Dodgers uncertain if Carlos Frias can make next start

The Dodgers are uncertain if Carlos Frias will make his scheduled start Monday against the Philadelphia Phillies since the rookie right-hander is dealing with lower back problems that limited him in his last appearance.

“He was OK today,” Manager Don Mattingly said. “I don’t think quite as good as we’d like him to be, so I think we’re still kind of talking about that. We haven’t really made a decision on that yet.”

Frias was able to throw a bullpen session, but Mattingly said the discomfort “wasn’t like free and just totally out of his mind.”

Frias underwent an MRI examination that revealed no structural problems with his back.

“That doesn’t mean he’s not still feeling some pain,” Mattingly said.

Frias pitched five innings in his most recent start, which was against the Arizona Diamondbacks on Tuesday.

Frias has pitched in 14 games for the Dodgers this season, including 12 starts. He is 5-5 with a 4.94 earned-run average.
