The Red Sox have hired former San Diego Padres hitting coach Dave Magadan, but have not announced what specific job he will have (it may not be in Boston).
A SoSHer dug up these quotes:
Kevin Towers in 2003: "Magadan is fully aware of the importance of getting a good pitch to hit and constantly stresses patience at the plate. He has been outstanding and should be a great teacher for many years."
A Baseball Musings post from David Pinto: "One thing I liked from this is using hitting coach Dave Magadan to make the players more selective at the plate. ... His approach to hitting is excellent, and it will be interesting to see how he performs as a hitting coach."
