OAKLAND -- Sam Fuld jogs to the outfield each inning with enough gum in his back pocket to give him a quick boost of carbohydrates if his blood sugar dips.
He might experience dizziness or feel weak. That's how he knows.
"It's just a crummy feeling," he said. "You get a little irritable."
After nearly eight years in the majors, Fuld has learned to count his carbs and determine his insulin without nutritional labels on much of the clubhouse food from ballpark to ballpark, city to city.
A Type 1 diabetic, diagnosed at age 10, his body requires constant attention all day long to stay in top form for the Oakland Athletics.
