JUPITER, Fla. -- Nationals catcher Alberto Castillo played a role in convincing Alfonso Soriano to play left field on Wednesday afternoon.
The two were on the bus, on their way to Roger Dean Stadium, when Castillo told his teammate that teams will look at him as a versatile player once he becomes a free agent after the season if he played left field for Washington.
Castillo and Soriano have been friends since they were teammates with the Yankees in 2002. They both represented the Dominican Republic in the World Baseball Classic.
"Other clubs will look at him as a second baseman or an outfielder," Castillo said. "Mentally, he is happy. He is going to play [the outfield]. I gave him some sound advice. I told him to go there, have fun. If he misses a fly ball, he has to come back the next day and try to get a coach who can hit him fly balls."
Outfielder Jose Guillen said he expects everybody to be patient with Soriano if he makes mistakes in the outfield.
"Let's not expect him to be the best left fielder in baseball, because everybody knows he doesn't know how to play the position yet," Guillen said. "He is here for his bat, not his defense."
More on Soriano: Manager Frank Robinson said that if Jose Vidro were to get hurt and miss a few games, Soriano would not get the start at second base. Infielder Damian Jackson most likely would get the nod. Robinson does not want Soriano to go back and forth between the outfield and second base.
Learning the ropes: Third baseman Ryan Zimmerman has been voted the alternate player representative regarding union matters. Catcher Brian Schneider encouraged Zimmerman, 21, to get involved and learn the system.
"It was up to the older guys," Zimmerman said. "I guess they figured I will be in the game for a long time, so they figure I might as well learn what goes on. It will be a good learning experience."
