Washington's Nick Johnson has been discussed as a potential trade candidate internally by the San Francisco Giants. Johnson might be off the market after winning the everyday first-base job and starting the season strongly.

A source said the Giants scouted 26-year-old Braves first baseman Scott Thorman.

In spring training, the A's attempted to ship Dan Johnson to the Giants.
