2008-09: Dylan Demelo played 74 games for the London Junior Knights midget minor team in Ontario. He scored 11 goals with 34 assists and had 46 PMs. He was selected by Mississauga St. Michael's in the 2nd round (34th overall) of the 2009 OHL Priority Draft.
2009-10: Demelo skated in 20 games for Mississauga St. Michael's in the OHL – spending most of the season with the Junior A Mississauga Chargers. He had 1 assist and was +3 with 12 PMs in limited ice time with the Majors. In 36 games for the Chargers he scored 9 goals with 20 assists and had 24 PMs.
2010-11: Demelo played in 67 of 68 games as Mississauga St. Michael's dominated the regular season in the OHL – winning 53 games. Demelo was +31 and scored 3 goals with 24 assists and 70 PMs. The Majors faced Owen Sound in an epic OHL final series, won by Owen Sound in overtime of the seventh game. Demelo was +10 in the playoffs with 1 goal, 4 assists and 15 PMs in 20 games. The Majors hosted the Memorial Cup and in five games during the tournament Demelo was scoreless with 4 PMs. Ranked 121st amongst North American skaters in Central Scouting's final rankings, he was selected by San Jose in the sixth round (179th overall) of the 2011 NHL Draft.
2011-12: DeMelo improved on his offensive numbers of last season for a much weaker Mississauga team while playing on both specialty units and big shutdown minutes. The defender scored seven goals (four on the power play and one shorthanded) along with 40 assists and a good plus nine rating while taking 70 PIMs in 67 games. DeMelo and the Mississauga St. Michael's Majors lost a very tight, physical first round OHL Playoff series 4-2 against the Barrie Colts. The physical offensive defender was only able to contribute a power play goal along with an assists and a minus three rating while taking 13 PIMs (one fighting major) in the series. The Shark were impressed enough to give the young defenseman an ATO to play for AHL Worchester for four games to end his year. He was a solid plus three rating with an assist in the four AHL games and the team signed to a three year NHL entry level contract.
2012-13: DeMelo skated in ten AHL games; joining the Worcester Sharks in April for the second straight season after playing in the OHL. He had 4 assists and was -1 with 6 penalty minutes. Worcester missed the AHL playoffs after finishing fourth in the Atlantic Division. DeMelo was the third-leading scorer for the re-christened Missisauga Steelheads, scoring 15 goals with 35 assists in 64 games while finishing -9 with 68 penalty minutes. The Steelheads reached the playoffs despite finishing under .500 and last in the Central Division. DeMelo scored 1 goal with 3 assists and was -5 with 6 penalty minutes in the six-game series with Belleville.
Demelo is a big strong puck-moving defenseman who likes to jump up into the play and shoot his big booming shot on the fly. He can play in all situations though he thrives in offensive situations because of his shot and hockey sense. He has a great hockey I.Q. and is not afraid of playing a simple unmemorable game if that is what it takes to win. Like with all young defensemen DeMelo’s main development hurdles will be strength related as he moves up from junior to the AHL and competes against men.
DeMelo got his first taste of AHL action last season in four games at season's end. He did not look out of place. He will likely play a bottom pairing role this season with Worcester as he eases into the professional game.
