National cricket selectors have cracked the whip on non-performers and axed the struggling duo of Yuvraj Singh and Yusuf Pathan from India's 15-member squad for this month's Asia Cup cricket tournament in Sri Lanka. The Selectors also rested veteran Sachin Tendulkar from the squad. Tendulkar had sought a break to spend time with his children, while Yuvraj and Yusuf's ouster was on the cards after a series of disappointing performances in recent times as the selectors laid stress on form and fitness. Flamboyant opener Virender Sehwag, who was lying low with a shoulder injury and missed the Twenty20 World Cup, returned to the squad, while wicket-keeper-batsman Dinesh Karthik and leg-spinner Amit Mishra were axed. This was disclosed by BCCI Secretary N Srinivasan said in a statement after the selectors meeting in New Delhi yesterday.
