After 111 overs, England is 374 for 9, with Root on 88 and Anderson on 33.
Root turning down easy singles. I've always wondered about this practice. It works for some players but then others like Steve Waugh and Shivnarine Chanderpaul like to rotate the strike no matter who is batting.
I suppose it depends on the quality of the tailender at the other end. Waugh reckoned empowering them and giving them responsibility made them rise to the challenge.
FOUR! Root flashes hard and the edge beats the man on the third-man boundary. Root moves to 92.
He takes off for a desperate single to mid-on, who misses the stumps at the non-striker's end. A direct hit and Root would have been out by a significant number of yards.
Perhaps Root should have more trust in Anderson, who has been out for over an hour and faced 46 deliveries for 33 runs.
Rahul Dravid and Harsha Bhogle present Sanjay Manjrekar with a tray full of birthday sweets. Manjrekar turns 49 today.
This pair has already added 27 runs from 6.3 overs this morning. Eating up runs and time is England.
FOUR! Top shot. Root strides forward and with the high-left elbow crunches Shami through the covers.
FOUR! Hundred for Root! He places the ball the other side of point and gives Anderson a bear hug.
FOUR! It is raining boundaries now. Anderson upper cuts Shami over the slips.
Anderson is now on 37, surpassing his previous Test best of 34. His partnership with Root now worth 93. England trail by just 66. A result in this Test becoming more remote with each passing delivery.
A silly mid-off is now in place for Anderson against Ishant.
FOUR! Ishant pitches it up and Anderson flails him through the covers. He is enjoying himself now. That is his innings four of his innings, meaning 36 of his 41 runs have come in boundaries.
This is now Anderson's highest first-class score. Remember, Shami, India's No. 11, made his highest first-class score in the first innings.
Shami continues at the other end. He replaced Bhuvi Kumar an over ago.
Root drives through the covers for two to bring up the 100-run partnership for the last wicket for England.
England one away from 400. This Test turning to be the tail of the tailenders.
Dhoni has surrounded Anderson with a number of close-in fielders.
Anderson has something in his eye. The umpire is taking a look.
Ganguly makes the point on commentary that bowling sides have to attack both batsmen. They can't just settle for attacking the tail-ender.
FOUR! Somehow Anderson tucks a short ball between leg-slip and leg-gully to move to 45.
Another short ball that Anderson fends just short of the diving fielder at gully. He picks up a single to keep the strike though. Will he get to his fifty?
That boundary too England past 400. The odds on a draw rapidly diminishing.
At one point, England were 202 for 7. That tells the story.
Ishant going wide to Root, who follows him but misses the slash.
FOUR! Dhoni brings up the field up for the last ball of the over. Root promptly crashes Ishant past point.
England doing to India what India did to England.
Root and Anderson have now added 111, the same as Bhuvi Kumar and Shami.
Anderson to face Shami. Dhoni has practically everyone in catching positions around the bat.
Only a third man is on the boundary.
This is a remarkable field.
Shami wastes a couple of bouncers.
FIFTY FOR ANDERSON! He charges Shami and smashes him to vacant midwicket. His 1st ever Test 50.
Another big hug between Anderson and Root. Taken Anderson just 61 deliveries and included 11 fours. He has a strike-rate of 82.25. As a No. 11. This has been a crazy Test match.
