Still a teenager, Tiafoe is considered one of the brightest prospects seen in US tennis for some time. He broke records as a junior player and when he earned a place at the French Open in 2015 he was the youngest American since Michael Chang to do so.
Bet on Frances Tiafoe
A prodigiously gifted player, Tiafoe has the greatest potential of all six players on this list, but the question is whether he is ready to start winning tournaments yet. It may be another season before he is at that stage, but he could be worth backing to make a headline-grabbing run to the last eight of a Grand Slam, ideally one of the two hard court Slams.
Frances Tiafoe odds
Bookmakers will know all about Tiafoe’s potential but are likely to take the view that he is too young to be a serious contender to win tournaments in 2017, so expect him to be on offer at some generous prices throughout the season.
