Late Night Action at Citi Open

Japanese second seed Kei Nishikori's match ended 20 minutes later as he saw off Argentine Juan Martin Del Porto 6-4 7-5 to advance to the quarters, where he will face American Tommy Paul.

India's Yuki Bhambri's spirited run at the Citi Open in Washington came to an end after he lost to South Africa's Kevin Anderson 4-6, 6-4, 3-6 on Saturday.

Nishikori, victor of this tournament in 2015, prevailed 6-4, 7-5 in 1 hour, 49 minutes at the Rock Creek Park Tennis Center in Washington.

Russia's Daniil Medvedev upset Bulgarian fourth seed Grigor Dimitrov 6-4, 6-2, to reach a last-match matchup with Germany's eighth-ranked Alexander Zverev, who beat American Tennys Sandgren 7-5, 7-5 just before 2am after killing time with a nap and video games.

It was the second early morning finish in as many matches for Nishikori, who faces United States wildcard Tommy Paul next.

The 6-foot-8 South African veteran fought off a match point before serving out the tiebreaker to win 6-3, 6-7 (6), 7-6 (7) on Thursday night and improve his career record to 6-0 against the seventh-ranked Thiem. In his second Tour quarterfinal, Bhambri meets Kevin Anderson.

The Austrian then captured the next two points of the tiebreak to level the match at one set apiece and send the contest into an exciting decider.

Bhambri got broken twice in the first set as he went a set down 35 minutes into the match.

Anderson and Bhambri have never faced each other before.

"I've practiced with him before but that was a few years ago". Anderson, not wanting to waste a challenge, hesitated over what to do. "I just didn't get the feel of the serve". "Hopefully, I can win a few more matches here", Bhambri revealed.
