Garin puts on a show at his hometown Chile Open, Berrettini brothers advance in Acapulco
Cristian Garin enjoyed the hometown advantage during Tuesday's opening round of the Chile Open, defeating former world number three Dominic Thiem 6-2 7-6 (7-2).
Slotted into the primetime fixture, Santiago resident Garin did not let the locals down, securing a break in the first game of the match to set the tone.
The other Chilean hopeful in the field, Nicolas Jarry, kept up his terrific form to also book his place in the second round.
After making the semi-final of last week's Rio Open – where he took a set off world number two Carlos Alcaraz – Jarry beat Peru's Juan Pablo Varillas 7-6 (7-1) 6-4 for an 11th victory from his past 14 matches.
Fifth seed Albert Ramos-Vinolas was the highest-ranked player in action, and he went down 7-5 4-6 7-5 against Brazil's Thiago Monteiro, while sixth seed Laslo Djere had a better outing in his 6-3 6-2 victory over Joao Sousa.
Tomas Martin Etcheverry will meet second seed Francisco Cerundolo in an all-Argentine second round matchup after advancing past Italy's Fabio Fognini 6-1 7-6 (7-1).
Meanwhile, in Acapulco at the Mexican Open it was the Berrettini brothers stealing the headlines on a day where top hopes Alcaraz and Cameron Norrie both withdrew due to injuries.
World number 24 Matteo Berrettini won the first seven games of his match against Alex Molcan before the Slovak decided to retire at 6-0 1-0, and his younger brother Jacopo Berrettini capitalised on his qualifier status with a 3-6 7-6 (7-3) 2-1 (retired) comeback against Oscar Otte.
Australian eighth seed Alex De Minaur was the top seed in action and he discarded of Mexico's own 17-year-old qualifier Rodrigo Pacheco Mendez 6-1 6-2, while rising 21-year-old American Brandon Nakashima overcame Germany's Daniel Altmaier 6-3 3-6 6-1.
