"Free-agent left-hander Randy Johnson remains undecided about whether he will return for a 23rd season in 2010.

Johnson's agent, Barry Meister, said that he had dinner with Johnson in Chicago over the weekend, and that the pitcher is still not sure about his immediate plans.

"We talked about whether he wants to play or not," Meister said. "He's still in the process of evaluating all of his options and thinking through it.

"He has played a long time. If anyone has the right to really think it through and figure out what he wants to do, he's the guy."

Meister said Johnson has not set a timetable for his decision.

Johnson, 46, spent last season with the Giants, and threw only 4 1/3 innings after July 5 due to a strained left shoulder."
