Bill Mosiello joined the coaching staff in the summer of 2013. Named associate head coach, Mosiello assumed the role of hitting/offensive coach and serves as the third base coach during games.

Mosiello came to TCU after spending two seasons at Tennessee serving as the recruiting coordinator and hitting instructor. He has over 20 years of collegiate coaching experience and seven more years of experience as a minor league manager.

"Bill is considered one of the best teachers of the game of baseball at any level," said Schlossnagle. "His experience throughout not only college baseball but as a manager of successful minor league teams will truly help elevate the development of our players.

"He brings relentless energy every single day. I look forward to our offense developing that kind of identity."

Since his arrival on campus, Mosiello helped guide the team to four straight appearances in the College World Series. One of the most respected offensive minds in the game, the Frogs have flourished under Mosiello's guidance. The Horned Frogs have led the Big 12 in batting average in two of the last four seasons. Additionally, TCU has become one of the top base-running teams, ranking eighth nationally with 499 stolen bases over the last five campaigns. Twice the Frogs have surpassed the 100-stolen base mark.

The Frogs are averaging 5.9 runs per game over the last five seasons. They have ranked in top 50 nationally in runs per game in four of the last five campaigns. Along with the increased run production, TCU's home run totals have climbed each season, reaching 58 in 2017, the most since the 2010 campaign.

In his first season on campus, TCU ranked in the top half of the Big 12 in all offensive categories. The group stole 93 bases, the most of any TCU team coached by Schlossnagle. A new approach at the plate helped the group boast a .368 on-base percentage, up 33 points from 2012.

The team batting average ballooned 32 points and ranked in the top 100 nationally. Five Frogs put together career years at the plate. Cody Jones swiped 29 bases to rank 13th nationally. All eight position players earned all-conference accolades.

Those improvements carried over to the 2015 campaign as the Frogs led the Big 12 in batting average and ranked 79th nationally with a .285 mark. For just the fourth time in school history, TCU swiped over 100 bases, finishing with 119 to rank fifth nationally.

Eight members of the starting lineup earned all-conference accolades, while Cody Jones became the first Horned Frog since 1999 to earn league Player of the Year honors. Jones was also honored as an All-American by various publications after a season in which he paced the Frogs with a .353 batting average and 33 stolen bases.

In addition to his efforts at the plate, his guidance came through on the defensive side as well. The Frogs ranked eighth nationally with a school-record .979 fielding percentage.

With a brand new lineup that at any given time featured five newcomers, the Frogs didn't miss a beat in 2016. For the second straight season, TCU paced the Big 12 in batting average (.302). The Frogs doubled their home run output in 2016, hitting 55, the most since the 2010 campaign. A pair of freshmen, Luken Baker and Josh Watson, led the team with 11 home runs each. TCU once again paced the league with 97 stolen bases.

A group of familiar faces in 2017 led to a preseason No. 1 ranking. The group lived up to its billing, reaching the CWS for the fourth straight year. Once again, the Frogs scored runs at a high rate thanks to another 100-stolen base campaign (108), a mark that ranked seventh nationally, and 58 home runs. Additionally, TCU drew 354 walks to rank fourth nationally. Evan Skoug became TCU's first 20 home run guy since the 1997 campaign en route to earning Big 12 Co-Player of the Year accolades. Six everyday players earned all-conference accolades.

"I am both extremely honored and blessed to have the honor to be named associate head coach by Jim Schlossnagle," said Mosiello. "The last two days, my wife and I have had opportunity to travel to Fort Worth and to meet with Chris Del Conte. I am very impressed with the support staff and administration that is in place at TCU. I have no doubt in my mind that it will be a great fit for my family and I to move to Texas. It's with a heavy heart that I leave Tennessee and a staff full of life-long friends, but my new position will fully allow me to utilize my strengths as a coach.

"From afar I have witnessed Coach Schlossnagle's career at TCU," continued Mosiello. "I am very impressed with what he's accomplished. It's a great privilege to have the opportunity to work with who in my opinion is one of the top pitching coaches in the country in Kirk Saarloos. Hopefully along with myself, him and I can become one top assistant coaching duos in the country."

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.

"When you look at players like Mike Trout and Todd Helton, and see that a big part of their development and success as professional players can be attributed to their work under Coach Mosiello, you have to be excited for our players to get to work along side him," said Schlossnagle. "He fits our mold of selfless, energetic people that are committed to excellence."

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 Southern California in 2007 and at Auburn in 2008.

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.

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 `92, 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 two years 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. He then spent the 2001 season at Arizona State before joining the Yankees.

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, Gehrig and Helton.
