Dubai Tennis Championships Day 1: First-round updates from the WTA 500 event

The 2022 Dubai Duty Free Tennis Championships is underway, with a stacked field competing at the WTA 500 event.

Day 1's first round is headlined by two-time champion Simona Halep's match against American qualifier Alison Riske in the first evening match on Centre Court. Also in action are world No 9 Iga Swiatek, French Open champion Barbora Krejcikova, and American teenage sensation Cori Gauff.

American teenager Cori Gauff was eliminated from the first round of the Dubai Duty Free Tennis Championships on Monday after going down to compatriot Jessica Pegula 6-4, 6-4 on Centre Court.

In a match that saw both players struggle to hold serve, 17-year-old Gauff made Pegula work for the victory in a final game that contained four match points and two break points.

Pegula, the world No 14, quickly raced into a 3-0 lead in the first set but soon joined Gauff in having trouble holding serve as the teenager levelled at 3-3. Pegula immediately broke again to regain control and claimed the opener after both players held serve.

The struggles on serve continued into the second set, the first four games going with the returner, until Pegula edged in front again with a break and hold to lead 5-3. After a Gauff hold, the Australian Open quarter-finalist saw three chances to wrap up the match come and go and had to fend off two break points before ultimately taking the win in exactly 90 minutes.

Pegula will face either Tunisian eighth seed Ons Jabeur or Russian wildcard Vera Zvonareva for a place in the quarter-finals. While Gauff's singles campaign ends at the first hurdle, she will link up with Pegula to compete in the doubles.
