Courtesy, Buster Olney:
1. He had the Cubs chasing pitches all night; they swung at 23 of 47 pitches outside the strike zone (49 percent, MLB average 25 percent) and 13 of 19 2-strike pitches off the plate (68 percent, MLB average 38 percent).
2. He threw just 3.3 pitches per hitter (average 3.7 pitchers per hitter entering the game).
Or, because he's awesome.
