Pietersen's spill, Broad's burst
What spot of the day
England couldn't secure the breakthrough they dearly wanted (and felt they deserved the night before) in the early overs of the second morning, but thought they'd ended the second-wicket stand when they appealed for a caught-behind off VVS Laxman. James Anderson was convinced and Andrew Strauss called for the DRS only for Hot Spot to not show a mark. The third umpire heard a noise, but decided it wasn't conclusive enough to warrant a reversal and in the 23rd over of the innings England had used up their referrals.
Catch of the day
Stuart Broad's heart would have been in his mouth as Sachin Tendulkar's edge flew towards Strauss at slip shortly after lunch. Strauss hasn't been catching many of late and had spilled Tendulkar at Lord's. This time, however, there was no need to worry as Strauss watched it all the way into his hands and Broad had bagged Tendulkar for the second time in the series. Strauss continued to look alert when he provided back-up to Matt Prior by showing fantastic hang-time to prevent four byes from a Tim Bresnan bouncer.
Flinch of the day
Although Suresh Raina played superbly at Lord's there remains enough evidence that he doesn't like the short ball. England targeted him straightaway and third ball he got into a horrid tangle against Broad which resulted in him gloving over the slips. A short while later he lobbed another rising delivery over short leg and Broad's persistence soon paid off for Anderson. Raina, caught in the crease, drove away from his body and gave a simple catch to backward point.
Drop of the day
With India four down England had a real sniff. Then came one of those moments that can define a Test. Remember Graham Thorpe dropping Matthew Elliott at Headingley in 1997? While not quite of the same magnitude, Kevin Pietersen's spill at gully off Yuvraj Singh when the batsman had 4 was a momentum-changing slip up. It was a simple catch as gully chances go but it went straight to ground. Yuvraj continued to look uncomfortable against the pace but survived and tucked in against spin. Some of that spin came from Pietersen just to make his day better.
Punishment of the day
Graeme Swann had a painful hand when the day started and he had painful figures when it ended. In fact, he has never had a worse innings for England. No wickets and being taken for more than six an over. The injury may have been a factor, but surely not a huge one as it was to his non-bowling hand. Instead, credit should go to Rahul Dravid and Yuvraj who never let him settle - much as Michael Hussey attempted to do during the Ashes. Yuvraj swept him hard and Dravid picked off any error in length to leave Swann kicking the stumps in frustration. The match referee promptly reprimanded him.
Momentum change of the day
Pitch it up, Stuart. It was a simple cry and one Broad followed at Lord's with a serious impact and now he has reaped further rewards with a Test hat-trick. England had to strike with the second new ball and Broad took it upon himself with a spine-tingling burst. MS Dhoni edged to second slip, Harbhajan Singh was given lbw when he smashed it into his pad and Praveen Kumar got nowhere near a full delivery which shattered the stumps. Broad had been the third victim in the last Test hat-trick, taken by Peter Siddle in Brisbane, and now got to savour the moment himself.
