Vitality County Championship Division One, Taunton (day three)
Somerset 317: Banton 132; Hasan 4-97
Surrey 321: T Curran 86, Patel 70; Vaughan 6-102, Leach 4-105
Surrey (5 pts) lead Somerset (5 pts) by four runs
Teenager Archie Vaughan took 6-102 as Somerset bowled out title rivals Surrey on day three of their County Championship match at Taunton.
The 18-year-old added the wickets of England wicketkeeper Ben Foakes, Jordan Clark and Cameron Steel to the three he collected on the second day as second-placed Somerset restricted Surrey to a lead of four runs.
But he was unable to make a similar impact with the bat in Somerset's second innings, adding only three to his first-innings 44 before being bowled by Shakib Al Hasan playing across the line.
Vaughan is the son of former England captain Michael and playing in only his second first-class match. He appeared for England's under-19 side earlier in the summer and in six games for his county in the One-Day Cup.
He bowled in tandem with fellow spinner Jack Leach, a member of the England squad for the tour to Pakistan, as the pair got through more than 85 overs.
Foakes, who lost his England Test place to Surrey team-mate Jamie Smith, was caught at short leg for 37.
Vaughan then had Clark taken at mid-wicket by Tom Abell and Steel caught behind in the space of three deliveries.
Left-armer Leach did claim the vital wickets of Rishi Patel (70) and Al Hasan (12) before Tom Curran counter-attacked reaching 50 off 33 balls.
Leach ended the innings on the stroke of lunch when Curran was caught at long-on for 86 off 75 balls, including eight sixes, Leach finishing with 4-105.
Surrey began the match 24 points ahead of Somerset, with just two rounds of games left after this one, as they look to make it three County Championship titles in a row.
