Brook hails 'brilliant' Banton as England back on track at T20 World Cup
Banton, who had been out for two against both Nepal and the West Indies in earlier Group C matches, came in with England wobbling at 13-2 chasing 153, but carried his side to finish 63 not out in their 155-5.
"He was awesome. It was a brilliant innings," said Brook
"He's obviously matured as a player, as we've seen tonight, the way he's chased that down there single-handedly, with a couple of cameos from (Jacob) Bethell and Sam (Curran)," Brook told reporters.
"He played it beautifully."
Brook said Banton was now able to alter his approach to the game and the conditions, the hallmark of a good player.
"Everyone in the world knows he's got a very good reverse sweep," said Brook.
"So he's had to adapt his game a little to hit it in different areas, because they try to stop him from hitting that shot."
Scotland's modest total was looking to be more tricky than England would have liked as they crawled to 54-2 off eight overs in reply.
Banton then launched Mark Watt for three towering sixes in a ninth over that cost the Scottish spinner 22 runs, the pressure eased and thereafter the result was rarely in doubt.
"He's a powerful player. He's got long levers. He can hit the ball out of any ground, and he's shown that tonight," said Brook.
"He was saying he felt like Mark Watt, at that time, was his match-up, so he fancied trying to take him down.
"And that's a good sign in the middle of the battle, when you feel like you're on top and your match-up comes on and you really hit them home.
"He did that perfectly tonight."
Brook said Banton was growing into the number four batting slot.
"He's good against spin and he can hit it all the way around the ground," said Brook.
"So it is the ideal position for him going forward."
Brook's side fell to the West Indies in Mumbai on Wednesday in Group C and could not afford another defeat against Scotland if they were to keep progress to the Super Eights in their own hands.
But now a win against Italy on Monday in their final Group C match at the same Eden Gardens stadium will see England safely through.
