Andy Murray won the famed tennis tournament, ending a long drought for the Brits, when he became the first British man to win Wimbledon in 77 years.
"I understand how much everyone wanted to see a British winner at Wimbledon so I hope you enjoyed it," Murray told the crowd after the match, according to USA Today. "I tried my best."

"Oh my God. What a match, what a player. Inspiring a Nation. .Andy Murray!! Ya Beauty," McGregor wrote.
