Nationals' first basemen could miss rest of season

Nationals first baseman Nick Johnson will undergo surgery Tuesday on his injured right wrist and may not return this season. "We'll know more tomorrow when they operate, but there's a possibility he might be out for the year," Nationals general manager Jim Bowden said before Monday night's game against the Angels. Johnson has been on the disabled list since May 15 with a tear in the tendon sheath of his right wrist. [link]
