Sorry for the self-promoting link, but this is the one place where there's a complete list of all the announcements with bios (no Augusta GreenJackets). There is just a single new face among the coaches, but a lot of shuffling between levels. Here's the list:
Fresno: Steve Decker-Manager; Pat Rice-Pitching; Russ Morman-Hitting
Richmond: Dave Machemer-Manager; Ross Grimsley-Pitching; Ken Joyce-Hitting
San Jose Giants: Andy Skeels-Manager; Brian Cooper-Pitching; Gary Davenport-Hitting
Augusta (Not official yet): Lipso Nava-Manager; Steve Kline-Pitching; Jose Flores-Hitting
Salem-Keizer: Tom Trebelhorn-Manager; Jerry Cram-Pitching; No Hitting Coach Announced (Derin McMains?)
And I was wrong from my earlier prediction about Augusta pitching coach Steve Kline moving up the system.
