Carpenter called it a, "freak accident,"
The bat shattered as he drove a single to left field with one out in the third. The remains of the bat cut into his hands as he left go. He remained on base during the first three pitches to the next batter, Matt Holliday, but called time to have the training staff come out and look at his hands, which were bleeding profusely at that point.
"Blood was coming down all over my pants," he said. "It was weird."
Carpenter said he got a piece of skin glued back into place, but he did not need stitches. He is considered day to day according to manager Mike Matheny.
"I've never seen anything like that," Matheny said. "The bat flew out of his hand and it started bleeding pretty good."
Adron Chambers replaced Carpenter at first base and stayed in the game to play right field.
Carpenter came into the contest hitting .299 with four homers and 40 RBIs. He went 2-for-4 on Friday in a 5-4 loss to Milwaukee in 13 innings.
"I've broken a million bats and nothing like that has ever happened," Carpenter said.
