England's amazing 10-wicket win over West Indies in the first Test was down to the team doing their homework, captain Michael Vaughan said.
England skittled West Indies out for 47, their lowest ever Test total, thanks to a seven-wicket burst by Durham fast bowler Steve Harmison.
A delighted Vaughan said: "We always try to do our homework and today Steve got it right.
"Sessions like that don't come very often. We will definitely enjoy today."
Vaughan said he was stunned at the ease of the victory before lunch on the fourth day.
But he praised his team's attitude and application which gave them a 1-0 lead in the four-Test series.
Vaughan said: "We saw the sun was shining this morning and expected a really tough day,"
"We bowled well on the first day and on days two and three our application
with the bat was first class.
"Nasser Hussain and Mark Butcher's stand on that first morning we had to bat
"That allowed Freddie [Andrew Flintoff] to play the way he was able and then Matthew Hoggard hung around for as long as he did.
"This morning was all about Steve Harmison but the hard work we put in on the
first three days allowed that to happen."
Harmison said he could barely describe his emotions after taking 7-12, the best ever bowling figures at Sabina Park.
He said: "I'm really pleased. I didn't think this was going to happen when I woke up this morning.
"I learned from the first innings that my natural length
was far too short and I watched how the West Indies bowled and saw I needed to
bowl a bit fuller.
"Some good people in good places have helped me a lot. The team have worked
hard, the preparation has been excellent and it showed today.
"The other bowlers were brilliant. First innings we worked hard to bowl them
out and even today Hoggy [Hoggard] was excellent."
