Kershaw's workout was witnessed by manager Don Mattingly, team surgeon Dr. Neal ElAttrache and head trainer Stan Conte. Kershaw's fastball topped out at 90 mph.
"Obviously, good," said Mattingly. "It sounded like he could do whatever today. We'll see how he comes out of it tomorrow." Mattingly again declined to offer a target date for Kershaw's return, or even the rehab assignment. But taking Sunday as a game day, Kershaw would be in line for a bullpen session on Tuesday and a start on Friday. That would make a following start on April 30 in either the Minor Leagues or Major Leagues.
"We need him to be healthy and compete," Mattingly said. "It's not about going seven innings. If he throws four innings, we've got to cover five with the bullpen. I think we want him built up to the point to compete."
A.J. Ellis, who caught Kershaw 12 days after undergoing knee surgery, said the National League Cy Young Award winner threw all of his pitches and took the workout so seriously that he shook off his catcher.
"He wanted it to be as game-like as possible, and he's always second-guessing me," Ellis joked. "He looked great. He warmed up comparable to a regular start. Velocity was very comparable."
Kershaw said he assumes a Minor League start is next, as long as he comes out of this with no setback.
"This was full-effort for me," he said. "You can't simulate the adrenaline of a big league game. But as far as 10 a.m. sim game, that's all I got."
Kershaw said the soreness and stiffness from the teres major muscle strain in his back that put him on the disabled list after his Opening Night start in Australia "is gone, and now it's just building back up" arm strength.
"He threw the ball real good," said Figgins. "His fastball had life and his curveball was sharp. He threw me a good backdoor slider and threw Butera some changeups. It looked like everything was coming out good."
