In the early 1980s he was a sports reporter for the short lived "Satellite News Channel". Moving to radio, Sims became the host of WNBC'sSportsNight (1986–1988) (replacing Jack Spector), a five-hour nightly sports call-in show that was a precursor to the all-sports talk format of WFAN.[6] He was hired by Michael Weisman as a reporter covering track and field for NBC Sports' telecast of the 1988 Summer Olympics.[7] He went on to cohost the midday show with Ed ColemanonNew York's Sports Radio 66 WFAN, Sept. 1989-Feb. 1993. He then became a weekend sports anchor at WCBS-TVinNew York (1995–1998) and also was a radio host for the New York Knicks (1986–1993).
Sims' play-by-play announcing career began (1990–1992) as the radio voice of Temple Owls football in the Big East. Moving to TV, Sims was the TV voice of the Big East Conference football game of the week (1993–1994) and then again (1998–2007).
In1991, Sims joined ESPN as a play-by-play announcer for college basketball, and added college footballin1998. He primarily called Big East contests on the ESPN Plus regional network. He continues to broadcast college basketball games for FOX and FS1 beginning in 2016.
Sims was the #2 broadcaster for NFL on Westwood One Sports's Sunday afternoon doubleheader before taking the permanent play-by-play position on Sunday Night Football.[8] He replaced Joel Meyers on the Sunday Night Football game in 2006. Sims worked "Sunday Night Football" games from 2006 to 2012. From 2013 to 2014, Sims returned to Sunday Afternoon NFL action while working with former NFL quarterback Mark Malone.
In addition to Sunday Night Football, Sims also called college basketball for Westwood One (1998–2014) with his most notable call to date being the George Mason-UConn regional final in 2006 (where #11 seed George Mason upset top-seed Connecticut to become the second #11 seed in history to reach the Final Four).
While working in other sports, he occasionally provided Major League Baseball play-by-play for ESPN (1993–1994) and did an internet radio show for MLB.com (1999–2000). In 2007, he took the opportunity to return to baseball full-time as part of the Seattle Mariners television broadcast.[5] One of the few African-American broadcasters in the history of the sport, he is also perhaps the only one of that group not to have played in the major leagues. His broadcast partner is former Mariners 3B Mike Blowers.[5]
Sims was the broadcaster on Fox on April 21, 2012, describing Philip Humber's perfect game.[9] However, the game was broadcast in its entirety only in the Chicago and Seattle markets, because the rest of the country heard Joe Buck and Tim McCarver call a game between the New York Yankees and the Boston Red Sox. Because the game was broadcast on FOX in both markets, Sims had to call the game from a neutral standpoint as a broadcaster and not as the usual Mariners broadcaster, even though his team lost to a perfect game.
Just four months after calling Philip Humber's perfect game, Félix Hernández threw the first perfect game in Mariners' history. Sims called the game for Root Sports in Seattle.[10] This is the first time that one broadcaster has called two perfect games in the same Major League Baseball season.[10]
"Boomstick Baby!"- used whenever Nelson Cruz hit a home run.[11]
"Holy Mackerel"/"How about that?"- used for exciting plays.
”Bro-uh-uh-uh-uh-uh-ther.” - used after a particularly dispiriting loss or play.
”Hey Now!”- used after exciting game changing plays.
” Got him!” After a Mariner pitcher strikes out an opposing batter.
Sims is a staunch believer in letting his audience know when a pitcher is working on a no-hitter. "I have to tell the audience what’s going on…if a guy’s throwing a no-no, I have to report it."[12]
