The win gives the 37-year-old his first main draw victory since the 2018 US Open. He has primarily competed on the ATP Challenger Tour over the past six months, but qualified for the main draw this year at ATP Tour events in Doha and Cordoba.

Next up for Lorenzi is the winner between Ryan Harrison of the United States and Peter Polansky of Canada.

Bernard Tomic also picked up his first ATP Tour main draw win of 2019 with a convincing 6-4, 6-2 victory over Lukas Lacko in just 53 minutes. The Aussie will next face top seed John Isner.

Joining Tomic in the second round is fellow Aussie and No. 7 seed Jordan Thompson, who won nine of the final 10 games to defeat American wild card and New York native Noah Rubin 6-7(7) 7-5, 6-1. Thompson squandered eight set points in the first set, including five in the tie-break, and was forced to serve to stay in the match at 4-5 in the second set. After securing his first break of the match at 5-5-5 in the second set, he finished strongly to prevail in two hours and 35 minutes.

"I think a lot of guys could have gone away if they were in my position after that first set," said Thompson. "I competed hard, hung tough and scraped out a win."

Thompson will now play the winner of the all-qualifier battle between American Christopher Eubanks and Spaniard Adrian Menendez-Maceiras.
