What started as a welcoming party for the current top prospect in baseball ended as a celebration of the top player in the game today.

Bryce Harper, the 19-year-old outfielder, collected his first hit in his major league debut with the Washington Nationals on Saturday night. He drove in his first run on a ninth-inning sacrifice fly that ended a tie.

But this game belonged to Matt Kemp, who drove a fastball by Tom Gorzelanny high over the center-field wall in the 10th inning, lifting the Dodgers to a 4-3 victory over the Nationals.

The 54,242 fans who were drawn to Dodger Stadium by the promise of Harper, bobblehead dolls and visiting pitcher Stephen Strasburg stood on their feet and cheered: "M-V-P! M-V-P!"
