Aryna Sabalenka avoids major shock with fightback win over Laura Siegemund

Top seed and title favourite Aryna Sabalenka survived an almighty scare against world number 104 Laura Siegemund before reaching the Wimbledon semi-finals.

Sabalenka, the runaway world number one and a three-time grand slam champion, had not dropped a set on her way to the quarter-finals.

But 37-year-old Siegemund, who had never previously been beyond the second round, almost produced one of the all-time Centre Court shocks after taking the first set and then twice leading by a break in the decider.
