I say yes, without question. His career stats and status are pretty prominent. He came in under 300 wins, but has a respectable career ERA despite some bad seasons early in his career, and over 3000 strikeouts. He had some tremendous seasons and put out a consistantly dominant performance.
He's also one of the best control pitchers of all times, with a strikeout to walk ratio that only Pedro Martinez and Greg Maddux really compare to.

I'd say looking just at his regular season accomplishments he's worthy, but arguable. But his post-season statistics and legacy put him over the edge.
Possibly the greatest post-season pitcher of all-time. His stats are insane. They're even more impressive if you take into account that they're skewed by that one bad outing against the Yankees when he was injured.
He came back from it with the legendary bloody sock game, which is one of the classic baseball moments. I'm a homer though.

Still, don't know how this is even a question among the voting sports media.
