Kiran Carlson won the toss for the first time in seven games and decided to bowl with an unfamiliar attack short on pace, while the Foxes changed three of their seamers.

An action-packed first hour saw Sol Budinger blast 33 off 19 balls, mainly off the medium pace of Andy Gorvin, before carving him to third man where Norton took a fine diving catch.

Rishi Patel fell to the economical Zain Ul Hassan for six and Abergavenny product Norton then claimed the prime wicket of Pakistan captain Shan Masood as his first county scalp, lbw for 18.

But Leicestershire’s experienced pair of Hill and Handscomb went on the counter-attack. adding 84 in 13.1 overs before Handscomb was run out by a Henry Hurle direct hit.

Hill was still going strongly and forcing plenty of bowling changes, but Norton had him caught behind after hitting nine fours and a six in a dominant knock.

When Sam Wood (16) was run out by Tribe, the Foxes had to regroup before the final assault.

But Liam Trevaskis fell to Norton and Franco took the last three – fellow North Walian Roman Walker for 17, Chris Wright for 14 and Alex Green for 21 in the last over.

Glamorgan’s reply saw Eddie Byrom (23) and Carlson (29 including three sixes) start strongly but fail to kick on as another 18-year-old, Alex Green, took two of the first three wickets.

Green had Will Smale caught off a no-ball and that proved expensive for the Foxes as Smale started in unusually restrained fashion, playing a support role to Tribe.

The Jersey opener, who had batted through 50 overs for his 122 not out at Worcester, reached three figures off 109 balls in another mature display.

Smale finally unveiled his ramp shot and opened up to pass 50 off 64 balls as the home side accelerated, with a dropped chance off Matt Salisbury on 68 probably coming too late to matter.

There was no pressure on the run-rate in the closing stages and Tribe appropriately hit the winning four with 26 balls to spare.
