SOMERSET are on the brink of completing a third consecutive Bob Willis Trophy victory, after centuries from Steve Davies and Jamie Overton left Warwickshire needing a miracle to avoid an innings defeat at Edgbaston.

Warwickshire, bowled out for 121 on Saturday, stumbled to 104-6 at the end of the third day's play - Somerset having posted 413-9 declared, for a first innings lead of 292 runs.

The visitors resumed on 214-6, with Davies on 56, but soon lost Lewis Gregory and Roelof van der Merwe.

That, though, only served to bring Surrey-bound Overton in to join Davies at 226-8, and together they turned a handy lead into a huge one, with a stand of 180 in just 29 overs - a ninth-wicket record for Somerset against Warwickshire.

Davies brought up his century from 150 balls, and eventually finished with 123 not out from 182 balls (16 fours) - another classy display from a player in fine form, and a repeat of the century he scored at Edgbaston in 2019.

Overton's ton - his first for Somerset - was an explosive one, the all-rounder clubbing 120 from 92 balls (15 fours and six sixes) before finally being caught off Tim Bresnan (4-99).

The declaration came 16 balls later, and 10 balls into Warwickshire's second innings they were a wicket down, as Rob Yates left a straight one from Josh Davey and was bowled.

Overton (1-22) and Gregory (2-35) reduced the hosts to 39-3, and 58-3 became 58-5 as Davey (3-19) claimed two more wickets in two balls.

Warwickshire captain Will Rhodes showed some defiance on his way to 41 but, having watched five partners depart, he was himself caught and bowled by Gregory.

Having reduced their opponents to 104-6, still 188 runs behind, Somerset sensed victory inside three days, only for bad light and rain to bring an early end to proceedings, as the last 20 overs were lost.

Overton - who now has the highest score by a Somerset number 10 in the history of First-Class cricket - said afterwards: "It was good fun. I have spent quite a lot of time with Steve Davies so it was nice for him to be out there when I got my first century.

"I have felt good in the last couple of weeks.

"I got my previous career-best last week against Northants and have found a method that is working for me at the moment and I am sticking with it.

"I'm riding my luck at times but I think you need a bit of luck now and then.

"It was good to put on that partnership and get some batting points because we haven't got all the batting points we would have liked from the first two games.

"We wanted a good lead, knowing the batting that Warwickshire have got, so we wanted to bat them out of the game completely."

Overton added: "The weather has not been great but hopefully we have still got 90 overs tomorrow if the weather is clear, so we have plenty of time to bowl them out.

"It was amazing to get six wickets tonight and we pride ourselves on our bowling.

"We feel like we can bowl most sides out. Whatever time we get tomorrow we'll feel confident we can get the wickets."
