SAN FRANCISCO -- Third baseman Hanley Ramirez jammed his right thumb on Tuesday in the third inning of the Dominican Republic's 3-0 win over Puerto Rico in the World Baseball Classic championship game at AT&T Park, said Moises Alou, the club's general manager.
Ramirez left the game in the sixth inning for precautionary reasons and had his thumb placed in a splint. He will undergo further examination on Wednesday, when Ramirez rejoins the Dodgers at their Camelback Ranch training facility in Glendale, Ariz.
"Hanley, he jammed his thumb when he dove for that ball," Alou said after the Dominican Republic ran off eight consecutive wins to go undefeated and win the Classic for the first time. "It was pretty swollen. He's going to have an MRI on it [Wednesday] in Arizona."
Playing on a wet field at AT&T Park, Ramirez injured the thumb while diving to his left for a Jesus Feliciano single in the third inning. He was seen flexing his thumb and throwing hand after the play but remained in the game.
Ramirez singled in his next at-bat, one inning later, but was lifted for Miguel Tejada to start the sixth. Ramirez was 1-for-2 in the game.
Ramirez batted .227 (5-for-22) with two homers and three RBIs as he started all eight of the Dominican Republic's games in the Classic.
