World Cup 2019: Top 5 tournament debutants to watch out for

#2 Jason Roy

West Indies v England - 1st One Day International

England is certainly going into the world cup as the favorites. And while they have quite a few match winners in the squad, the dominance of Jason Roy as an opener is what they'll be betting big time in the upcoming World Cup.

Since making his debut on May 8, 2015, Roy has amassed 2661 runs in 73 ODI appearances at an average of 38.56 and a smoking strike rate of 105.51. As 300+ totals is a norm these days, Roy has become England's chase-master helping them successfully chase down massive totals.

It's his destructive nature of play that helped England chase down 305 in Melbourne, against Australia, last year. His record-breaking 180 off 151 balls helped England cruise their way to victory with 7 balls to spare.

This year he scored a 65-ball century to set up another successful massive run chase against the West Indies in Barbados, where England managed to chase down 361.

#3 Kagiso Rabada

South Africa v Sri Lanka- One Day International

Kagiso Rabada, the fiery South-African speedster about whom Alland Donald is certain that he's well on his way to becoming South Africa's all-time greatest fast bowler, is another exciting World Cup debutant.

Making his ODI debut at the age of 20, Rabada has picked up 106 wickets in 66 appearances at an average of 26.43. He's currently at No. 5 in ICC's ODI Bowling Rankings. Last year, he was awarded Wisden's Golden Boy award, a yearly honor which goes to the best Under-23 male cricketer in the World.

In a pace attack studded with the likes of Dale Steyn and Vernon Philander, Rabada is the X-factor.
