Through 18 games, the Phillies have been just about the team we expected them to be. While Ken Giles hasn't looked like the pitcher we might have expected him to be, it's too early to be concerned.
Ken Giles has thrown 138 pitches thus far in 2015 (entering play on Sunday). It's still early enough that some quick "add that, carry the one, plus that" type of math can figure that number out.
Through eight appearances, Giles has not allowed an earned run, and his six unearned runs, quite frankly, are mostly due in part to a mistake by Odubel Herrera in center field last Wednesday night.
