Boylesports is offering one of the most generious Australian Open bonuses we've seen this year.
Place a match bet on any Australian Open men's singles match, and if your player wins the match after losing the first set Boylesports will double your winnings as a free bet.
No opt in is required - just place your Australian Open bets at Boylesports and you'll qualify automatically.
In 2017 a total of 25 matches were won by men's singles players after they lost the first set - so you'll have plenty of opportunities to cash in.
Be aware, though, that not a single match from the quarterfinals on was won by the player who lost the first set.
