2008-09: Played for the US NTDP Under-17 squad. In 42 games vs. NAHL competition, Tinordi scored 2 goals and added 13 assists for 15 points.
2009-10: Captained the US NTDP Under-18 team that competed in the USHL. In 56 games for that team, Tinordi scored 5 goals and added 8 assists for 13 points while tacking on 95 penatly minutes. Tinordi won a gold medal as a member of the Team USA squad at the 2010 Under-18 World Junior Championships.
2010-11: Tinordi had an up-and-down season in his first year with the OHL's London Knights. After originally committing to play college hockey at Notre Dame, he signed with the Knights in hopes of accelerating his timeline to pro hockey. In 63 games with the Knights he led the team in penalty minutes (140) while scoring 1 goal with 13 assists and had a -8 plus/minus. Tinordi showed improvement through the course of the season and in the Knights six-game first-round playoff loss to eventual OHL champion Owen Sound he was a physical presence. Stat-wise he was scoreless in the series with a -1 plus/minus and 17 PMs.
2011-12: After a successful 2011 NHL training camp with the Montreal Canadiens, Tinordi returned to his OHL London Knights where he was named the team's captain for the 2011-12 season. The big blueliner started the season by showing grit, strong character and leadership while throwing punishing bodychecks and standing up for his teammates on the needed occasions. He missed ten games due to an eye injury suffered in a fight on Oct 14th, but still put up solid numbers, scoring two goals with 14 assists and a league best plus 39 rating and 63 PIMs (two fighting majors) in 48 OHL games. The American-born, Tinordi was chosen to play for Team USA at the 2012 World Junior Championship tournament where he was one of the better defensemen on an underperforming U.S Team. Tinordi and his Knights lost in over-time of the 2012 Memorial Cup finals against Shawinigan after beating the talented Niagara Ice Dogs 4-1 in the OHL finals for the Roger Championship to get to the Memorial Cup. The young Knights team put together a good playoff run of 16 wins with only three losses on their way to winning the OHL championship. The big defender also contributed three goals (one game winner) along with five assists and had an incredible plus 15 rating in 19 playoff games.
Tinordi possesses multiple talents that cannot be learned, such as an NHL pedigree and gargantuan stature. When at his best, he makes a habit of overpowering his opponents. He thrives when protecting the area around his net and in the corners. Tinordi skates well for his size, brings grit and toughness in the mold of a defensive defenseman, as well as leadership capability.
It just takes a long time to develop a big defenseman of Tinordi's size and he should spend at least one full year at the AHL level. He has played his final season in the OHL and will be starting his professional career most likely in the AHL for Hamilton this upcoming season.
