British No. 3 Cameron Norrie beat Jose Hernandez-Fernandez of the Dominican Republic 7-6 (5), 6-1 in the first round of the Lyon Open in France.
Norrie, ranked No. 102 in the world, had opened up a 3-1 lead in the first set following an early break, but failed to hold onto his own serve in the seventh game as Hernandez-Fernandez rallied.
Both players continued to struggle on serve in the tie-break, with Norrie pushing ahead 4-1 only to then see his opponent edge ahead 5-4.
Norrie, though, then converted two mini-breaks to finally wrap up the opening set, which lasted one hour and seven minutes.
The 21-year-old, born in Johannesburg, South Africa, then raced through the second set in just over 30 minutes.
The Briton will next take on Maximilian Marterer after the German defeated No. 6 seed Gael Monfils 2-6, 6-4, 6-4.
