2- vs India, July 2011 - 202 not out, England won by 196 runs
The 2,000th Test match was thought sure to be Sachin Tendulkar's last at Lord's, and in many minds was supposed to be all about the Little Master.
Pietersen's first hundred runs were scratchy, the rest sublime. Collaterally, they were the difference between the two sides in a match which set the tone for a 4-0 series success as England dethroned India to go to the top of the world rankings for the first time.
