Piche, 23, has spent the majority of his sophomore pro season with the Walleye, appearing in 48 games. He ranked among the top ECHL blueliners this season with 12 goals (T4th) and 33 points (T10th), while finishing second among Walleye defensemen in points and ranking among the team’s overall leaders in goals (T6th), assists (21, 8th), points (9th) and power play tallies (8, 2nd). A native of La Sarre, Quebec, Piche also shows two assists and 13 PIM in 11 contests with the Griffins.
