Sinner avenges Shelton loss at Shanghai Masters

SHANGHAI — Jannik Sinner avenged his defeat to Ben Shelton in the fourth round of last year’s Shanghai Masters with a 6-4, 7-6 (1) victory, spoiling the 22-year-old American’s birthday Wednesday.Like last year, the duel again featured some incredible shot-making and serving dominance but this time the 23-year old Italian prevailed to improve his record against Shelton to 4-1.”Happy how I handled this situation, it’s obviously a position where I have been last year, and where I am right now, it’s different, so I’m happy to be in the position where I am,” Sinner said.Sinner’s break in the ninth game was all that separated the duo in the opening set. Both players then dominated on their own serve through the second before the Italian sped away in the tiebreak and won the last seven points of the match to advance to his seventh ATP Masters 1000 quarterfinal of the year.Editor’s Picks1 RelatedHe will play fifth-ranked Daniil Medvedev, who earlier beat longtime rival Stefanos Tsitsipas…
