Hello! A brilliant backhand pass gives Sandgren a break! As I said, he’d be as well to tank Fognini’s service games, and he’ll now serve for the second set. 7.55am GMT
This is a really good match now; Fognini is steaming hot. If I were Sandgren, I’d think about taking his service games off now, to recuperate for a breaker. Five games on the spin for Fognini, who leads 5-4 in the second; Sandgren by one set to love.
