Coco Gauff recovers from set down against Laura Siegemund in tense US Open win

• American sixth seed beats German 3-6, 6-2, 6-4 in first round
• Gauff frustrated by Siegemund's stalling tactics in New York

Coco Gauff demonstrated poise and experience as she moved into the second round of the US Open by recovering from a set down to defeat Laura Siegemund 3-6, 6-2, 6-4 in a tension-filled encounter on Arthur Ashe Stadium that lasted nearly three hours.

Gauff, the sixth seed, became increasingly frustrated with the significant amount of time Siegemund took between points, with the German's stalling tactics initially going unpunished. On Siegemund's serve, the shot clock ticked down to zero numerous times while she continually made Gauff wait on her own serve.
