Mananchaya Sawangkaew vs Panna Udvardy — R128 — US Open

Ranked 21 places higher and still not the betting market's pick, Udvardy is out of the US Open, her serve holding only five times in nine games. 10Bet had Sawangkaew at 59 percent, and the return games bore that out: she broke back in game 5 for 2-3 and won 45 percent of the points on Udvardy's first serve. Udvardy out-hit her 17 winners to 10 and struck six aces to none, though 33 unforced errors against 22 put the points count 75-65 the wrong way. The win, in 1h 35m, is Sawangkaew's first since the Wimbledon run that ended in the round of 32, and it moves her into the second round in New York.
