Andy Murray happy to tick a mental box after Washington…

Murray is playing just his third event of the year after Queen's and Eastbourne, and it's his first hard court tournament since Indian Wells last year.

"I'll have to play much better if I want to win that match, more aggressively", Murray said. "It was nice to get it".

"I don't know all the details or numbers and the actual facts of how much everyone individually gets tested", Murray said.

That seems to have disturbed his momentum as he conceded the game before Murray held on to one of his own before going on to win 3-6 6-4 7-5. The 31-year-old Scotsman, now 832nd in the rankings, booked a second-round match against British fourth seed Kyle Edmund, who had an opening bye. "If I stay fit and healthy, I'm not anxious so much about ranking".

Former world number one Andy Murray celebrated a winning return after rallying to beat Mackenzie McDonald in three sets at the ATP Citi Open. There was still another match left to go in the main stadium, and it involved another three-time major champ: Stan Wawrinka, who faced American qualifier Donald Young.

"I enjoyed getting through that one - obviously, you see by the celebration", Murray said after a match that began a little past 10 p.m. Monday because of a rain delay, and ended at 12:45 a.m. Tuesday. "Like I said, I've not played a hard-court match for a very long time", Murray said.

Now ranked 832 in the world, Murray composed himself and broke serve in the opening game of the second set, only to hand the break straight to McDonald.

Murray broke back immediately for a 6-5 lead following a controversial call when McDonald's racket was adjudged to have crossed the plane of the net at 30-30.

Murray earned five match points but he was unable to put away McDonald, who used his second break point to stay alive on centre court. McDonald then hit a forehand long to give Murray another chance to serve for the match.

Elsewhere American Tim Smyczek won his rain-interrupted match against Lithuanian Ricardas Berankis 7-6 (4) 6-2 and will next face Mischa Zverev, who defeated Smyczek in three sets at the Atlanta Open last week. There was a cross-court passing victor at just the right angle.
