Clayton Kershaw didn't quite look or sound like himself Friday, roughly 24 hours after leaving his opening-day start early with the stomach flu. He still hadn't eaten and wasn't getting dressed to stretch with his teammates prior to the Dodgers' game against the San Diego Padres.

Still, Kershaw said he was feeling better, which helped ease concerns about his ability to make his next start in Tuesday's home opener against the Pittsburgh Pirates.

"We'll see," he said. "I'm pretty sure."

Most pitchers have a bullpen session two or three days before their upcoming start, but Dodgers manager Don Mattingly said that won't be the benchmark for whether Kershaw will pitch Tuesday.

"He just needs to feel better," Mattingly said. "He's ready. We've got to get him feeling better, where he's hydrated and all that."

Andre Ethier recently had a bout with a stomach bug, so there could be something going around the clubhouse. It seems to be a short-term ailment - good news for the team and for fans who paid good money to see Kershaw pitch opening day.

"Obviously if something would happen where this thing would linger three or four days and he couldn't get on the field, can't throw, can't do anything, and his strength is still not close, then we would have to make an adjustment," Mattingly said.
