"Wow," Williams said. "Wrong move, but wow."
Harper's heave encapsulated the 21-year-old's immense ability -- and his tendency to force plays at times, whether it's on the field or on the bases. Williams does want to keep the runner at second base in such a situation, but he also doesn't want to eliminate Harper's aggressiveness at the expense of compromising his talent.
"He comes up, and most guys go, 'Well, there's no chance for me to throw him out at the plate,'" Williams said. "His brain goes, 'Well, I've got a chance.' So that's what young, special talent does. We'll take the good and the bad and move forward into tomorrow and run him out there again."
