I have been watching the Sox play in Yankee Stadium for eons, and I can't remember ever seeing them crush so many balls deep into the left field stands like this.
As far as pitch counts are concerned, it seems to me that a par score for a starter would be 15 pitches. Anything less than that and you're doing very well.
Frankly a Nava type doesn't come along that often, not just for the Sox but for any team. Last year we had guys predicting he'd be pumping gas by now and suggesting the Sox trade him while he had a bit of value.
