Red Sox slugger David Ortiz has autographed this World Series baseball, from the historic 2004 Sox World Series season!

The ball comes with a certificate of authenticity.

As the designated hitter for the Red Sox, David "Big Papi" Ortiz has batted his way into the team's and fans' hearts with his even-tempered attitude and incredible hitting statistics.

In the 2004 season, the ALCS MVP batted .301 with 41 homers and 139 RBI. But perhaps his greatest moments were the multiple game-winning blasts in the postseason, which propelled the BoSox to their first championship since 1918.

In 2006, Ortiz smashed a Red Sox franchise-record 54 home runs!
