The Zverev brothers are in the hunt to win weekend ATP titles.

Samantha Stosur won her first title in two years on Saturday at the Internationaux de Strasbourg, coming from a set down to hold off countrywoman Daria Gavrilova, 5-7, 6-4, 6-3 for her ninth career title.

Two Top 10ers make Istanbul the top event this week…The Top 4 seeds receive opening-round byes…Matches to watch for in the 1st rd. include (5) Troicki vs. the big-match Baghdatis, and (8) Darcis vs. Sela to see who can hit their way out of that paper bag…

Potential tough starts for (16) Lopez vs. G-Lo, and (9) Gasquet vs. (WC) Robredo…Wildcards were awarded to Murray, Robredo, Zverev, Albert Montanes, and Mikael Ymer…

Interesting starts for (1) Sock against the Haas-Opelka winner, (6) Lopez vs. the former French juniors winner Fratangelo, (4) Johnson vs. the experienced dirt-baller and defending champ Monaco, (5) Verdasco vs. the big-serving South African Anderson, and (8) Bellucci vs. the emerging American Tiafoe

Holy cow, a rockin’ seeded field, and even more floaters…First round looks for (1) Djokovic after a long layoff vs. the dangerous Klizan (winner to likely meet Del Potro), (4) Thiem vs. the backboard Simon, (5) Goffin 2nd. rd. vs. the Edmund-Querrey winner, (8) Isner vs. his American compatriot Johnson, (3) Cilic vs. the unpredictable (WC) Dolgopolov, and (2) Nadal vs. the streaking older Zverev..

The brothers Zverev couldn’t hold leads today in Rotterdam.

“It’s great to win singles and doubles,” the younger Zverev said. “I’m very happy the way we played. We only dropped one set in the tournament. I think it was a very successful tournament for the Zverevs.”

Tops 10ers Cilic and Thiem lead the field…The match of the tournament could be the first-round blockbuster (2) Thiem vs. the young riser Alexander Zverev…Other openers of the interest include (1) Cilic coming off an early loss last week vs. the mercurial Paire, (4) Berdych after opening against a qualifier vs. the Gasquet-Troicki winner, (8) Pouille vs. the veteran Kohlschreiber, and (5) Dimitrov challenged by the older net-rushing Zverev…

Thiem the only Top 10er, and Dimitrov must have received a chunk as he decided to return to his home-country tournament in 2017 after a perceived diss last year…

“I like when he puts in a nice volley past me,” Federer said. “I just think it’s a nice play, there’s nothing you can do about it. Then you move on. That’s why maybe I stayed as calm as I did today. Maybe it has helped me, too, in my comeback, no doubt about it.”

“I don’t know how I did it,” the 29-year-old Zverev said. “I was like in a little coma and serve and volleying my way through it. I think you should tell me how I did it because honestly there were a few points where I don’t know how I pulled it off, I don’t know how I won some points but somehow I made it.”
