John Isner of the United States celebrates to the crowd after his three set victory against Alexander Zverev of Germany in the mens final during the Miami Open Presented by Itau at Crandon Park Tennis Center on April 1, 2018 in Key Biscayne, Florida
John Isner found new energy and outlasted Germany's Alexander Zverev 6-7(4) 6-4 6-4 at the Miami Open on Sunday for the biggest title of his career.
The 32-year-old American was tiring noticeably in the second set but won the ninth game to go up 5-4.
The moment inspired Isner, who changed to a yellow shirt and won that set and the next for his first victory over Zverev. "I couldn't have scripted this," said the 14th seed in a courtside interview after winning every service game.
