The blow torch is seriously on the spin bowlers in this next test against Bangladesh. It's unlikely the Dhaka pitch will offer the bowlers much more than Chittagong; in fact I imagine Bangladesh will demand one just like the last.
Five wickets for 344 runs between Bruce Martin and Ish Sodhi simply wasn't good enough and it should have hurt them to see Kane Williamson and his off-spinners get a roll before them in the second innings.
I'm prepared to give them a second chance and if you're a spin bowler needing to prove a point then there is no better place to do that than Bangladesh.
I mentioned before this series started that someone had to take Daniel Vettori's wickets because Vettori has terrorised Bangladesh in the past. He has taken 51 wickets at an average of 16, including five 5-wicket bags. It is simply asking too much for our good and reliable fast-medium bowlers to roll Bangladesh twice in their conditions; the spinners have to play their part, ideally a leading part.
If Martin wants some extra motivation, then he may want to realise he is effectively playing for his position. Vettori is due back and Martin has failed to set the world alight. He's been good at times but not a revelation and so Vettori will most likely oust him.
