Bill Mosiello begins his first season at USC after serving as the manager for the Charleston RiverDogs, the New York Yankees' single-A affiliate of the South Atlantic League. He spent four seasons with the Yankees' organization, posting a 129-98 (.568) record in two years as the RiverDogs' manager.
Prior to his minor league experience, Mosiello, 41, spent 15 seasons in the collegiate coaching ranks. After graduating from Fresno State in 1986, he began his coaching career at Cerritos College and posted a 163-34 record in four seasons (1987-90). He won four South Coast Conference titles and two California state junior college championships.
He has earned Manager of the Year honors twice in the Alaska Summer League (1990 and 1991) and once in the Cape Cod Baseball League (1998).
Mosiello made the move to the Division I level in 1991, joining Augie Garrido's staff at Cal State Fullerton where he spent two seasons (1991-92). In 1992, the Titans advanced to the College World Series championship game, falling to Pepperdine, 3-2. The 1992 squad featured Golden Spikes Award winner and No. 1 overall draft selection Phil Nevin.
In 1993 and 1994, he served as Rod Delmonico's assistant at Tennessee, where the Volunteers claimed consecutive Southeastern Conference championships. Future major leaguers R.A. Dickey and Todd Helton earned All-America recognition and were first-round draft picks.
After one season as pitching coach at Mississippi in 1995, Mosiello spent five seasons (1996-2000) at Oklahoma with part of his tenure as associate head coach. At Oklahoma, the Sooners posted several top finishes in the final national and conference fielding rankings, including a streak of three straight first-place finishes in the Big 12 Conference. Offensively, none of his teams at Oklahoma hit worse than a .309 clip. He was a volunteer assistant coach at Arizona State in 2001 before joining the Yankees.
During his tenure with Battle Creek in 2004, he compiled a 59-50 record.
He was tabbed by Baseball America as one of the nation's top assistant coaches after guiding 24 All-Americans and 12 first round major league baseball draft picks. He has managed or coached over 50 players during his career who have played in the majors, including Nevin, Helton, Sean Casey, Craig Counsell and David Dellucci.
