Looking for Veteran SP

[ballmark]

Looking for a veteran SP to replace Pep Canseco at the back end of my rotation for next year. Pep (7-0) is having a great year and I feel no need to move him this season, but wouldn't mind dealing for a Mentor to replace him come 2166. I've put a couple of players too old to be called prospects but could slide in well on someone's major league bench (for a contender) or play full time for a rebuilding club to offer in this deal.

Thank you, Blooms!
