Tom Hutyler has been the Mariners' public address announcer since 1987, first at the Kingdome, and presently at Safeco Field. Spanish-language radio broadcast duties are handled by Alex Rivera on play-by-play and former second baseman Julio Cruz providing color commentary. Seattle radio personality Matt Pitman hosts the post-game show on the Mariners' radio network, along with clubhouse reporter Shannon Drayer. For the 2011 season, Dave Niehaus' duties in the broadcast booth are being filled by a collection of former Mariners broadcasters such as Ron Fairly, Ken Levine, and Ken Wilson and former Mariners' players such as Dave Valle, Dan Wilson, Jay Buhner, and Dave Henderson.

Niehaus, who had broadcast for the Mariners since their inaugural season of 1977, died on November 10, 2010.

For the first three innings of each game, Niehaus worked the television broadcast with Blowers, and Rizzs and Sims handled radio duties after the third inning, Niehaus and Sims traded places. The Mariners' broadcast team for 2010 featured Dave Niehaus and Rick Rizzs-back for their 32nd and 23rd seasons with the club, respectively-as well as veteran broadcaster Dave Sims and former infielder Mike Blowers. Selected Mariners games are also available on Canadian television, due to an agreement between Root Sports Northwest and Rogers Sportsnet. In years past, Mariners games have also appeared in Seattle on over-the-air stations KING-TV, KIRO-TV, KTZZ-TV, and KSTW-TV. Television rights are held by Root Sports Northwest. The Mariners' flagship radio station is KIRO-AM 710 (ESPN Radio), which previously broadcast Mariners contests from 1985–2002.
