These two have quite a history, encompassing nine matches. Del Potro won the last one, at Wimbledon in 2013. Ferrer is 34 years old and still a handful.No. 1 Serena Williams versus?Johanna Larsson, not before 1 p.m. ET on Arthur Ashe Stadium (Watch)Worries about the sore right shoulder that forced Serena to withdraw from Cincinnati seem to have vanished. She isnt hitting the ball as cleanly as she would like, but shes been composed, which will help her going forward. Williams is 2-0 head-to-head against the Swedish player.No. 2 Andy Murray versus Paolo Lorenzi, after Serena-Larson (Watch)Murray has looked like the favorite so far, averaging better than 6-3 for each of his six sets. The two have played only once, and it was 10 years ago in Adelaide, Australia. Murray won in three sets.No. 21?Ivo Karlovic versus James Donaldson, fourth match on Court 17 (Watch)??The 19-year-old American has defied gravity so far, and now he has a chance to reach the second week here. Hell have to get past Karlovic, who stroked a US Open-record 61 aces in his first-round match and 24 more in the second.No. 6 Venus Williams versus No. 26 Laura Siegemund, 7 p.m. ET on Arthur Ashe Stadium (Watch)This might be tougher than it looks.

Siegemund reached the quarterfinals of the Olympics, losing to eventual gold medalist Monic Puig.No. 14 Nick Kyrgios versus Illya Marchenko, after Venus- Siegemund (Watch)Kyrgios, the brash 21-year-old Aussie, has been making waves again this fortnight.
