Bill Mosiello

Assistant Coach

First Year

Bill Mosiello, the newest addition to Auburn Head Coach Tom Slater's staff, is no stranger to the Southeastern Conference or success, which was exactly what Slater was looking for when he was searching for an assistant coach that shared his same aggressive offensive approach. When Mosiello was hired on June 28, 2007, he brought with him 16 years of collegiate coaching experience, four years of professional coaching experience and an attitude for mental toughness.

Mosiello came to Auburn after spending the 2007 season at Southern California as the hitting coach. In just one year in Los Angeles he helped shortstop Grant Green earn Freshman All-America honors as he hit .306 with 14 doubles, 10 triples, 24 RBI and six stolen bases to go along with a .966 fielding percentage.

Prior to USC, Mosiello spent four years as a member of the New York Yankees organization, including two as the manager for the Charleston RiverDogs, the Yankees' single-A affiliate of the South Atlantic League, where he posted a two-year record of 129-98 (.568). He also managed the Battle Creek Yankees in 2004 and spent a season as the hitting instructor for the Trenton Thunder (AA) in the Yankees system.

Prior to his minor league experience, Mosiello, 43, 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), won four South Coast Conference titles and two California state junior college championships.

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 `92, the Titans advanced to the College World Series championship game, featuring 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 SEC 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 Ole Miss 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 consecutive first-place finishes in the Big XII Conference. Offensively, none of his teams at Oklahoma hit worse than a .309 clip.

Mosiello then spent the 2001 season at Arizona State before joining the Yankees.

Mosiello 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 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.

Mosiello has earned Manager of the Year honors twice in the Alaska Summer League (1990, 1991) and once in the Cape Cod Baseball League (1998).

Mosiello and his wife, Janelle, have three sons; Shane (10), Gehrig (7) and Helton (1).

"I think Mo is one of the brightest, most highly motivated coaches I have been around in my 35 years in the business. He knows the game, he is relentless in his approach to teaching the game and is also a very solid evaluator of talent. He is going to bring a lot to Auburn's baseball program."
