Simona Halep advanced to Round 2 of the Citi Open after dropping Sloane Stephens in straight sets.

WASHINGTON — Wearing the same bright blue shirt, Gael Monfils was followed around Rock Creek Park Tennis Center Tuesday by a pack of kids. No. 22 on the ATP tour, he has cherished his time at this venue.    

Last year, after dropping the first set of the final 7-5 to Croatia’s Ivo Karlovic, Monfils went 7-6(6), 6-4 to win the Citi Open. It was his first ATP World Tour 500 title and sixth overall. A few months later, in November 2016, he reached a career-high ranking of No. 6 in the world. 

This week, he’s back in D.C. to defend his title. Monfils is the No. 6 seed and joins three other former champions in one of the tournament’s deepest fields in years.

“I started to learn a little bit, and I started to pay more interest in watches, and now it’s been 10 years in this industry. I really hope to do something in the watch industry.”

As he continued to get involved, in 2014, Monfils became a brand ambassador for De Bethune watches, according to the Swiss luxury brand.  

The career path is an unusual sequel for a tennis player. Though Monfils doesn’t see watchmaking directly affecting his game, there are some parallels.  

“I wouldn’t say it helps my tennis game, but it helps my creativity,” said Monfils, who has dazzled fans with trick shots over the years. 

His style of play has been acrobatic, unconventional and risky at times. He has won six titles, despite reaching the finals 26 times. 

“I know that if I’m 100% mentally on, I’m tough to beat,” he…
