Andy Murray has stunned the tennis world after using the underarm serve in a match for the first time in his career during his win over Spanish star Carlos Alcaraz.
Murray battled past the Spanish teen sensation – who he has tipped as a future world No.1 – 5-7, 6-3, 6-2 in a battle that lasted more then three hours.
Alcaraz, 18, who reached the quarter-finals of this year’s US Open, initially looked awestruck by the occasion as a string of unforced errors left him trailing 3-0 and 0-40 at the start of the match.
But from the verge of a double-break down he grew in confidence, and took the first set before Murray’s experience and versatility shone through.
However, the biggest talking point of the match was Murray’s audacious under-arm ace straight from the Nick Kyrgios textbook.
In the second set, Alcaraz was standing deep to return Murray’s first serve.
And Murray took full advantage with an underarm serve ace.
The crowd reacted with mixed emotions as some booed, while others cheered the tactic.
Fans on social media were just as divided to see the three-time grand slam champ use the controversial tactic so late in his career.
