Still sick with a stomach flu that cut short his opening-day start, Clayton Kershaw said he was "pretty sure" he would be able to pitch in the Dodgers' home opener Tuesday.

"We'll see," Kershaw said.

Kershaw reported a minor improvement in his condition.

He pitched three scoreless innings Thursday in the Dodgers' 5-3 victory over the San Diego Padres.

"I felt pretty bad," he said. "I know I needed to try to get out there. After that third inning, I started getting dizzy and lightheaded and stuff, so I really couldn't do it anymore."

Upon exiting the game, Kershaw tried to return to the team hotel across the street from Petco Park but was too weak to do so.

He said he threw up in the eighth inning.
