Kane Williamson, Henry Nicholls Double Tons Put New Zealand On Top In Second Test vs Sri Lanka

Aggressive double centuries for Kane Williamson and Henry Nicholls powered New Zealand's dominance in the second Test against Sri Lanka in Wellington on Saturday.

Williamson and Nicholls batted at a lively clip from the outset, advancing quickly from a 155-2 overnight score and barely looking troubled as they unleashed an array of attacking strokes through the first two sessions.

Having resumed on 26, Williamson struck 23 fours and two sixes before holing out in the deep off spinner Jayasuriya as he tried to escalate the scoring rate.

Nicholls marched on from his overnight 18 to reach three
