Aryna Sabalenka displayed frustration and anguish but battled back from a set down to reach the Wimbledon semi-finals. The world No1 appeared close to crashing out of the Championships at multiple occasions at the hands of the unseeded 37-year-old Laura Siegemund but won 4-6 6-2 6-4 in a fraught encounter on Centre Court.

The world No. 1 was thrown off by Siegemund's changes in pace and rhythm, but came through in three tight, tense sets.

Aryna Sabalenka completed a hard-fought comeback against Laura Siegmund to avoid elimination and move on to the semifinals at Wimbledon. The pair met at center court on Tuesday morning as Siegmund looked for another upset win after eliminating Madison Keys in the third round.
