Frk's reputation as a scorer began during his time with Halifax in the Quebec Major Junior Hockey League. In his three seasons there from 2010-13, he had 73 goals in 152 games including 35 goals and 84 points in 56 games in 2012-13, when he also had 33 points in 17 playoff games. That same season, Frk helped Halifax win the Memorial Cup.
The Red Wings, who selected Frk in the second round (No. 49) of the 2012 NHL Draft, signed him to a three-year, entry-level contract a month later. He spent the next three seasons with Grand Rapids of the American Hockey League and Toledo of the ECHL.
