This is definitely one to tell the grandkids about. Better yet, you can show them Mark Prior's masterful domination of the Atlanta Braves in Game 3 of the National League Division Series.

Prior was simply sensational as he shut down the Braves, 3-1, in a complete-game, two-hitter at Wrigley Field on Friday. He started shaky, walking two batters in the first inning, but never looked back after that, striking out seven hitters in the win.

Cubs fans, this is your chance to own this historic playoff moment.

You can order the game right now for only $3.95 and then download it 24 hours after the final pitch. File sizes range between 400-600MB, and you then can burn them onto a CD for optional storing and then start your own personal video library -- right through the final World Series moment. It's a piece of memorabilia that will come in handy on everything from airline trips to lunch breaks to those lonely offseason nights.

After the most spectacular pennant-race drama of any Major League regular season, this promises to be a postseason that you will want to keep for posterity. Individually, it is loaded with future Hall of Famers such as Barry Bonds, Roger Clemens and Sammy Sosa. There are seven clubs in the field (also the 1993-circa Marlins) that existed when the World Series began 100 years ago, and that includes the franchises that rank 1-2 in Fall Classic victories (the Yankees with 26 and the A's with nine -- matching the Cardinals). It also includes the Cubs and Red Sox, clubs that are a combined 180 years removed from that last world title and playing in the two oldest parks.

If you are one of those lifelong Cubs fans who are not about to take a postseason opportunity for granted, then the Digital Download Service allows you to hold onto every game no matter how far Kerry Wood and his teammates go. Not only can you download his pitch-and-hit masterpiece to beat Atlanta in Game 1 Tuesday, but you also can download his best career game ever -- the 20-strikeout masterpiece when he was a rookie in 1998.

There are no commercials in these downloads, so a typical game should last about two hours. The RealVideo file will take approximately 40 minutes to download from a broadband connection (DSL may take longer).

You've experienced MP3 players. This is the baseball version, an MVP, as in must-view pastime player. Be the first on your block or at the office to download one.

No one could imagine having this personal capability when Kirk Gibson limped up to the plate in the 1988 World Series and hit a miracle pinch-homer off Dennis Eckersley, of course, but the Digital Download Service now even lets you own a moment like that. MLB.com's exclusive Baseball's Best library now is making many of its classic broadcasts available for you to download.

Own that 1975 World Series Game 6 and relive all of that drama, from Bernie Carbo's pinch-homer to Carlton Fisk's 12th-inning homer. Never search again for that highlight of Luis Gonzalez's hit off Mariano Rivera to give Arizona its first world championship in 2001. Yankee fans might prefer to download Game 4 of that series, when Derek Jeter became the first Mr. November. That is the "Feature Download" today at the Digital Download Service, and you can keep checking to see which new ones are added in the future.

If you are a Yankees fan, then that Jeter download could be the beginning to your own personal video library. You also can download: any 2003 postseason game they play; the 1978 one-game playoff in which Bucky Dent beat the Red Sox; and Clemens' 300th win and 4,000th strikeout on June 13.

That last download is one of several that were available during the regular season, when this revolutionary service was launched. Others available for download from 2003 were: Kevin Millwood's no-hitter for Philadelphia on April 27; Houston's six-pitcher no-hitter June 11 at Yankee Stadium; and the Cubs' NL Central clincher and celebration on Sept. 27 at Wrigley Field.

The Digital Download Service is one of the many exclusive video products and services available at MLB.com through this postseason. Visit MLB.com's Video Central for a menu of choices, and get access to even more exclusive products with subscription packages such as Total Ticket, Fantasy Ticket and MLB.com Broadband.
