succeeding the retired Daniel Vettori as New Zealand’s specialist slow bowler, was ‘milked’ for 54 runs in 10 overs with both Cook and vice-captain Root sweeping him to good effect.
But just as he had done in last year’s Lord’s Test against India when he holed out to Ishant Sharma, Root fell into an obvious hooking trap when he failed to get over the top of a bouncer from debutant fast bowler Matt Henry and picked out Trent Boult at long leg.
Root, who made 98 in the first innings of this match, faced 139 balls including 12 fours.
England were now 232 for four, effectively 98 for four, with the first of this two-match series still in the balance.
Despite New Zealand captain Brendon McCullum setting an unorthodox 8-1 offside field, a composed Cook off-drove Henry for three to complete a 206-ball century featuring 12 fours in five hours and 20 minutes at the crease.
It meant Cook extended his England Test century record to 27 and this was his fourth Test ton at Lord’s.
