BOTH the ATP and WTA Tour took to the court in Mexico for the Abierto Mexicano, effectively the Mexican Open. On the first day of main draw competition, third seed Stan Wawrinka survived a three-set thriller against Frances Tiafoe, while both the second and third seeds in the women’s event dropped out.

The ATP500 event had plenty of big names sign up for the tournament, and the biggest on Day 1 was the Swiss star Wawrinka. Anyone who headed onto the main court at Acapulco was not to be disappointed with Wawrinka and 82nd ranked Tiafoe, with the American having slipped outside the top 50 after poor form this year. He reminded the crowd of what he is capable of though, pushing the world number 16 all the way to a third set tiebreaker, having won the second one in a similar way. However this time it would be Wawrinka – who put down a casual 35 aces on his way to only dropping five first serve points and saving all nine break point opportunities – who would get up, winning 7-1 in the deciding tiebreak to claim victory 6-3 6-7 7-6.

In other results, Miomir Kecmanovic defeated Australian youngster Alex de Minaur who was returning from injury, 3-6 6-4 6-3, while Kyle Edmund toppled experienced Spaniard, Feliciano Lopez. A couple of American qualifiers made it through to the Round of 16 with Tommy Paul knocking off compatriot, Mackenzie McDonald 6-7 6-4 6-4 in a thriller, while Marcos Giron downed Mexican wildcard, Gerardo Lopez Villasenor 6-4 7-6. Rounding out the first day results, France’s Adrian Mannarino finally won his second match for the year after losing six of his past seven, defeating British wildcard Cameron Norrie 2-6 6-3 6-3.
