New Zealand 340 and 207 for 8 (Ravindra 91*, Jayasuriya 3-66, Ramesh Mendis 3-83) need another 68 runs to beat Sri Lanka 305 and 309 (Karunaratne 83, Chandimal 61, Ajaz 6-90)

But on a day when the pendulum got a solid workout, it was Sri Lanka who found themselves in the ascendancy at the close. That was largely down to a final session in which they grabbed four wickets.

However, it had not exactly started that way, as New Zealand came out following the tea interval with renewed intent. Sri Lanka started the session with the pace of Lahiru Kumara from one end, but that was a short-lived ploy after Ravindra and Tom Blundell plundered his shortish lengths for 14 in an over. That ushered in a period of quick runs with Ramesh targeted for a pair of boundaries two overs later.

Before long, Ravindra and Blundell had added 56. At that point, New Zealand needed only 123 more with six wickets in hand. But on this surface, one was never truly in and so it proved when Blundell opted for a reverse sweep only to be bowled around his legs.

Glenn Phillips was the new man in. Given his blistering 49 not out amid a lower-order collapse in the first innings, his wicket was always bound to be crucial. As it turned out, Phillips didn't bother the scorers all that much, edging to second slip for 4 while attempting a forward defence.

Mitchell Santner batted time in order to support Ravindra's solo offensive at the other end, but he ran out of patience and drove a tossed-up delivery straight into the hands of short cover.

Into the tail proper, Sri Lanka needed little time to dismiss Tim Southee, who struggled to come to terms with the spin being extracted outside his off stump by Ramesh. After several close calls, one hit him on the back leg in front of middle and leg. The appeal was huge, but the umpire did not move. But Ramesh was able to convince his skipper to go upstairs, and New Zealand lost their eighth.

The game had undergone a similar up-and-down trajectory earlier in the day as well. Play had begun with Sri Lanka losing six wickets for 72 runs as their second innings was wrapped up inside the morning session. Ajaz took five of those in a little over an hour and Will O'Rourke, who bowled a slightly off-colour spell with the second new ball, ended with 3 for 49.

Sri Lanka, though, would finish the session with the wicket of Devon Conway, who chopped a sharp in-seamer from Asitha Fernando. But the post-lunch session once again began with the visitors fighting back.

While Jayasuriya and Ramesh were consistent with their line and length, Tom Latham and Kane Williamson were keen to sweep and use their feet to ensure the spinners didn't have it all their own way.

Williamson, in particular, was busy throughout, at times sliding deep into the crease and other times stepping out to get to the pitch of the ball. A lofted six over extra cover, with the spin, against Jayasuriya was a session highlight. Just before that, he had hit a sumptuous cover drive.

But Jayasuriya had the last laugh, dragging one shorter having seen Williamson step out one time too many, and turning it past a panicked forward defence as Kusal Mendis whipped off the bails. Such was the turn, it left Williamson briefly confused and gesticulating in frustration at the pitch as he walked off.

That ended a threatening 45-run stand between two players who had caused considerable damage in the first innings.

Before the session was over, Sri Lanka also had the wickets of Latham and the dangerous Daryl Mitchell in the bag, the former done in by Dhananjaya de Silva's an arm ball and the latter by one that spun back prodigiously from Mendis.

But then New Zealand, led by Ravindra and Blundell, fought back once more before the spinners hurt them once again.
