Arriving at the Millennium Estoril Open without a win since mid-February, Dominic Thiem showcased all of his resilience to battle to first-round victory on Tuesday at the clay-court ATP 250 in Portugal.

Thiem defeated his fellow Austrian Sebastian Ofner 3-6, 6-3, 6-4 to clinch his first triumph in five tour-level events. The 29-year-old made a shaky start but broke his No. 122-ranked opponent twice in each of the second and third sets to prevail in a two-hour, five-minute encounter and set a second-round showdown against #NextGenATP American Ben Shelton.

The World No. 111 Thiem converted five of 16 break points he earned against Ofner, which proved enough to close out victory and improve his ATP Head2Head series lead against his countryman to 3-0. Some flashes of trademark brilliance, particularly off his backhand win, helped engineer the turnaround.

Thiem holds a 2-8 record for the year after Tuesday’s win, which he will hope is the catalyst for improved results. The Austrian, who reached the Roland Garros final in 2018 and 2019, has historically excelled on clay. He has won 10 of his 17 tour-level crowns on the surface.
