Barton came into spring camp with a new physique. The A's first baseman believes he has added about 15 pounds of muscle while losing 10 pounds of fat, based on his body fat decrease - he's down 4 percent after strenuous workouts this offseason with Southern California trainer Brad Davidson.
The A's, of course, love what Barton does bring, even without large homer totals. He led the league in walks last year, and his defensive work is outstanding.
