2009-10: In a second OHL season, Gregg would suit up with Mississauga, though he would find season cut short by injuries. In his 43 games, the winger would be good for 8 points.
2010-11: Sutch played a two-way role and provided physical play in his second year with Mississauga St. Michael's. In 53 games, he scored 8 goals with 20 assists and had 79 PMs and was +20 on a Majors' team that had the top record in the OHL. In the post season, the Majors advanced to the playoff finals and competed in the Memorial Cup as the host team. In nine OHL playoff games, Sutch saw limited ice time after suffering a wrist injury and was scoreless and -1 with 4 PMs. He appeared in four of the Majors' five games at the Memorial Cup and was scoreless and -1.
Sutch is a physical winger who is relentless on the fore-check. He lacks much offensive upside but he makes up for it with grittiness and heart. He still needs to develop his skating and learn to control himself on the ice to eliminate some of the bad penalties he takes but he made strides in other areas during the 2010-11 season. His defensive game showed improvement and he posted career high totals in every statistical category. Sutch was traded during the off-season in 2011 from Mississauga to Barrie.
Sutch was not signed by the Sabres and was not chosen in the 2012 NHL Draft. He is now a free agent.
