Tom Banton shines as Somerset's hero before being sidelined for T20 Finals Day

Somerset shook up the County Championship Division One title race with a stunning victory over leaders Surrey at Taunton. The thrilling day-four finish saw Somerset claim a crucial win, but it came at a cost as Tom Banton suffered an ankle injury while playing football. Unfortunately, this means he will miss the upcoming Blast semi-final rematch between the two teams on Saturday.

Banton batted at No. 11 in Somerset's second innings, scoring 46 in a vital last-wicket stand with Craig Overton worth 71. Surrey then collapsed from 95 for 3 to 109 all out in the final session of the game, Somerset securing victory with minutes left in the day to cut the champions' lead at the top to eight points.

Speaking before the extent of Banton's injury was confirmed, Jason Kerr, Somerset's head coach, conceded that it was "pretty serious", adding that James Rew would be added to their squad as wicketkeeping cover.

"Tom is an incredible talent, but so is James and we believe he has a bright future in all formats," Kerr said. "Yesterday was a fantastic day and we need to use the confidence and momentum from that tomorrow. We know that anything can happen in the short format of the game, but the confidence in the group is extremely high and it's a challenge that we're all looking forward to."

Aside from Banton, who top-scored with 132 in the first innings, Somerset's heroes were Archie Vaughan - the son of former England captain, Michael - and Jack Leach. Vaughan, playing only his second first-class match, claimed match figures of 11 for 140, while Leach took 9 for 142.

Somerset's dramatic victory kept them in touch with Surrey, the two-time defending champions, and maintained their hopes of winning a domestic treble, having also progressed to the One-Day Cup final later this month.

"It was a crazy hour at the end," Somerset captain, Lewis Gregory, said. "There were periods when not much happened, but the lads hung in there and Jack Leach and Archie Vaughan were fantastic the whole game.

"To get a win with only a couple of minutes left in the match was very special. Four-day wins are some of the most pleasing you have as a cricketer because you work so hard for them.

"Archie has taken to first-class cricket like a duck to water. The fact that he is more of a batter than a bowler is the really exciting bit and we believe he is going to be very good to watch with the bat over a number of years. If you throw in the off-spin he has bowled in this game, there is a mighty special cricketer developing.

"Leachy is a great mate of mine. He has been through a good deal of adversity in his life and not just his cricket career. It's great to see him back in the England squad and I'm sure he will show what he can do in Pakistan.

"The coaches and myself said at the start of the season that we wanted to be in a position to challenge for trophies come September. The fact that we can still win three shows the calibre of players we have in our dressing room."

Although Surrey had their lead at the top cut, they remain in control of their own destiny with two rounds of the Championship to play - a home fixture against Durham and a trip to Chelmsford to play Essex.

"We had a concentration lapse for the last hour of the game and it cost us the result," Surrey head coach, Gareth Batty, said. "It was a very good game of cricket and we played our part in it, but Somerset deservedly take the points.

"We are still top of the league and eight points clear. And, while we had a poor hour, there were still lots of positives to take from the game for us.

"Archie Vaughan bowled nicely, but it is for Somerset to comment on his performance. It's a really nice start for the lad and we wish him all the success for the future.

"It will stay in the dressing room how we are feeling. We are a very tight unit and we will go into next week incredibly confident that we can do what is required at The Oval.

"We meet Somerset again at Finals Day on Saturday. It will be a different format and different colour ball, but both teams have played good cricket in the group stages. There will be a few new faces in the match-ups and we will go again."
