Bangladesh won because they perform well both in batting and bowling. Fielding is not that much important as it is in ODI or T20I except the fact you need to be good in taking catches at slip position or near batsmen. NZ know how important second test match will be and they will try to win the match to draw the series. The last test series between both these countries played in NZ also ended in draw 1-1.
Had the pitch in Bangladesh's Sylhet field not been spin-friendly, the result of the first match might have been different as the pace bowling from Bangladesh to New Zealand was very strong and world-class.
Throughout the entire innings of this test match, the spin bowlers dominated, especially Taijul Islam of Bangladesh, he was impeccable.
New Zealand must win the second Test if they want to defend the series.One of the best spin bowlers in the New Zealand team is Mitchell Santner.He was not played in the first test match, maybe the target of the New Zealand team will be to play him in the second test match.New Zealand's spin attack will be a little stronger if Mitchell Santner is included in the squad for their second Test match.
Bangladesh and New Zealand will face off in the second Test at Mirpur Sher Bangla Stadium on Wednesday. Bangladesh won the Sylhet test under the leadership of Nazmul Hossain Shanto. Nazmul Hossain Shanto batted well, so if the Bangladesh team can open well on Wednesday and if a big target can be given to New Zealand, then maybe they can win the series against Bangladesh-New Zealand. After losing the first test match, New Zealand team will try to play very well. Of course, if Bangladesh bats first, they will have to score good runs, then they will have to put New Zealand under pressure with good bowling, then maybe it will be possible to win the match. And if the test series is won against New Zealand it will be the first win for Bangladesh which has never won a test series against New Zealand before. The Tigers want to maintain that winning streak in the Dhaka Test as well. Of course, best wishes for the Bangladesh team, they know they play well.
