2017 ATP Shenzhen Open

The 2017 ATP Shenzhen Open was a professional men's tennis tournament played on hard courts. It was the 4th edition of the tournament, and part of the ATP World Tour 250 series of the 2017 ATP World Tour. It took place at the Shenzhen Longgang Tennis Centre in Shenzhen, China from September 25 to October 1.

Dudi Sela, Israel's # 1 player quit his quarterfinal match in the third set of the 2017 Shenzhen Open so he could begin observing Yom Kippur—the holiest day of the Jewish year—by the time the sun set, forfeiting a possible $34,000 in prize money and 90 rankings points. He had asked the tournament organizers to have his match be moved forward to be completed before sunset to accommodate his religion, but they denied his request.
