INDIANAPOLIS -- Cristian Guzman still isn't sure if he's on board with making the switch from shortstop to second base for the Nationals, according to his agent, Stanley King, and there are no plans for him to play winter ball in order to get acclimated at the new position, which he has never played.

At the moment, Guzman is still recovering from right shoulder surgery, which took place in early October.

"I'm really not certain. I know that he still feels he is a good, viable shortstop," King said recently. "I know he will do anything and everything possible to help the Nationals win. Once he had his surgery, our conversations have shifted to him getting healthy.

"Right now there aren't any plans [to play winter ball]. Our first concern is to make certain his arm is 100 percent and he is doing all of his therapy, which he is doing now."

The Nationals informed Guzman of their plans last September and he was in shock. The Nationals believe he has a tough time going to his left while playing shortstop.

This is not the first time Guzman has been asked to make a position switch. In the 2008 All-Star Game, he was excited by the fact that he played errorless ball for six innings at third base.

Then-Rockies manager Clint Hurdle put Guzman at third because he didn't want to take Astros shortstop Miguel Tejada out of the game. Plus, Mets third baseman David Wright was the designated hitter, and Hurdle was running out of players.

Guzman admitted back then he was nervous about playing the position.

"In the first inning, I was so nervous," Guzman said in July of 2008. "I never played third in my life. We didn't have any more infielders. [Hurdle] talked to me and he asked, 'Are you going to play third?' I go, 'Why not?'
