With the 2017 U.S. Open set to kick off on Monday, Aug. 28, in New York, SI's tennis experts and writers Jon Wertheim, Richard Deitsch, Stanley Kay and Jamie Lisanti discuss this year’s top storylines and predict the winners.
What qualifier or other player do you see being a dark horse this year?
Jon Wertheim: I’m not sure we ever reached any resolution insofar as defining a dark horse. If we’re talking no Big Four men, then Alexander Zverev—mirroring his ranking trajectory—springs to the top. Though he qualifies for the main draw on his own ranking, Nick Kyrgios is a wild card, capable of landing anywhere in the entire orbit of result.
