World number one Carlos Alcaraz fended off in-form American Tommy Paul 7–6(6), 6–7(0), 6–3 to reach the Cincinnati Open quarter-finals on Thursday, August 17, as other top seeds Daniil Medvedev and Greek Stefanos Tsitsipas were sent packing.
Alcaraz had not looked like himself in an uneven third round performance on Tuesday but was firing on all cylinders on Thursday as he harnessed his mighty forehand to chip away at Paul’s defences in the rain-interrupted battle.
