Zimbabwe fired a warning shot towards the heavyweights who have reached the Twenty20 World Cup Super Eight stage as they beat co-hosts Sri Lanka by six wickets to top Group B on Thursday, chasing down a target of 179 with three balls to spare, Reuters reported. 

Opener Brian Bennett scored an unbeaten 63 and captain Sikandar Raza made a quick 45 as Zimbabwe, who stunned Australia last week, handed Sri Lanka their first loss in the campaign, with both teams having already qualified for the Super Eights.

"I am pretty excited with how we have gone about our business," player of the match Raza said. "We are unbeaten so far ... nice position to be in as a captain but I will try and enjoy at least tonight."
