A crafty drop shot chalked up two set points for 6-4, but this time it unravelled. The Brazilian missed a routine forehand putaway and a simple overhead, gifting four points in row to allow the world No.2 to level.
The 2021 US Open champion's winning mentality clicked in and Medvedev scuttled forward to scoop a backhand crosscourt pass from down by his shoeslaces. His skills earned a thumbs up from Seyboth Wild as it seemed increasingly likely that Medvedev would march through to the finish.
But not so fast. The Brazilian, a two-time winner at ATP Challenger clay court tournaments this season, coped with the swirling wind and kept Medvedev off balance and off kilter.
The decider had the initiative switching hands until a firecracker forehand launched Seyboth Wild 4-3 up. The 23-year-old consolidated his advantage with a dinked volley to hold to love. It was time for Seyboth Wild to soak in the applause and revel in his finest moment.
