It was the new kid on the block against the experienced head as Karen Khachanov and Marcos Bagdhatis played out a thriller on Court 18. Bagdhatis was a semi-finalist here 12 years ago and he nearly got the better of the 22-year-old Russian, coming from two sets down to force a decider. However, Khachanov eventually won 6-3 6-4 3-6 6-7 (4/7) 7-5.

A good day for…

A year on from suffering a sickening knee injury, which kept her out for almost a year, Bethanie Mattek-Sands was back on the Wimbledon match court. The American was able to exorcise her demons as she again paired up with Lucie Safarova in the women’s doubles and triumphed 7-6 (8/6) 7-5 against Lyudmyla Kichenok and Alla Kudryavtseva.

A bad day for…

Marin Cilic may well curse the British weather for as long as he lives. The Croatian, a fancied tip for the title, was two sets up against Guido Pella on Wednesday when – in the midst of a heatwave – rain ended the day’s play. The pair came back on Thursday and Cilic found himself up against an inspired Argentinian, who came back to win 3-6 1-6 6-4 7-6 (7/3) 7-5.

Quote of the day

“Because you generally talk to someone when you’re curious about something. Doesn’t make you upset, champ. Good question.” – Nick Kyrgios was happy to give a journalist some feedback on his questioning after being asked why he spoke to the umpire about a code violation in his straight-sets win over Robin Hasse.

Stat of the day

John Isner served himself into third position in a list he is also already top of. In his five-set thriller against Ruben Bemelmans, which he prevailed 6-1 6-4 6-7 (6/8) 6-7 (3/7) 7-5, the American sent down 64 aces. That tally has only been beaten in a Wimbledon match by Isner and Nicolas Mahut in their record-breaking marathon match in 2010.

Sam Querrey is back on Centre Court after his run to the semi-final last year and an intriguing match-up with Gael Monfils awaits. Querrey is a big-server, who deals in aces, while Monfils is the top entertainer on the tour. However, the Frenchman has to show he has the desire as well, with his compatriot Marion Bartoli suggesting he does not work hard enough to win a grand slam.
