Jeff Pentland played with Reggie Jackson and has tutored Barry Bonds, Sammy Sosa, Carlos Beltran and Matt Kemp, to name-drop just a few. He has advanced degrees in biomechanics. His playing days were on both sides of the chessboard; pitcher and hitter. What he doesn't know about the art/science of hitting may not be worth knowing.
No wonder the Dodgers fired him as their hitting coach last year.
It's not like there wasn't a precedent. But gurus like Pentland are never out of work any longer than they care to be. This year he signed on with the Seattle Mariners (again) as the hitting coach for their Triple A affiliate, Tacoma of the Pacific Çoast League. The Rainiers hit only .235 in April but this month they're banging away at a better than .300 clip and carrying a 13-game homer streak as Pentland settles in. He stepped away from the batting cage while the Rainiers are in Des Moines taking on the Iowa Cubs and talked with TCR.
