Bill Mosiello was named Ohio State’s head baseball coach on June 16, 2022. He came to Columbus as one of the most accomplished assistant coaches in the country with stops at seven different Power 5 programs.

Mosiello was the associate head coach at TCU for nine seasons (2014-22) before coming to Columbus. He has nearly 30 years of collegiate coaching experience and seven more years of experience as a minor league manager. His talents were rewarded in the summer of 2017 as he was tabbed a coach on the USA Baseball 18U National Team in addition to being the 2018 16U NTDP head coach. Over the course of his career, Mosiello has coached over 90 major league players, 28 All-Stars, two batting title winners, two AL MVPs, one AL Rookie of the Year and 2012 Cy Young award winner R.A. Dickey.

At TCU, Mosiello helped guide TCU to four straight appearances in the College World Series (2014-17) and seven NCAA Tournaments. The Horned Frogs won seven Big 12 titles in his nine seasons and was the winningest baseball program in the country from 2014-17 with 199 total wins. Mosiello was also instrumental in recruiting three Top 10 classes in his time in Fort Worth.

One of the most respected offensive minds in the game, the Frogs have flourished under Mosiello’s guidance. The Horned Frogs led the Big 12 in batting average in two different seasons and ranked second among Power 5 schools with more than 800 stolen bases from 2014-22. Four times the Frogs surpassed the 100-stolen base mark over Mosiello’s tenure.

TCU ranked in the top 50 nationally in runs per game six times under Mosiello and along with the increased run production, TCU’s home run totals have climbed each season. The Frogs hit 65 in 2019, the most since the 2010 campaign and slugged 62 in his final season in 2022.

Prior to TCU, he spent two seasons at Tennessee serving as the recruiting coordinator and hitting instructor. In Knoxville, he helped recruit a top 20 class each season and coached 11 players drafted in the MLB draft in first year of eligibility.

Prior to his stint at Tennessee, Mosiello served as the manager of the Los Angeles Angels of Anaheim’s Double-A affiliate, the Arkansas Travelers where he tutored MLB phenom Mike Trout for nearly two full seasons.

Mosiello joined the Angels organization in 2009, spending his first two seasons as the manager of the single-A Cedar Rapids Kernels. He guided them to a 160-116 record (.580) during the 2009 and 2010 campaigns. Mosiello owns a career managerial record of 383-294 (.566) in the minor leagues, including his two years at Cedar Rapids and parts of three seasons in the New York Yankees organization from 2004-06.

Between his stints with the Yankees and Angels, Mosiello returned to the collegiate ranks as a hitting coach at USC in 2007 and at Auburn in 2008.

Prior to USC, Mosiello spent four years with 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).

Before beginning his minor league career, Mosiello spent 15 seasons in the collegiate coaching ranks. After the completion of his playing career at Fresno State in 1986, he began his coaching career at Cerritos College where he 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 1992, the Titans advanced to the College World Series championship game, featuring Golden Spikes Award winner and No. 1 overall draft selection Phil Nevin.

After his first two seasons at Tennessee (1993-94) and one season as the pitching coach at Ole Miss (1995), Mosiello spent five seasons (1996-2000) at Oklahoma with part of his tenure as associate head coach. The Sooners made three regional appearances and won the 1997 Big 12 Tournament. He then spent the 2001 season at Arizona State before joining the Yankees.
