"The Oakland A's could be on the verge of signing free-agent pitcher Bartolo Colon, according to an ESPN report.

The 38-year-old Colon, who revitalized his career last year with the New York Yankees, is negotiating with the A's, ESPN's Buster Olney reported on Twitter Saturday.

Colon, who has pitched for six teams in his 14-year career, hadn't pitched in the major leagues since July 2009 when he made the Yankees' rotation last year, where he went 8-10 with a 4.00 ERA. Colon started 26 games and pitched 164 innings, allowing 172 hits, walking 40 and striking out 135.

Colon is 161-113 in his career, but he's gone just 22-31 since 2006."
