Major League Baseball Is Back In Full Swing On XM Satellite Radio

XM to broadcast Major League Baseball games for every team, all season long starting April 2; XM coverage of World Baseball Classic, Spring Training continues this month; Orestes Destrade joins XM’s MLB Home Plate channel

Washington D.C., March 16, 2006 -- Major League Baseball is back in full swing on XM Satellite Radio, the official satellite radio network of MLB.

The 2006 MLB season officially begins with Opening Day on April 2 as the World Series champion Chicago White Sox host the Cleveland Indians at U.S. Cellular Field. Baseball fans across the country can listen to their favorite teams all season long on XM, which airs live play-by-play coverage of games for every MLB team throughout the season.

This month, XM is broadcasting every game of the inaugural World Baseball Classic from cities across the globe, culminating with the WBC championship game on March 20 at PETCO Park in San Diego. XM is also broadcasting select Spring Training match-ups live from Florida and Arizona.

MLB games are carried live on XM channels 176 through 189, with Spanish play-by-play on MLB En Espanol (XM channel 190). Plus, XM is the exclusive home of MLB Home Plate (XM channel 175), the first and only national, year-round talk radio channel devoted solely to baseball. MLB Home Plate has an all-star line-up of on-air talent, including baseball legend Cal Ripken, Jr., who hosts the weekly XM show “Ripken Baseball” with his brother and fellow MLB veteran Bill Ripken. New York Yankees’ All-Star shortstop Derek Jeter recently signed on to make regular guest appearances on MLB Home Plate programs.

The newest member of the MLB Home Plate broadcast team is former major leaguer Orestes Destrade. XM announced today that Destrade will co-host MLB Home Plate’s popular morning program “Baseball This Morning” with Mark Patrick and Buck Martinez. Destrade debuted on XM in 2005 as an on-air host for MLB En Espanol. Destrade recently joined ESPN as an analyst for “Baseball Tonight.”

“Major League Baseball is the premier radio sport, and with XM, you can hear every team, all season long, from Opening Day to the World Series,” said Eric Logan, executive vice president of programming, XM Satellite Radio. “Baseball fans have grown up listening to games on the radio, and now we can hear games from all across the country on XM radios, whether we’re in the car, at home, or at the ballpark. XM started carrying MLB games last year as part of an 11-year agreement, and the popularity of MLB on XM has helped make us the number-one satellite radio company with more than 6 million subscribers.”
