Daily Data Viz: Stan Wawrinka vs. Donald Young head to head

Monday September 7th, 2015

No. 5 Stan Wawrinka and Donald Young face off in the fourth round on Monday for a spot in the quarterfinals. So far at the U.S. Open, Wawrinka's serve has been solid—44 aces; 76% won on first serves; 55% won on second serve. He's hit a total of 57 forehand winners and 33 backhand winners, but his return game has not been strong, with 43% won on returning second serves. For Young, his serve has been a problem. He faced 57 break points in three rounds and has been broken 22 times. He's hit 59 forehand winners, but more total unforced errors than winners and return of serve has been his strength, especially against second serves. He has broken serve 23 times in three matches.

But how do they match up head-to-head? They have split their previous two meetings—both four years ago on hard courts. Wawrinka has the big edge on serve, but his first serve percentage (just 53% in play) could hurt him as Young has excelled when returning second serves (59% won). Young has come back from losing the first set in all three of his matches here while Wawrinka hasn't dropped a set. Young has put in more than two hours more on court and has run more than two miles farther than Wawrinka to reach this match.

Wawrinka is a strong front runner and losing the first two sets as Young has done in two of his three victories isn't a great strategy against the Swiss. The key for Young will be to get his service game going early. He's only served well once he's been behind, he'll need to stay with Stan early in the match to make him feel the pressure. Since they last played, Wawrinka has won two Grand Slam singles titles and improved his ranking from 19 to 5 and Young's ranking has dropped from 44 to 68.
