Mark Wood's lengthened run-up is paying dividends.
The England seamer bagged a maiden five-wicket haul in Tests with it in St Lucia against Windies - and then bowled economically with it in the second ODI against the same opposition.
Ahead of the third game of the 50-over series in Grenada, Wood explained to Sky Sports Cricket's Rob Key why he made the change.
"I used to have a sprinter's run-up, it was quite short and I felt like I had to be explosive all the time. I have moved it back just to get a bit more rhythm," said the 29-year-old.
"It's like an old-school fast bowler's run-up. I gather a bit of momentum and can then cruise into my bowling. The wicket now looks twice as far away. I am fitter now that I am running in further!
"It is easier on my body as I don't feel I have to force it. The old run-up worked well for me but I felt it was putting so much stress on my body that I thought it was time for a change.
"Everyone I spoke to had the same sort of feeling that it was the right time."
