Ben Shelton has jumped two spots to No. 10 in the ATP rankings and joins No. 4 Taylor Fritz and No. 8 Tommy Paul to give the United States three men in the top 10 for the first time in nearly 20 years.

Taylor Fritz defeated Alexander Zverev in straight sets in a rain-hit final in Stuttgart on Sunday to win his first ATP title of the season.

Taylor Fritz, who beat Alexander Zverev in the final at Stuttgart at the weekend to make a strong start to the grass court season, reclaimed his place in the top four in the ATP rankings on Monday.

Top seed Alexander Zverev reached the Stuttgart Open semi-finals on Friday, and so did Felix Auger-Aliassime by stopping German teenager Justin Engel. Zverev defeated American Brandon Nakashima 7-5, 6-4 in one and a half hours.

The incident comes just two days after Moutet and Fabio Fognini's frosty handshake following their fiery clash on Tuesday. The Frenchman came away with a three-set win in a match that included a smashed racket and a verbal exchange between the pair at the net after the contest finished.
