Bob Guerriero joined St. John's in August of 2012 as an assistant coach for the softball team and is in charge of the outfield and hitting, while assisting in recruiting and administrative tasks. Prior to St. John's, he served in the same capacity at Seton Hall University.
During the 2014 season, Guerriero helped tie a program record .276 batting average on the way to the first ever BIG EAST Softball Championship in St. John's history. Over its 51 games, the St. John's starting four outfielders only committed 10 errors in 159 chances while recording 140 putouts and nine assists.
In his first season with St. John's, the Red Storm finished with a .249 team batting average, .373 slugging percentage, and .310 on-base percentage. Four members of the 2013 squad finished the season with a .340 average or better while Chrissy Montez became the new St. John's home run leader with 16.
During his time with the Pirates, Guerriero directed and implemented infield and outfield strategies, worked with the pitchers as required, assisted the head coach in all aspects, served as a base coach and performed several other vital administrative functions that helped SHU to five BIG EAST Championship appearances, including titles in 2004 and 2005.
During his early years at Seton Hall, Guerriero also served as the Coach and President of the Girls Softball League of Westfield in Westfield, N.J. From 1992-2004 he served as the Parkway Invitational Softball League Director, coaching several travel team squads during that time.
After a four-year career as a starting pitcher at Kean University - where he served as captain and was an All-NJAC honorable mention - Guerriero played three summers of semi-professional baseball.
