He is the second consecutive member of the Red Sox to win the award, given annually to the Major League Baseball player "who best represents the game of baseball through positive contributions on and off the field."
Red Sox pitcher Tim Wakefield won the award last year. It is presented annually at the World Series.
“David’s remarkable commitment to helping children receive essential pediatric care in the United States and the Dominican Republic makes him a wonderful choice for this honor. The legacy of the great Roberto Clemente lives on through the selfless actions of players like David and so many of his peers," baseball commissioner Bud Selig said via an MLB press release.
Ortiz's charitable work includes the David Ortiz Children's Fund, which provides medical care for children in the Dominican Republic and the United States, and a partnership with Massachusetts General Hospital.
“I am incredibly honored to be the recipient of this year's award,” Ortiz said. “It's humbling to be associated with all the tremendous names that have won this award in the past, and I look forward to continuing to do my part to maintain Roberto Clemente's legacy.”
