Explosive left-hander Rinku Singh has emerged as a "contender" for the finisher's spot in India's T20 World Cup squad, according to Ashish Nehra, but the former India pacer also believes that the batter will face stiff challenge for the position from fellow players. The T20 World Cup will be played in the West Indies and the USA in June next year. Rinku has been in consistent quick-scoring form in the ongoing five-match T20I series against Australia.
