BANGALORE: Yuvraj Singh produced a stunning all-round show to become the first player to grab a five-wicket haul and score a half century in the World Cup as India pulled off a nervy victory over Ireland Sunday. Yuvraj took his first five-wicket haul to help India bowl out Ireland for a modest 207 and then followed that up with a responsible knock of 50 of 75 balls to steer his team to a five-wicket victory, ensuring they stay unbeaten in the tournament. The 29-year-old and his captain Mahendra Singh Dhoni (34 in 50 balls) played uncharacteristically sedate knocks and stitched together a 67-run partnership to set India well on their course to victory. The duo came together with India precariously perched at 100-4 after Sachin Tendulkar (38) and Virat Kohli (34) fell in quick succession. Following Dhoni's dismissal, Yusuf Pathan blazed a quickfire 30 off 24 balls with three towering sixers to finish off the match. Yuvraj took over after Zaheer Khan gave India the perfect start by bowling Stirling in the first over of the day and removing Ed Joyce in his next over. He finished with three for 30. Ireland skipper Porterfield top-scored for his team with a fighting 75 in 104 balls and Niall O'Brien (46) steadied the innings with some determined batting mixed with pugnacious strokeplay in a stubborn 113
