TOM Banton looks set to make his First Class debut in Somerset's County Championship clash with Surrey in Taunton from tomorrow (Tuesday).

The wicketkeeper-batsman, 19, is on standby to replace Ben Green at the top of the order in Somerset's final home match of the season after Green picked up an ankle injury in training today.

Somerset head coach Jason Kerr told the County Gazette: "Ben is a very, very, very big doubt.

"He turned his ankle this morning and it doesn't look good. We will give him every chance to prove his fitness but we have added Tom to the squad as cover.

"Tom has had an outstanding year for the Second XI and is coming off the back of nearly scoring a double ton last week [Banton made 192 from 173 balls against Warwickshire].

"It is a great opportunity for him to show what he can do."

Seamer Tim Groenewald also returns to the squad following a lengthy absence with a groin injury as Somerset look to recover from the frustration of their T20 semi-final defeat on Saturday.

Kerr said: "It was incredibly disappointing.

"Everyone was gutted in the dressing room at the fact that we didn't take the skill and ability we have shown throughout the competition into the semi-final. We didn't do ourselves justice.

"It is a thoroughly enjoyable occasion, but it was challenging and emotionally draining."

Despite the deflation that accompanied Saturday, Kerr was able to find positives both on and off the field.

"I am very proud of our campaign and what I find exciting is how much more there is to come from this group," he said.

"Tom Abell batted superbly and he has been brilliant throughout the competition. He copped a lot of stick after the defeat at Kent, so to come out and bat like that on the big stage is a mark of his character. He and Corey Anderson gave us hope until Tom's unfortunate dismissal.

"The support was brilliant and testament to how we operate as a club. The lads that weren't playing went up to support, and the players went in and sat with our fans after the match. We have incredible supporters who sacrificed a lot to come and watch us on Saturday, so we felt that was the least we could do."

The challenge is now for Somerset to pick themselves up for the visit of the newly-crowned county champions, who wrapped up the title by winning at Worcestershire last week - Surrey's ninth Championship victory on the bounce.

For a while it had looked as though this week's match in Taunton would be a title decider, but Surrey's consistency has seen them pull clear with Somerset now aiming to wrap up second place and equal their highest ever County Championship finish.

"We spoke in practice today about needing to park Saturday and be professional this week," Kerr said.

"It has been a very constructive and positive year. We haven't quite been able to get over the line in the Championship or the T20 but we have laid some very positive foundations for next year and beyond.

"We have the chance to lay down a marker this week with a good performance against the champions."

Jason Roy returns to the Surrey squad after several weeks out with a facial injury sustained when a bat he threw down in frustration after a dismissal rebounded and hit him.

Gareth Batty has also been included and could make his first Championship appearance of the season, though he may have passed on his mantle of pantomime villain among the home faithful to all-rounder Tom Curran, who labelled Somerset supporters "peasants" in a hastily-deleted tweet after his side's T20 defeat in August.

His brother, Sam Curran, is rested after his man of the series performance in England's recent 4-1 win over India.
