Second seed and defending champion Zverev also has a tricky first-round opponent in the form of American Jenson Brooksby.

Zverev's projected quarter-final opponent, Cameron Norrie, finds himself in a similarly precarious spot, locked in a first-round tussle against Carlos Alcaraz.

Tsitsipas and Pablo Carreno Busta, the other seeds in the bottom half, have relatively simple paths leading up to the last eight.

Schedule
The Mexican Open will take place between February 21-26, with the draw featuring 32 players.
