SAN FRANCISCO -- In the past two seasons, the Giants Minor League system has been the envy of most big league clubs, ranking third in baseball with a .553 organizational winning percentage, trailing only the Yanks (.555) and Tigers (.554).
Because of that success, four managers have been retained for 2007: Dave Machemer enters his third season at Double-A Connecticut, Lenn Sakata hopes to lead Class A San Jose to its fourth playoff appearance, Roberto Kelly takes the reins for Class A Augusta for a third time and Steve Decker will command short-season Salem-Keizer for a third straight season.
Also joining the coaching ranks will be former Giants star J.T. Snow, who'll coach during Spring Training.
Sakata led his club to the California League title in 2005, while Kelly was named South Atlantic League Manager of the Year in 2006 for guiding his team to the best record in Minor League ball (92-47). Decker earned co-Manager of the Year last season in the Northwest League with his team's franchise-best 55-21 mark and league championship.
At Triple-A Fresno this coming season, former Major League infielder Dan Rohn will manage the Grizzlies for the first time, joined by pitching coach Mike Caldwell and hitting coach Jim Bowie. Former Fresno skipper Shane Turner is now a roving outfield and baserunning coach.
The Arizona rookie level manager is Bert Hunter, assisted by pitching coach Will Malerich and hitting coach Victor Torres.
Also at Connecticut, coaches are Bob Stanley, pitching, and Gary Davenport, hitting. San Jose mentors are pitching coach Jim Bennett and hitting coach Andy Skeels. Jerry Cram (pitching) and Ricky Ward (hitting) are the coaches at Salem-Keizer, while Jim Bennett and Garrett Nago are coaches at San Jose.
Augusta features pitching coach Ross Grimsley and hitting coach Andy Skeels.
Head athletic trainers are Jim Simmons, Fresno; Anthony Reyes, Connecticut; Yukiya Oba, San Jose; Dustin Leupker, Augusta; Jonathan Kotredes, Salem-Keizer; and Eric Ortega, Arizona.
Roving instructors include Fred Stanley, coordinator; Bert Bradley, Minor League pitching coordinator; Bob Mariano, Minor League hitting coordinator; Joe Amalfitano, roving infield instructor; Jose Alguacil, roving infield instructor; Lee Smith, roving pitching instructor; Kirt Manwaring, Spring Training catching instructor; Jay Williams, coordinator of Minor League trainers; and Ben Bush, coordinator of Minor League strength and conditioning.
