Ivan Nova's curveball was really working last night. In two strike counts, he threw the pitch ten times, resulting in no hits and five strikeouts. Of those five strikeouts, four came on curveballs located out of the zone. I'd like to think that he was able to set that up by locating his curve in the strike zone throughout the game. If batters were aware that Nova was willing to throw the pitch in the zone, they were probably more likely to hack at it in two strike counts.
The two hits he gave up on curves were both located inside the strike zone: a double by Wieters in the 4th on a 2-1 pitch with the bases empty, and a single by Adam Jones in the 6th on an 0-1 pitch with the bases empty.
The one backwards K Nova recorded with his curveball last night came in the bottom of the seventh against Robert Andino. That must be why he was so testy after the game....
