The 5th Day of the US Open is highlighted by a fantastic All-American matchup in the 3rd Round of the Women's tournament as No. 15 seed Sloane Stephens takes on No. 23 seed Jamie Hampton.
Stephens was fantastic in her second round win over Urszula Radwanska and appears primed for a showdown with Serena Williams later in the tournament. Hampton has won both of her matches in Flushing in straight sets. Which American will move on to the Round of 16? Here are two other matches to keep an eye on during Day 5:
Juan Martin Del Potro vs. Lleyton Hewitt - A matchup of two former US Open Champions, the Argentine had an excellent Wimbledon taking Novak Djokovic to the max in a classic Wimbledon semifinal. Oddsmakers expect Del Potro to make a real run this tournament. However, the veteran Hewitt stands in Del Potro's way. Hewitt has beaten Del Potro the last two times the players met; both in 2013. Can Hewitt pull the upset for the third time this year?
Na Li vs. Laura Robson - A rematch from last year's Round of 32, China's No. 1 Na Li takes on Great Britain's top female player Laura Robson. Last year, Robson earned the upset in 3 sets. Na Li has had a good summer making 2 semifinal appearances in tune up tournaments. Can Robson repeat the magic of 2012 and make a career defining run? Or will Na Li exact revenge of last year's loss?
