow inflammation.

The 5-foot-11, 245-pounder has gone 153-103 with a 4.10 ERA (945 ER/2,076.2 IP) in 328 games (325 starts) over 13 major-league seasons with Cleveland (1997-2002), Montreal (2002), the White Sox (2003, '09), Angels (2004-07) and Boston (2008).

Colon was signed by Chicago as a free agent on January 15.
