World number one Novak Djokovic won’t get a better chance to make it 13 Grand Slam wins at this year’s US Open after Andy Murray’s capitulation on Wednesday. However, he’s got to overcome a rejuvenated Gael Monfils first, and then either Nishikori or Wawrinka in the final. Wawrinka is the player Djokovic will want to avoid the most as he’s posed him significant problems in all of their Grand Slams encounters bar one, and the way he has come in under the radar again with no pressure on him suggests he’s primed to make a serious challenge for the title.

At the time of writing the women’s semi-finals were due to take place and I Serena Williams is still on to win her 23rd Grand Slam, but is unlikely to find Pliskova a pushover as her serve is on par with William’s and she leads the tournament and WTA for aces this season. The other semi-final between a resurgent Wozniaki and second seed Kerber had all the hallmarks of a real battle of attrition and it would be an amazing comeback if Wozniaki made the final and won her first Grand Slam.
