THORNBURY broke the record for the highest innings score in any game at Potterne's ground on Saturday, amassing a massive 414-4.
This was a mainly due to Daniel Lezar, who hit a whopping 178 not out from 120 balls, including 11 sixes.
The Thornbury innings didn’t start too well with Marc Lezar picking up a golden duck and then fracturing his hand when he went straight into nets for practice.
Chris Budd and Lezar put on 147 for the second wicket, until Budd was out on 50.
Dan Davis and Lezar put on a rapid partnership of 126, with Davis finally being caught on the boundary for 85 from 41 deliveries, having hit eight fours and seven sixes.
In-form captain Richard Trotman came to the crease and again delivered with an explosive 41.
Luke Davis (25*) then joined Lezar and these two put a further 63 more on the total.
Potterne had to go at over eight an over to win but former Gloucestershire all-rounder Ed Young smashed 119 off 79 balls before being run out by Trotman.
The hosts took the game all the way until the 49th over when a caught and bowled from Tom Shrewsbury to remove number 11 Ben Mason wrapped up a 17-run win for Thornbury.
Trotman took 3-63 for Thornbury with Sayeem Waliullah claiming 4-72.
Thornbury's last game of the season on Saturday is at home to Illminster, who need the points to gain promotion.
The seconds played Warminster at home and batted first after losing the toss.
They did not get off to a great start as both Marcus Wormwell and Kyp Bridgen were both back in the changing room without a sweat on the brow.
This left Danny Slade and Juvaunie Gayle to build the innings.
Slade accrued 92 and Gayle a magnificent 126 with James Tunnicliffe hitting another massive half-century, scoring 67 off only 27 balls in Thornbury's 354-6.
Warminster were then all out for 230 after 38 overs, giving Thornbury another convincing 124-run win.
This puts them top of the Premier Two 2nd XI table and a win against Gloucester City Winget on Saturday will see them earn promotion.
