Born in Christina Lake, BC, Kevein Sawyer played in the Kootenay and BC junior leagues then moved up to the Spokane Chiefs of the WHL in 1992-93. After three seasons in Spokane, Sawyer signed as a free agent with the St. Louis Blues midway through the 1994-95 WHL season. A rugged hard-nosed player who doesn't shy away from the physical game, Sawyer joined the IHL's Peoria Rivermen following his season in Spokane before splitting the 1995-96 season with the AHL's Worcester IceCats and St. Louis.
After beginning the 1995-96 season with the Blues organization, Sawyer was traded to the Boston Bruins and split the remainder of the season between Boston and the team's AHL affiliate in Providence. Apart from four games, Sawyer was basically a farmhand on the Bruins. In 1997-98 he led the IHL with 398 penalty minutes as a member of the Michigan K-Wings. He signed with the Phoenix Coyotes as a free agent in August, 1999 but was only recalled for three games and spent the better part of the season with the AHL's Springfield Falcons. Following a one year stint with the Coyotes organization, Sawyer joined the Anaheim Mighty Ducks in the summer as a free agent.
Over the next three seasons, Sawyer has seen more playing time and managed to score his first ever NHL goal during the 2001-02 season.
