In the last 15 years, the Dodgers have had 10 hitting coaches.

Mark McGwire makes 11.

That's a coaching revolving door that even the late Yankees owner George Steinbrenner would admire. The Dodgers tried a Hall of Famer (Eddie Murray) as hitting coach and a former player who never reached the Major Leagues (Jeff Pentland). They tried a former villain (Jack Clark '85) and a Yankees legend they later promoted to manager (Don Mattingly).

And now they've turned to McGwire to duplicate the success he had in St. Louis, where he adapted equally to a proven masher like Albert Pujols and youngsters like David Freese, Allen Craig and new Dodger Skip Schumaker.

McGwire follows Dave Hansen, who was not retained after the Dodgers' offense finished 13th in runs scored last year, a season in which the best hitter (Matt Kemp) was injured and an in-season influx of All-Stars made little impact. McGwire has the advantage of a loaded lineup to work with from the get-go, featuring five All-Stars.

One of his early projects is to figure out why Andre Ethier has forgotten how to hit left-handed pitching. Last year, Ethier hit .284 on the season, but .222 against lefties and 103 points higher against righties and a 339-point differential in OPS against right-handers versus left-handers.
