Now those questions seem to have vanished. Bell, 23, has slimmed down considerably from his listed 6-foot-3, 235 pounds and become a more reliable defender at third base, even winning the Best Defensive Third Baseman honor from Double-A Southern League managers in Baseball America’s Best Tools survey. He’s always had an above-average arm, but those who have followed Bell this season say his actions look cleaner and his improved conditioning has helped his range.
