X-rays taken of Will Clark's injured ankle Saturday were negative, but the San Francisco Giants first baseman was held out of an exhibition game against the Oakland Athletics as a precautionary measure.

Clark sprained his right ankle during a workout Friday night before the opening game of a three-game series against the A's. Clark had two singles and a double in three at-bats before being removed in the sixth inning.Giants manager Roger Craig said Clark was not likely to start in the series' finale Sunday, but would play part of that game.
