Marin Cilic celebrated his 27^th birthday on Monday as he prepares to make his debut at the Shenzhen Open.

The second seed will open his campaign later in the week against John Millman. Millman was leading Ernests Gulbis 7-6(7), 2-0 when the Latvian retired from their first-round match on Monday due to a wrist injury. It will be Cilic’s first meeting with the No. 75-ranked Millman, who notched his third tour-level win of the season.

American Austin Krajicek set a second-round clash with top seed Tomas Berdych as he claimed a 5-7, 7-6(6), 6-1 victory over James Duckworth. Krajicek trailed 2-4 in the tie-break, but finished strongly to prevail in two hours and 28 minutes.

Australia’s Matthew Ebden, China’s Zhizhen Zhang and Japan’s Takuto Niki and Hiroki Moriya all came through the final round of qualifying to earn main draw berths in the second edition of this ATP World Tour 250 hard-court tournament.

Inglot Notches 100^th Win

Dominic Inglot claimed his 100^th tour-level win as he and partner Robert Lindstedt reached the second round with a 6-3, 6-4 victory over Victor Estrella Burgos and Nicholas Monroe.

The British/Swedish duo have compiled a 9-1 record in their past three tournaments, lifting their first team trophy in Winston-Salem (d. Butorac/Lipsky) and reaching the US Open semi-finals (l. to Dodig/Melo).
