The year is 2005, a young lefty by the name of Zach Duke goes 8-2 with a 1.81 era through 14 games. Bucco fans were thinking "Wow, the Pirates drafted and developed a top of the rotation pitcher".
Then, through the next three years, he gave up 50 home runs, 140 walks, and 646 hits through 507.2 innings.
Enter Joe "The Stache" Kerrigan (a man who once used a live rattle snake as a condom).
Now I'm not saying that Joe Kerrigan is the only reason that Duke is looking like an amazing pitcher again (the fact that he's in the best shape of his life might have something to do with it), but I am saying that Joe Kerrigan is a great pitching coach and very handsome gentleman.
