And we have a tiebreak! Sloane Stephens makes an unforced error to send the match to a decider. Keys was the slightly better player in the final two sets but it’s Stephens who takes the tiebreaker 9-7. Stephens barely celebrates in deference to the feelings of her close friend Keys. But it’s a very welcome result for the 2017 champion, suggesting her struggles with her form may be coming to an end.
Just to give Murray some comfort, there are a few players older than him competing today. 39-year-old Feliciano Lopez has taken Bernabe Zapata Miralles to a fifth set while Ivo Karlovic (42!) lost the first set to Andrey Rublev and is in a tiebreak in the second.
Elsewhere, Murray’s compatriot, Dan Evans, has just won the third set against Brazil’s Thiago Monteiro and leads 2-1.
