Greek sensation Stefanos Tsitsipas showed flexibility and maturity on Tuesday to reach his first Grand Slam semi-final with a 7-5, 4-6, 6-4, 7-6 (7/2) win over Roberto Bautista Agut.

Stefanos Tsitsipas had to contend with dropping his serve early in each of the first three sets to the Spanish 22nd seed before coming through in 3hr 15min.

The 14th seed will face either world number two Rafael Nadal or unseeded Frances Tiafoe in the last four.
