2011-12: Limited to 36 games during the regular season due to knee problems, Tesink proved to be a valuable third line forward for the powerful Saint John Sea Dogs in the post-season. He scored 13 goals with 27 assists and was plus-23 with 54 penalty minutes during the regular season. In the Quebec League playoffs he scored 7 goals with 6 assists in 17 games and was plus-5 with 24 penalty minutes as Saint John won the QMJHL championship. While he was a forgettable minus-3 in the Sea Dogs’ 7-4 loss to QMJHL rival Shawinigan in the Memorial Cup semifinal, he scored three goals in four games at the tournament.
2012-13: Tesink began the season as an assistant captain for Saint John before a mid-season trade to Blainville-Boisbriand. At the time of the trade, he had 16 goals with 21 assists and was plus-3 with 75 penalty minutes in 35 games for the Sea Dogs. A chronic knee condition allowed him to play just six regular season games for the Armada (leading to a league hearing on the trade). He scored 1 goal with 3 assists and was plus-3 with 6 penalty minutes. Blainville-Boisbriand finished first in the West Division and reached the playoff semifinals. In four playoff games Tesink scored 1 goal and was minus-3 with 23 penalty minutes. He signed a three-year entry-level contract with St. Louis in March, 2013.

Alaska finished fifth in the West Division, missing the ECHL playoffs.
Tesink is used as an energy-line type who can fill a larger role when called upon to do so. He is only average sized but keeps his feet moving and plays with an edge. Tesink is a strong skater who dedicates himself equally to both ends of the ice. He's a tireless forechecker who will take a hit or a stick in the guts to make a play.
Tesink spent a second season in the ECHL in 2015-16, beginning the year with the Quad City Mallards and ending the year with Alaska. He is a willing combatant and has chipped in with supplementary offense but enters the final year of his entry-level contract still looking to crack the AHL level. His NHL potential appears limited.
