Head made a massive 175 off 139 balls as he inspired the Vikings to their highest ever total.
After navigating the first 20 overs with caution, Head unleashed four huge sixes between long-on and square-leg on the way to recording the second highest List A individual score.
He was just 16 shy of Darren Lehmann's record of 191 against Notts at Scarborough in the 2001 45-over National League.
150 for @travishead34 off 130 balls with 16x4s and 2x6s. 299-2 now. Record stand of 248 for county in all List A cricket.

In another record-breaking feat, his third-wicket stand with Jack Leaning totalled 274 inside 37 overs to become the county’s highest ever List A partnership.
The 22-year-old is clearly making the most of the Australian off-season before returning to Adelaide for BBL 06.
Adil Rashid also starred for the Vikings, taking 3 for 23 as the Strikers pair continue to light up the county cricket stage.
