Uncapped Essex seamer Reece Topley believes he is ready to make the "jump" to international cricket with England.
The 21-year-old, who has taken seven T20 Blast wickets this summer, is in the Twenty20 squad to face New Zealand.
"It's probably the biggest jump I've ever had in the standard of cricket, but I feel like I can contribute at that level," he told BBC Essex.
"I'm very excited about seeing how I do and it's a good time to assess where I am and what I need to improve on."
England are currently level at 2-2 in the home one-day series with New Zealand.
