Feisty off-spinner Harbhajan Singh became the first number eight batsman in Test cricket to slam back-to-back centuries in a match as India took a sizeable lead against New Zealand on the fourth morning of the second Test here today.

Harbhajan slammed 111 off 116 balls and his record 105-run partnership for the 10th wicket with S Sreesanth helped the hosts take a first innings lead of 122 before Daniel Vettori castled the number 11 bat to put the brakes on India's innings at 472.
