Andy Murray suffered a brutal defeat last night at the hands of his 10-month-old daughter Eadie, who decided it was time to show her dad who was boss.

The tot got the better of her old man and served him with bloody nose when a game between the pair became a little bit rough. 

The incident took place ahead of the 31-year-old's US Open match against Fernando Verdasco but it seems defeating the Spaniard was the least of the Scot's problems.

Glasgow Times:

The tennis ace posted a picture on his Instagram page holding his blood-stained face alongside the caption: "When playing with your 10 month old daughter gets a bit too physical!"

Andy will take on his next opponent this evening at the Arthur Ashe Stadium.
