WORCESTERSHIRE Rapids could not produce their A game as they were crushed by nine wickets in the Royal London One-Day Cup quarter-finals at Somerset.

Mahela Jayawardene hit his 21st List A century as the hosts cruised into the semis at Taunton.

A one-sided contest saw Rapids bowled out for a meagre 210 with only England international Moeen Ali (81) and skipper Daryl Mitchell (64) making any impression.

Both fell to Peter Trego (3-33) and there were two wickets each for Craig Overton and Josh Davey.

Under no pressure to score quickly, Jayawardene (117 not out) and Jim Allenby (81) replied with an opening stand of 188 in 33.1 overs, guiding the hosts towards victory with more than 13 overs to spare.

Former Sri Lanka captain Jayawardene hit 14 fours and two sixes in a batting masterclass.

Allenby gave solid support, hitting 10 fours and a six in his 96-ball innings, as no Rapids bowler could find any penetration on the used pitch that had seen their side bowled out inside 43 overs.

The skipper eventually top-edged a sweep off Moeen to deep backward square with the job almost done.

Somerset had won the South Group and Rapids were never able to get much momentum after winning the toss.

Overton and Davey, playing in place of the injured Tim Groenewald, produced accurate opening six-over spells, which reduced the visitors to 40-3.

Tom Kohler-Cadmore (2) was brilliantly caught at slip by Jayawardene off Overton, while Davey struck twice in one over, removing Tom Fell (15) to a catch at backward point and Joe Clarke (2), who chipped tamely to mid-wicket.

Moeen and Mitchell put the pitch into perspective with a stand of 113 in 19.4 overs with the former continuing his Test match form with an elegant 76-ball innings featuring 10 fours and a six.

He survived just one run-out scare before miscuing a pull shot off Trego and being caught by Max Waller at deep mid-wicket.

At 175-4 with 17 overs to go, Rapids looked reasonably placed.

But Mitchell, who had played the perfect supporting role to Moeen with a 67-ball half-century, was then well caught above his head by the retreating Davey at mid-off to give Trego his second wicket.

It sparked a collapse with Ross Whiteley caught behind in the same over and Ben Cox quickly falling to Lewis Gregory, both for two-ball ducks.

The last hope was Brett D'Oliveira and when he fell to Overton for 21 the innings was in tatters.

Joe Leach managed 20 before being run out by Roelof van der Merwe, who wrapped things up by pinning Jack Shantry lbw.

There were more than seven overs still available and the total looked 70 below-par — and so it proved.
