Serena Williams demands an espresso mid-match
There isn't a lot Serena Williams hasn't done on a tennis court in her illustrious career to date - but even this was new.
Having been whitewashed 6-0 in the first set of her Hopman Cup tie with Flavia Pennetta, the world No.1 slumped in her court-side chair at the Perth Arena and knew she had to do something.
She looked up at the umpire and asked: "Is it illegal to order an espresso?"
Williams got her caffeine fix and went on to win the match 0-6 6-3 6-0.
"I am a coffee drinker and I didn't have mine this morning and I was just feeling it," Williams explained. "So I had to get some coffee in me.
"I told them to just give me a shot of espresso. I asked them if it was legal - 'Is it illegal to have a shot of espresso?' - because I had never done it before.
"I needed some espresso. I needed to wake up - the jetlag gets you all the time."
Williams had every reason to be a lethargic. She arrived on Australia's west coast for the mixed team event, where she is partnering John Isner, late on Saturday and played her first match at 10am on Monday morning - a start time Williams is not a fan of.
"My gosh, hopefully I won't have any more, or I will be pulling out … maybe a coffee sponsorship," she said.
But as her game returned, so did her smile - something she says people should get used to in 2015.
She added: "I have never smiled so much in a match before. This year my whole goal is just to have more fun.
"My dad says, 'Serena, just enjoy yourself and I promise you will play better'. So I said, 'Okay, I am trying to relax a bit more and play how I know I can play'."
