One of the Ks was actually a walk. In fact, the pitch wasn't even close...
From where I was sitting, it was close enough to swing with two strikes. (If you were watching on tv you may have had a better view.)
What I really hate (and it isn't just Harper - Werth is notorious, and Zimmerman and Desmond do it too) with a 3-2 count and a close pitch that could go either way, the batter immediately tosses the bat and heads for first, in effect saying, I am reserving the right to be pissed off if you dare call that a strike. And more often than not, the umpire calls a strike, with the batter a third of the way to first, when about half of those times it might have been called a ball if the batter had waited for the call. And of course, Harper got angry, and pouted all the way to the dugout.
