West Indies
Edwards: 5.5/10
Looked a bit more solid than his average of 26 suggests, and scored 2 half centuries, but still failed. Dropped Taylor in Wellington.
Powell: 3/10
The opening partnership was actually a strength for the West Indies, but Powell failed to even reach 50 once.
Bravo: 7.5/10
Purely for his match-saving double hundred. Did nothing else but that innings still gets him a tick.
Samuels: 4/10
Looks mentally shot. One streaky fifty for an average of 19.5, along with poor fielding and body language.
Chanderpaul: 7/10
A nice hundred and a threatening fifty, but he did get out to some poor shots. Still averaged 64.
Deonarine: 4/10
Is not a test match number six. Batted well with Bravo in the first test and bowled well, but he flattered to deceive and was never a genuine batting threat
Ramdin: 6/10
He had a great final test in which he actually looked interested and motivated, but he was very poor in the first two tests. Still managed to be West Indies' third best runscorer.
Sammy: 6/10
The fact that he was West Indies' second highest wicket taker and 4th highest run getter justifies his selection. He was also superb in the field.
Sunil Narine: 8/10
Hard not to give him a high score even if he only played the final test
Tino Best: 4/10
Tried hard. Not able to land the ball in the right areas enough. Not enough movement of the ball. Not an opening bowler.
Shannon Gabriel: 1/10
Very, very poor. Needs to re-learn how to present the seam, because he bowls at a decent clip and would actually be threatening if he could get a bit of swing or seam
Veerasamy Permaul: 3/10
I like the look of him as a second spinner but probably a better limited overs bowler.
New Zealand
Hamish Rutherford: 4/10
Again flattered to deceive but might've done just enough to retain his spot
Peter Fulton: 4/10
two very unlucky strangles down the leg side. Managed just one fifty but generally did his job of seeing off the opening bowlers. some decent slip catches.
Kane Williamson: 6.5/10
Really needs to learn to convert his starts. Despite not getting a bit score, his 45 in Wellington in partnership with Taylor was a crucial score.
Ross Taylor: 10/10
Literally could not have done more. Didn't get out for less than a century each time he batted, and was outstanding at first slip.
Brendon McCullum: 6.5/10
A nice, if unpressured century in the first test. Gave his wicket away at crucial times in the rest of his innings when NZ could've really put pressure on the opposition.
Corey Anderson: 7/10
His bowling was a revelation and makes him very difficult to drop. His batting is progressing, but still not quite there. Very much worth persisting with.
BJ Watling: 6.5/10
Showed some grit at times but also gave it away at times. Superb with the tail in Wellington. His keeping wasn't quite as good as the very high standards he's set for himself.
Tim Southee: 8/10
Continues to dominate top order opposition batsmen. 18.11 average, 2.99, economy and a superb 36.2 strike rate.
Ish Sodhi: 3/10
Is not yet test standard and shouldn't be in the team. Showed some good potential and looks handy with the bat.
Neil Wagner: 4/10
Another failure for him after a false dawn in Bangladesh. He picked up a couple of crucial wickets, but didn't take more than 3 wickets in an innings and averaged 45.5. Worse than his average was his strike rate of 71.2 and his economy rate of 3.8. He was comprehensively outbowled by Anderson.
Trent Boult: 8.5/10
20 wickets at 15.5 is superb, but he did occasionally go missing with the ball.
