In a quarter-final line-up where three of the four matches featured first-time meetings, the opening match pitted last year’s defeated finalist, Denmark’s towering Clara Tauson, against fourth seed Jessica Pegula.

Prior to play, neither player had lost a set in Dubai this year and the early throes of the tie demonstrated exactly why, as both exchanged blistering baseline groundstroke winners under the early afternoon sunshine. After a tense 40-plus minutes, a single break of serve was enough for Pegula to take the first set, 6-3.

The second set, however, saw a sharp reversal of fortunes. Tauson, widely regarded as a junior prodigy after surpassing 2011 Dubai champion’s Caroline Wozniacki record as the youngest winner of the Danish tennis championship before she became the first Dane to top the junior world rankings, rediscovered her ruthless streak.
