Andy Murray is no stranger to winning hard-fought matches on the tennis court. But the three-time Grand Slam champion was playing under an emotional strain in his recent Davis Cup match in England.

The funeral for Murray's grandmother was scheduled the same day as his tennis match. Murray overcame a deficit to defeat Switzerland's Leandro Riedi 6-7 (7), 6-4, 6-4 in the group stage on Friday.

He was overcome with emotion after his victory because he was not able to attend his loved one's funeral service. "Today is a tough day for me. It’s my gran’s funeral today," Murray revealed during his post-match interview. "I’m sorry to my family that I’m not able to be there but, Gran, this one’s for you."

The 36-year-old Murray later said he spoke to his father about whether he should play or not, "and he said that she’d want you to play. He just said, ‘Make sure you win,’ so I did."

Stan Wawrinka defeated Cameron Norrie 7-5, 6-4 to level the tie, but Dan Evans and Neal Skupski beat Wawrinka and Dominic Stricker 6-3, 6-3 in their doubles match to seal Britain’s win in Group B.

Britain opened with a 2-1 win over Australia and is well-placed to reach the Final 8 in November.
