2009-10: A sixth-round selection (107th overall) in the 2009 OHL Priority Draft by the Niagara Ice Dogs, Phil Di Giuseppe chose to skate for the Villanova Knights in the Ontario Junior A Hockey League. In 56 games he scored 16 goals with 31 assists. The Knights finished seventh in the 15-team league. In six playoff games Di Giuseppe scored 1 goal with 3 assists.
2010-11: Di Giuseppe was the third-leading scorer for Villanova in his second season with the Knights. He scored 24 goals with 39 assists and had 25 penalty minutes. After finishing second in the South Division of the re-aligned OJHL, the Knights reached the Southeast Conference finals. In 10 playoff games Di Giuseppe led Villanova in scoring with 6 goals and 10 assists with 8 of his 10 points (3 goals, 5 assists) coming on the power play. Di Giuseppe committed to playing college hockey at the University of Michigan in 2011-12.
2011-12: Di Giuseppe skated in 40 of 41 games for the University of Michigan as a freshman. He scored 11 goals with 26 assists and was plus-23 with 18 penalty minutes. After finishing second in the CCHA, the Wolverines reached the finals of the league tournament and received an at-large bid to the NCAA Midwest Regional. Di Giuseppe was invited to the NHL Draft Combine but was not ranked among the 210 North American skaters in Central Scouting's final rankings prior to the 2012 NHL Draft.
2012-13: Di Giuseppe got off to a slow start in his sophomore season at Michigan in a rare losing season for the Wolverines. After starting the year with 3 goals and 8 assists through 22 games, Di Giuseppe scored 6 goals with 11 assists in the last 18 games. Michigan finished seventh in the CCHA and failed to win 20 games for the first time since head coach Red Berenson's third season in 1986-87.
A bulky player for his age, Di Giuseppe is one of Carolina’s premier offensive prospects. The University of Michigan star has a lot of things to work on to include shot placement and using size to his advantage, but he does have all the tools in place to become an important scoring threat on any team he plays for.
Di Giuseppe will enter his junior year at Michigan next season. Like most NCAA talents in the Hurricanes’ organization, he does not project to go pro until he is done with school.
