Assisting the student-athletes primarily with hitting and fielding, which were strengths of Pappas' game as a player, he earned a ring as Seton Hall won the 2011 BIG EAST Championship.
Last season, Pappas' Pirates finished second in the BIG EAST Conference with a team batting average of .273.
In 2014, thanks largely to Pappas' influence, Seton Hall led the BIG EAST in team batting with a .297 average. The Pirates also led the newly-reconstituted conference in slugging percentage, runs scored, triples, RBIs and stolen bases. In the field, Seton Hall's .975 fielding percentage was second-best in the league. The Pirates committed only 52 errors in 54 games.
In 2013, Pappas' coaching was evident as the Pirates finished the season as the second-best hitting team in the BIG EAST and the top fielding program in the conference. Seton Hall's .301 team batting average in 2013 was the highest since collectively batting .313 in 2000. The Pirates' .978 fielding percentage led the BIG EAST and their 48 errors was 18 less than the second-fewest (Villanova - 66) total in the league.
In 2011, Pappas managed the Monmouth Monarchs of the Atlantic Baseball Confederation Collegiate League to its first-ever league championship.
