Jenkins had a .900 OPS season in 2003 with Butch. Age is why Jenkins sucks, not Wynegar. And Bill Hall hasn't improved that much. Hitters are what they are, and no hitting coach is going to stop players like Jenkins and Hall hacking approach at the plate. That's just how it is. Jenkins has always swung at pitches in the dirt, no matter who the coach was, be it Jackson, Lefebvre, Carew, or anyone. EDIT: And Wynegar didn't "suck" as a hitter. He was pretty good. He won ROY, walked a ton, made a couple All-Star teams, and posted a career line of .255/.348/.347, with a 626/428 BB/K ratio. He also posted an OPS+ of 100 or more in six different seasons, and a 93 mark for his career, meaning he was a little below average.
