- Australian led semi-final 6-3, 2-6, 4-0 when Draper forced from court
- World No 9 to face Casper Ruud or Holger Rune in final in Acapulco
Defending champion Alex de Minaur has advanced to the final of the Mexican Open after Jack Draper retired in the third set of their last-four clash.
The third-seeded Australian won the first set 6-3, dropped the second 6-2 and was leading 4-0 in the third when Draper, who was visibly diminished physically, called it quits.
