Below are some quotes from the mlb.com article. Sounds like the same stuff that's said about another hitting coach we all know.
"We think the world of Mickey Hatcher -- his work ethic, his enthusiasm for doing the job," Dipoto said. "But at a certain point, it becomes about the results on the field. Offensively, we're having a difficult time getting on base, we're having a difficult time hitting in situations, with runners in scoring position, etc., on down the line. We're all accountable. ... I'm included in that, Mike's included in that, obviously, Mickey's included in that, and this is a move that we're making in an attempt to jump-start an offense and to instill a philosophy that we believe has the power to last."
Hatcher was a target of a large segment of Angels fans who were irate about the club's offensive struggles, but players constantly praised his work ethic. "You will not find a harder working or more caring coach than Mickey Hatcher," Mark Trumbo posted on his Twitter account. "Always had my best interest at heart and brought great energy."
