Panesar double take rocks India
cricket: Monty Panesar claimed two prize wickets on his England return in India's shaky 87-3 on the first morning of the second Test at the Wankhede Stadium.
Panesar, back for his first Test since Galle in March after a clamour for his inclusion following England's nine-wicket defeat in Ahmedabad, made short work of both Virender Sehwag and then Sachin Tendulkar.
Sehwag could mark his 100th Test with only 30 runs, and the great Tendulkar -- perhaps playing on his home ground at the highest level for the last time -- mustered only eight.
