Washington Nationals Broadcasters

Charlie Slowes, Radio Play-by-Play

Charlie Slowes has been behind the microphone for every season of Nationals baseball, from the call of the first pitch in club history April 4, 2005 through Daniel Hudson’s historic strikeout of Michael Brantley to end Game 7 of the World Series last October 30th as the Nationals won their first-ever World Championship. That moment sits atop Slowes’ Nationals highlights, a list that includes Jayson Werth’s memorable walk-off home run in Game 4 of the 2012 National League Division series, Max Scherzer’s 20-strikeout game, three no-hitters in just over a calendar year—thrown by Jordan Zimmermann (Sept. 28, 2014) and Scherzer (June 20 & Oct. 3, 2015), Bryce Harper’s three-homer game in 2015, the Nats’ four consecutive home runs in San Diego June 9th, 2019 and Kurt Suzuki’s walk-off, three-run homer that capped a 7-run bottom of the 9th inning to beat the Mets last September 3rd. Slowes’ call “and if you walked out of this ball park when the Mets scored five runs in the top of the 9th inning, you BLEW IT!” with partner Dave Jageler, became a tv/radio/internet/social media phenomenon shortly thereafter.

Slowes became the original voice of the Nationals on February 24, 2005, in time for their inaugural spring training. His trademark taglines—“BANG, ZOOM go the fireworks!” and “A #CurlyW is in the books!”—after Nationals victories soon became part of the Beltway baseball lexicon. The 2020 season marks Slowes’ 16th with the Nationals, his 23rd consecutive year calling Major League Baseball, and 28th overall. He will call his 2,500th Nationals broadcast in 2020, entering the campaign having called 3,626 Major League regular season and Postseason games, including 2,463 with the Nationals. Baseball’s return to our nation’s capital in 2005 also marked a return for Slowes, named the radio voice of the NBA’s Washington Bullets in 1986 at just 25 years of age. Slowes called Bullets games through the 1996-97 season, covering 11 seasons, including two years of radio/TV simulcasts. Slowes made the switch to Major League Baseball full-time in 1998 as an original radio voice of the Tampa Bay Rays, calling their first seven seasons. Slowes had previously called games for the New York Mets (1988 & 1991) on WFAN-AM, the Baltimore Orioles (1989-90) on WBAL-AM, and on the network level for NBC-TV and CBS Radio. Slowes also called Triple-A baseball for the Tidewater Tides on radio and TV in 1986, 1988, 1991 and 1992. Slowes is among those (starting with legendary Ford Frick Award-winner and Hall of Famer Vin Scully) to have entered sports broadcasting after graduating from Fordham University in his native New York City, and having honed his skills on Fordham’s 50,000-watt blowtorch, WFUV 90.7 FM. Slowes’ first career break came not long after graduation, in the spring of 1984 at KMOX Radio in St. Louis, where for three years he was exposed to the likes of Ford Frick Award-winners, the late Jack Buck, and Bob Costas. In three years in St. Louis, Slowes was involved in broadcasts of Cardinals baseball, Cardinals football, Blues hockey and play-by-play of St. Louis University basketball. In three-plus decades as a play-by-play broadcaster, Slowes has also called boxing for ESPN, MISL soccer for the New York Arrows (1983) and college basketball at the University of South Florida. During the Nationals’ 2012 NL East Division Championship chase, Slowes joined MLB Network’s afternoon show, “The Rundown,” and will again report for the TV network in 2020. Slowes called play-by-play for his third Washington pro sports team when he filled in for John Walton on Washington Capitals radio during the Caps run to their first Stanley Cup Championship in February of 2018. Charlie and his wife, Tina, have two adult sons, James and Alex, and the family splits time between homes in Alexandria, Virgina, and Palm Harbor, Florida.

Jageler joined the Nationals after spending the 2005 campaign as the radio and TV voice of the Pawtucket Red Sox of the Triple-A International League. Prior to joining Pawtucket, he worked in Boston co-hosting an afternoon talk show and serving in various capacities with the Boston Celtics radio network, including fill-in play-by-play.
