This past year, Mamula tutored two All-Region players: Tyler Frank and David Miranda. Frank (First Team), Jared Shouppe (Second Team) and Eric Rivera (All-Freshman) all earned Conference USA honors, while the team averaged seven runs a game while batting .289 with an even .400 on-base percentage. The Owls' 70 home runs was second in C-USA, and the squad also finished second with 286 walks versus just 350 strikeouts (second-lowest in the league). In DI, they finished among the top 25 teams in OBP, walks, home runs and hit-by-pitch (87).
In his first season at FAU, the Owls posted a 39-19 record, winning the Conference USA regular season title and earning the No. 2 seed at the Coral Gables Regional. The FAU offense averaged over six runs per game, hitting .288, having a .382 on-base percentage and hitting a league-leading 116 doubles. The Owls' offense was led by Conference USA Player of the Year CJ Chatham. Chatham, who was the second-round pick of the Boston Red Sox, hit .357 with a .422 on-base percentage, .554 slugging percentage and 50 RBI.
In addition to Chatham, two other Owls have moved on to professional baseball over the past two seasons: Stephen Kerr (Los Angeles Angels) and Billy Endris (Arizona Diamondbacks).
Prior to FAU, Mamula was an assistant coach at the University of Cincinnati. At UC he coached the offense, infielders, assisted with the recruiting and was the third base coach. In his first year as the Bearcats' hitting coach, the team batting average increased from .251 to .285, slugging percentage from .372 to .404, on-base percentage from .336 to .370, and runs per game from 4.94 to 5.56.
All of that improvement came despite it being the first season with the BBCOR bats and having graduated five senior hitters from the previous year. Mamula's recruiting efforts helped UC land its first ever first round draft pick with junior All-American outfielder Ian Happ being selected with the ninth overall pick by the Chicago Cubs in the 2015 MLB Draft. Happ made his MLB debut with the Cubs in 2017.
Before Cincinnati, Mamula was the head coach at NCAA Division II West Chester University of Pennsylvania for three years. During his tenure at West Chester, he averaged 41 wins per season while compiling an overall coaching record of 124-45 (.734).
Regarded as one of the top young head coaches in NCAA DII baseball, Mamula was named the PSAC East Coach of the Year and the Atlantic Region Coach of the Year in 2009, while his team finished the year ranked seventh in the nation after reaching the DII College World Series. It was only WCU's second ever appearance at the World Series. His 2009 team set the school record for wins in a season with 46, breaking the previous mark of 45 that they had set one year earlier.
Prior to hiring Mamula in the fall of 2006, West Chester had two NCAA Regional championship game appearances in its baseball program's history. Mamula led his team to the NCAA Regional championship game in each of his three seasons. His teams ranked among the best statistically in several offensive and pitching categories in all of DII baseball. Over his three seasons, the Golden Rams hit .334 and had a 3.66 team ERA.
Mamula mentored two Conference Players of the Year, two Conference Pitchers of the Year and one Conference Rookie of the Year, in addition to 29 All-Conference players, 13 All-Region players, four All-American performers and three MLB draft picks. WCU had not had a draft pick in the 12 previous MLB drafts. Included in Mamula's recruiting classes at WCU are current Oakland A's second baseman Joe Wendle, who made his MLB debut in 2016, and Baltimore Orioles pitcher Joe Gunkel.
Mamula's coaching resume also includes five years as an assistant coach and recruiting coordinator at the University of Delaware (2002-2006), and as an assistant for three years at Shippensburg University (1999-2001).
In his five recruiting classes at Delaware, Mamula brought in 20 All-Conference performers and two All-Americans, and 13 of his recruits were selected in the MLB Draft. In his final year at Delaware, the Blue Hens' offense led all of NCAA Division I baseball in home runs (111), doubles (143), and slugging percentage (.574).
As a player, Mamula was a four-year starter as an infielder at St. Bonaventure University, where he was an Atlantic 10 All-Academic Team selection his junior and senior seasons and served as team captain his senior year.
Mamula and his wife Melissa live in Boca Raton and have two children, Reid and Allison.
