2010-11: Matt Mistele skated for the Whitby Wildcats midget minor AAA team in Ontario. He scored 43 goals with 34 assists and had 50 penalty minutes in 60 games. Mistele was selected by Plymouth in the second round (33rd overall) of the 2011 OHL Priority Draft.
2011-12: Mistele skated in 12 of 13 playoff games for Plymouth after seeing limited ice time with the Whalers during much of his first OHL season. In 28 regular season games he scored 3 goals with 2 assists and was +2 with 33 penalty minutes. The Whalers finished first in the West Division and reached the second round in the playoffs. Mistele scored 2 goals with 3 assists and was +1 with 11 penalty minutes in the playoffs.
2012-13: Mistele led the Whalers with 34 goals and was one of three players to skate in all 68 regular season games in his second season with Plymouth. He finished +32 and had 26 assists and 69 penalty minutes as Plymouth again finished first in the West Division. The Whalers reached the Western Conference finals against OHL champion London. Mistele appeared in 9 of 15 playoff games — receiving a six-game suspension for a hit to the head in the first round against Sarnia. He scored 3 goals with 2 assists and was an even plus/minus with 8 penalty minutes in the playoffs.
2013-14: Mistele returned to Plymouth for his third season with the Whalers. The team’s fifth-leading scorer despite missing time early in the season due to a suspension, he scored 18 goals with 19 assists in 56 games and was -4 with 59 penalty minutes. Plymouth finished fourth in the West Division and lost to eventual OHL champion Guelph in a first round series. Mistele had 2 assists and was -3 with 2 penalty minutes in five playoff games. He was selected to play for Team Cherry in the 2014 CHL/NHL Top Prospects Game. Mistele was ranked 88th amongst North American skaters in the Central Scouting final rankings and was selected by Los Angeles in the sixth round (180th overall) in the 2014 NHL Draft.
Mistele has the prototypical size and attitude of a power forward and is an opportunistic goal scorer. His game fits in well with the hard edge, combative style that the Kings play as he is willing to go into the smaller areas and along the walls to retrieve the puck. His mobility and agility are areas that need to continue to improve for him to compete successfully at the NHL level. Mistele can be undisciplined in his exuberance at times.
Mistele attended training camp with the Kings before being returned to Plymouth at the start of the 2014-15 season. He was an assistant captain and among the leading scorers for the Whalers, who struggled out of the gate, and was acquired by Oshawa at the OHL trade deadline in January 2015. The Generals have been one of the league's top teams and are hoping the addition of Mistele bolsters their OHL and potential Memorial Cup prospects. He has yet to sign a contract with the Kings, who hold his rights until June 2016, and is eligible for an overage OHL season in 2014-15, though it is likely he signs and plays minor league hockey next year. Long-term, he projects as a second or third line two-way forward capable of providing supplementary scoring at the NHL level.
