Alexander Zverev overcame a late wobble to take his place in the last 16 of the Madrid Open.

Zverev had the chance to serve out the match at 5-3 up against Terence Atmane, yet he squandered that opportunity.

Atmane broke back, and then fended off a match point in the next game to restore parity.

Zverev, however, regained his composure, with the second seed winning the tie-break to prevail 6-3 7-6 (7-2).

Earlier on, Flavio Cobolli beat Adolfo Daniel Vallejo to tee up a clash with Daniil Medvedev.

World number five Felix Auger-Aliassime, meanwhile, fell to a shock 7-6 (7-3) 6-3 defeat to Alexander Blockx.
