The racket then bounced up and slammed into the umpire's chair, yet Gavrilova escaped punishment and went on to win the match 4-6 6-3 6-3.
Gavrilova lost her temper during a tennis match against American Madison Brengle at the Acapulco Open on Monday, the Australian throwing her racket after misfiring on a serve and almost hitting a ballkid. The second set, Tsurenko was formed easier - Lesya again won three consecutive games and finished the match in their favor.
Lesia Tsurenko made a winning start to her title defence at the Abierto Mexicano Telcel, while third seed Daria Gavrilova was also victorious on day one.
But Davis was no match for Ukraine's Tsurenko, who will meet Australian Arina Rodionova after Kateryna Kozlova was forced to retire from the match trailing 6-2 1-0.
"It was so hot, especially in the first set, but I looked at the weather forecast and so I knew it that after an hour or so the weather would drop down", Gavrilova said.
On the men's side of the joint WTA and ATP tournament, David Ferrer of Spain breezed past Russia's Andrey Rublev 6-4, 6-3 in a night match to reach the second round.

She faces a second-round match with Paraguay's Veronica Cepede Royg after she defeated Switzerland's Belinda Bencic 4-6, 7-6 (1), 6-3.
