Martinez returned to the Blue Jays' broadcast booth in 2010, this time as a play-by-play announcer for their sister company and exclusive broadcaster, Rogers Sportsnet, replacing Jamie Campbell, who now hosts the pre-game telecast. His main broadcast partner on Sportsnet is former Blue Jay Pat Tabler. With Shulman's part-time return to the Blue Jays broadcast team in 2016, Martinez now splits duties between play-by-play and color analyst. On September 25, 2014, Rogers announced Martinez had signed a five-year extension to remain the play-by-play announcer for Toronto.
