Australia [Images] left-arm pacer Nathan Bracken [Images] feels the Indian Premier League [Images] has made batsmen smarter and well equipped to deal with bowlers at the death in Twenty20 [Images] cricket. 

"It is harder. No one is going to go out and bowl six yorkers (in an over) because the batsmen have developed and fine-tuned their 'lap' (reverse) shots," said Bracken, considered one of the best bowlers in death overs.

"Guys like Jacob Oram [Images] (New Zealand [Images]) and Albie Morkel [Images] (South Africa [Images]) have their shots. So it is important not to make a mistake, not to miss the mark. 

"I enjoy the challenge. It's what I do, but it is hard," said the left-armer ahead of the ICC [Images] World Tewnty20 starting on June 5 in England [Images]. 

Australia have been drawn against Sri Lanka [Images] and West Indies [Images] in the toughest group of league stage and Bracken admitted getting to the Super Eights would not be easy. 

"Sri Lanka has a 60 per cent win rate, while Pakistan's is incredible ... it is up around 75 per cent ... so it won't be easy. No one should be considered an easy team; we've lost to Zimbabwe in T20 before," he told Sydney [Images] Morning Herald.
