JACK Leach and Jamie Overton claimed four wickets apiece as Somerset saw off Nottinghamshire by 132 runs, securing a seventh County Championship win of the season which keeps them top of the Division 1 table.

The visitors were set a target of 225 to win at the Cooper Associates County Ground, but were bowled out for 122, with spinner Leach taking 4-42 and seamer Overton 4-24.

Earlier in the day, Somerset were dismissed for 169 in their second innings, as Ravichandran Ashwin claimed 5-59 and fellow spin bowler Liam Patterson-White – on his First Class debut – took 5-73.

Azhar Ali was resolute at the crease, finishing unbeaten on 65 to help set Notts a challenging target on a pitch offering some turn, but not as difficult to bat on as the scores suggested.

Somerset began day three of the match on 7-1, making their way to 56, at which point Tom Abell (24) was brilliantly caught by Ben Slater.

The home side then imploded, with a series of poor shots against Ashwin and Patterson-White – James Hildreth, Tom Banton and George Bartlett all falling for single-figure scores.

Steve Davies followed, and at lunch the hosts were on 108-6, a lead of 193.

Azhar moved to a priceless half-century from 157 balls, well supported by Overton (24) in a ninth-wicket stand of 51.

Leach struck early in the Notts reply, taking the new ball for the second over and pinning Jake Libby lbw with his first delivery.

Slater fell to a fine juggling catch by Banton at short-leg off Leach and tea was taken with Notts 31-2.

Overton had his first wicket when Tom Moores (22) was taken at slip for 22 – Hildreth's first of three catches on the day.

Dom Bess (2-34) and Leach saw off Steven Mullaney and Samit Patel, respectively, and it was 95-6 when Ashwin, who had batted soundly for his 41, chipped Leach to Bartlett at mid-on.

Somerset had fielded brilliantly and next it was Gregory diving on the backward point boundary to hold a chance offered by Ben Duckett, off Overton.

Luke Fletcher skied Bess to mid-off and Patterson-White was bowled by Overton, who also cleaned up Jake Ball to end the game shortly after the extra half hour was taken.

Somerset collected 22 points from the match to sit 15 points ahead of Essex at the top of the standings.

Essex were eight-wicket winners over Yorkshire, who host Somerset at Headingley from Saturday (July 13).
