Marcelo Arevalo of El Salvador and Dutchman Matwe Middelkoop battled through a nail-biting Match Tie-break on Sunday evening to defeat South African Raven Klaasen and Japan’s Ben McLachlan 6-2, 0-6, 11-9 in the first round of the BNP Paribas Open.

It will not get easier for the unseeded duo, which will next play top seeds Nikola Mektic and Mate Pavic, who have won nine titles together this year. The Croatians eliminated Americans Mackenzie McDonald and Brandon Nakashima 6-2, 6-2.
