BOSTON -- Fans wanting an authentic memento of a David Ortiz season to remember will have another chance.
The Red Sox and the slugger announced on Tuesday that Ortiz's home run ball No. 52 is being auctioned off online through Friday at 7 p.m. ET. Ortiz did the same for homer No. 50. Bidding for that ball ended on Tuesday night.
As was the case previously, the proceeds received from the winning bid will be donated to the Boys & Girls Clubs of America and the Plaza de la Salud Hospital de Niños, which is located in Ortiz's hometown of Santo Domingo, Dominican Republic.
Ortiz belted No. 52 on Sept. 21 against Minnesota, the same night he clouted No. 51 to set the club's new single-season home run mark. Tommy Valieriani, a 10-year-old boy from Boxford, Mass., was the lucky fan to catch the ball. The Red Sox and Ortiz traded several autographed items with Valieriani and Joel McGrath, 29, of Waltham, Mass., the man who hauled in long ball No. 51.
