Clayton Kershaw walked into the Dodgers clubhouse at Petco Park on Saturday doing something he hasn't done since the regular season started.

He smiled.

"Better," he said.

Later, Kershaw threw a bullpen session. Pitching coach Rick Honeycutt said that based on what he saw, he felt comfortable sending Kershaw to face the Pittsburgh Pirates on Tuesday in the Dodgers' home opener.

"He's smiling, he's actually walking," Manager Don Mattingly said, referring to how he found Kershaw lying down in the tunnel between the dugout and the clubhouse Thursday.
