Ivan Nova hasn't lost a game for the New York Yankees since June 3rd of last season. And while wins and losses are the worst gauges of a pitcher's performance, his streak of 14 wins dating back to June 10th of 2011 is impressive nonetheless.
What's especially impressive has been Nova's performance against left-handed hitters. Since the start of his streak on June 10th, Ivan Nova has held lefties to a .227 batting average and a .285 wOBA, compared to .274 and .324 to righties respectively. He's given up just three HRs to lefties in those 20 games, compared to nine HRs to righties.
Nova has kept the ball away from lefties for the most part and limited the damage. His sinking fastball down and away has likely contributed much to his overall success. While the win streak is bound to end at some point this season, Nova should continue to see good results if he keeps up this pitching pattern.
