Talk about stamina: After Isner spent a record-breaking 11-plus hours over a span of three days slugging it out against Nicolas Mahut of France on Court 18 at Wimbledon, he won the match, 6-4, 3-6, 6-7, 7-6, 70-68.
The athletes picked up play Thursday, after leaving the court tied 59-59 in the fifth set after the match was suspended Wednesday due to darkness.
So how did Isner feel going into day three of his epic first-round match – sore, sleep-deprived, exhausted?
None of the above: The tennis star Tweeted he "feels like a million bucks!!!" just hours before heading back out on court Thursday.
Isner's match is now the record books as the longest match in the history of tennis – not bad for leaving a lasting impression on Wimbledon and tennis fans.
