Yorkshire go into their C & G quarter-final clash against Warwickshire as strong favourites.

They inflicted on Warwickshire their lowest ever one-day league score on Monday night, and will be strengthened further by the return of England players Gough and White – if selected.

They beat a strong Surrey side in the previous round too, and are runaway leaders in the CricInfo Championship. But they are taking nothing for granted and are still looking to improve in some areas.

"The lads have been buoyed by the result against Surrey, but we're still conscious of areas of weakness," David Byas, the captain said.

"We batted brilliantly at the end, but the performance in the first half of that game, when we were fielding, was woeful. We'll be hoping to cement our game, maybe we need to relax and chill out more.

"But it will be a difficult fixture against Warwickshire. I've not seen much of them this season but they're a wonderful one-say side and their record speaks for itself. It's anybody's game.

"This is our last chance at a one-day trophy this year so we'll be keen to succeed."

Meanwhile Warwickshire coach, Bob Woolmer, admits that Monday's debacle is a factor in this game.

"We'll have to pick our strategy carefully as there will be a few factors involved, like the pitch, the weather and Monday's result," he reasoned.

"It's good to get to the quarter-finals in any competition and we've done pretty well in the Trophy in recent years. It's a big game and we're playing good cricket at the moment, which we want to carry forward into it.

"And although Yorkshire have had something of an up-and-down season in the one-day game, they're still a very good side. I thought they were struggling against Surrey in the last round, but in the end they cruised to victory."

Lancashire go into their C & G quarter-final game against Durham in confident form.

"We're going to approach the game in a very aggressive, very confident manner," Lancashire coach Bobby Simpson said.

"I think we've turned the corner now, we're out of the maze in terms of the one-day game. We've started to play very well and we're obviously growing in confidence. And once you get on a run in this competition, you fancy you can go all the way."

Lancashire's headquarters, Old Trafford, is being used for a Robbie Williams concert, so the teams meet at Blackpool Cricket Club. But far from bemoaning the waste of home advantage, Simpson claims to be glad of a trip to the seaside.

"It's a good ground," he insists. "There'll be a good crowd up there who'll provide some fantastic support. It should be packed out."

Durham coach, Martyn Moxon, acknowledged his side's record against Lancashire this season, but refused to read too much into it.

"We've beaten them twice already this year but that won't have too much bearing on the outcome of this one. Like every other game we'll start at 0 for 0 on the day. But we won't be over-confident as we know Lancashire are one of the best teams in the country and their record in one-day cricket is very good, so we'll have to play at our best."

Steve Harmison is out for the visitors with a chest infection, while Nicky Phillips is out with a broken finger.

Kent host Somerset at Canterbury. Kent captain, Matthew Fleming, is an injury doubt for the game but believes that his side will pose awkward opposition for the West Country side.

"We've already beaten Somerset once this season, and tied with them on another occasion so I'm sure they'll be talking about us as much as we'll be talking about them," Fleming said.

"It would be nice to go to Lord's this year but we're still two games away from that. We're having a good season and it would be lovely to win. But we are near the top of the National League and doing well in the CricInfo Championship.

"So although every game is important, if we lost this one it wouldn't be the end of our season by any means."

Somerset are boosted by the return to county ranks of their Test players, Trescothick and Caddick.

It was Trescothick's brutal innings of 121 from 83 balls that eased his team into the quarter-finals and captain, Jamie Cox, is delighted to have him back.

"He'll be a key player in every side he's in for the rest of his career," Cox said. "And he's a fantastic player for our side. We're going okay at the moment, although we've dropped a few games we shouldn't have this season.

"It's too early to start talking about silverware but we've certainly got a side capable of winning this competition. We've been close in the last couple of years and we've had nothing to show for it, so we'll be trying like hell to put that right."
