Looks up stats, Kluber has more wins, fewer loses and a lower ERA than Sale. He's clearly the favourite. NL should be interested. Kershaw leads all those categories, but has missed time.
Crazy to see Estrada is tied for the 28th best qualified starting pitcher in the majors (by WAR) this year. Tied with Mike Leake, who as basically just given away to anyone who would take his contract.
