Monasterios was the Dodgers' losing pitcher Friday night, when he made 72 pitches and allowed six runs in four-plus innings. After the game, he made no mention of an injury, but the club said he had a preexisting blood blister on the middle finger of his pitching hand and a split nail on the index finger that occurred Friday night.
After Friday night's loss, manager Joe Torre implied that Monasterios would probably lose his spot in the rotation and be returned to the bullpen, where he started the season effectively while being used judiciously. He started the season with only two games experience above the Class A level.
As a Rule 5 pick, the Dodgers cannot send Monasterios to the Minor Leagues without risking his loss to another club on waivers. He is 3-2 with a 3.88 ERA.
"He has to doctor it every time he goes out there," Torre said of the blister, which originally cropped up three weeks ago. "We'll take this opportunity to get it solved."
Monasterios allowed one home run when carefully used in 11 relief appearances covering 19 1/3 innings the first two months of this season. But in six starts covering 26 2/3 innings, he's been taken deep seven times, five of them in his past three starts. The eight homers allowed lead the staff.
"We're asking him to do a lot," said Torre. "He hasn't thrown consistently when he wanted to and this [the injury] could have something to do with it. And you come to this park, with the history it has, and you look around and it can be pretty intimidating."
