Been a long time

-- Vera Zvonareva, the 2010 runner-up, won her first main draw match at the tournament since 2011 when she defeated fellow Russian Anna Blinkova 6-2, 6-7 (6/8), 7-5 in almost three hours.

Bertens happy to get bent out of shape

-- Shock Cincinnati champion Kiki Bertens says she relaxes in New York by doing yoga after she's finished practice.

"Go back to the hotel, do some yoga to get back to my calmness again. Just to trying to stay calm. It's classes on my phone, yeah," said Dutch player Bertens after beating Kristyna Pliskova 6-0, 7-5.

The iceman cometh

-- Novak Djokovic said it was a "magnificent feeling" when he and US Open opponent Marton Fucsovics sat naked in separate, adjacent ice baths during a heat break.

"We had the ice baths next to each other. We were naked in the ice baths -- it was a magnificent feeling I must say to be naked with the guy you are still battling when the match hasn't finished," said the two-time champion.

Youzhny's painful finish

-- Two-time semi-finalist Mikhail Youzhny's Grand Slam career ended in a cramp-plagued retirement against fellow 30-something Marcos Baghdatis.

Volatile Russian Youzhny, 36, made the last four in New York in 2006 and 2010 and was a quarter-finalist at the three other majors having made his debut in 2001.

But on Tuesday, he could hardly walk and ended the match lying on the court after a 6-4, 6-4, 2-6, 3-1 loss.

Double trouble

-- French 29th seed Adrian Mannarino was knocked out in the first round 6-1, 6-4, 4-6, 6-4 by Frances Tiafoe of the United States and then discovered that his doubles partner Jiri Vesely had withdrawn from the tournament with injury.

Who's saying what

"I went to the Drake concert."

-- Eugenie Bouchard on how she prepared for her first round win against France's Harmony Tan.

"I just tried to cool down between games, used ice. I'm just thinking I'm on the beach, I have a margarita in hand, life is good."

-- Caroline Wozniacki on the heat problems after seeing off Samantha Stosur 6-3, 6-2 on a sweltering Arthur Ashe Stadium.

"I had heat stroke. I was not going to die on the court, tennis is not for that."

-- Argentina's Leonardo Mayer after quitting his first round match with heatstroke

"With this heat, everyone was complaining about it. So I thought it was pretty decent, like, Florida summers are way worse, I think."

-- Japan's Naomi Osaka who lives and trains in Florida

"It's a nightmare."

-- Alize Cormet who needed medical attention for heat illness
