Serena Williams: Remembering when tennis star ordered an espresso mid-match

There have been plenty of iconic Serena Williams moments over the years, but do you remember the time she ordered a coffee during the middle of a match? 

Back in 2015, the former world number one was competing against Flavia Pennetta in the Hopman Cup, when she suddenly felt the need for a caffeine fix. 

Williams had lost the first set 6-0 and clearly thought that an espresso shot would give her the boost of energy needed to turn things around. 

Before the start of the second set, the American turned to the umpire and asked: “Is it illegal to order an espresso?” 

Evidently, this was not something the chair umpire was used to answering but after it was established that drinking coffee was not against the rules, Williams was quickly brought the espresso she craved. 

Remarkably, the coffee had the desired effect and Williams went on to win the next two sets 6-3 6-0. 

Speaking afterwards, the 23-time time Grand Slam winner explained that she’d been suffering from jetlag during the match, having arrived in Australia less than 48 hours before her match against Pennetta.
