Martinez -- a former catcher for the Jays and Toronto's manager for parts of the 2001-02 seasons -- takes over the role previously held by Jamie Campbell. After five years serving as Sportsnet's play-by-play man, Campbell will be reassigned to a new role with the station.
Martinez joins Rogers Sportsnet after serving as a color commentator for Baltimore Orioles broadcasts on MASN for the past seven seasons.
"I'm excited to join the Sportsnet team," Martinez said in a release. "I'm really looking forward to the opportunity to call play-by-play, and living up to the great tradition that has been established by Tom Cheek, Jim Hughson and Dan Shulman."
Martinez enjoyed a Major League playing career that spanned across 17 seasons, during which he had stints with the Royals, Brewers and Blue Jays. From 1982-86, Martinez spent the final six years of his catching career with Toronto. As a manager for the Jays, Martinez guided the club to a 100-115 record over parts of two campaigns.
After shifting into broadcasting, Martinez earned an Emmy Award for Best Sports Special in 1995 for his part in ESPN's airing of the game Cal Ripken Jr. breaking Lou Gehrig's record for consecutive games played. Beyond working as an analyst for ESPN from 1992-2000 and 2002-07, Martinez has served as a co-host of a morning show on XM Satellite Radio's Home Plate Channel for the past five years.
"Buck brings a passion for the game and our profession" Rick Briggs-Jude, vice president of production at Rogers Sportsnet, said in a release. "He has grown into a polished, accomplished and complete broadcaster. I am thrilled to add him to our broadcast crew."
