New Zealand Cricket has brought back its fast bowling challenge. Boys and girls aged 15 to 18 film their fastest ball on a phone, and the quickest bowl at the Basin Reserve during an international match.

In the original challenge in 2008, Lockie Ferguson finished second to Jimmy Neesham, both over 130 km/h. This time Lockie fronts it with the Yorker app, and Pitchwolf measures the speed of every ball entered.

How your speed is measured

  1. Step 1
    Film it in the Yorker app

    Side-on, in slow motion at 240 frames a second, with the stumps and crease in the picture.

  2. Step 2
    It comes to Pitchwolf

    Every ball you enter is sent to us to measure its speed.

  3. Step 3
    A person checks it

    Our team reviews every delivery before the speed goes back.

  4. Step 4
    Your speed comes back

    Your speed and a slow-motion replay land in the app, and the fastest go on the leaderboard.

“With video capturing side-on at 240 frames per second, we believe the data is really accurate and reliable.”

Entries are still open, and every new ball can change the order.

How to film your fastest ball

  • Side-on to the crease, phone in landscape and held still.
  • Slow motion on, at 240 frames a second.
  • The stumps and the crease in the picture, so the ball's flight can be measured.
  • One ball per clip, in good light and not into the sun.

Bowl fast for longer

“We want to bowl safely, because the longer you stay on the park, the faster you'll get over time.”
