French Open 2018: Jared Donaldson serves UNDERARM to Grigor Dimitrov - and wins!
Jared Donaldson had to resort to serving underarm against Grigor Dimitrov
The American was expected to lose comfortably to Dimitrov, who is ranked 52 places above him in the world, but twice took a set lead to threaten an upset.
But twice the Bulgarian pegged Donaldson back and the 21-year-old began to struggle physically as the match ticked past the four-hour mark.
And with the chance a point on his serve to take 7-6 lead, the American produced a cheeky underarm serve which Dimitrov could only return long and give Donaldson the game.
Some fans criticised the move for its “lack of etiquette” but the tactic is a perfectly legitimate one within the rules and helped the struggling Donaldson to a crucial hold.
