Will Beer and Michael Yardy bowled Sussex to a five-run NatWest T20 Blast victory over Somerset at Taunton.

The two spinners shared five wickets for 46 runs as the hosts plunged from a promising 78-1 to 96-6, chasing what looked a reasonable target of 176.

Beer claimed 3-23 and Yardy 2-23.

Somerset were eventually restricted to 170 -8, with Jim Allenby marking his T20 debut for the club with 79, including seven fours and three sixes.

Earlier, Luke Wright (49), Mahela Jayawardene (36) and Chris Jordan (37) helped Sussex to a competitive 175-6, while another spinner, Max Waller, conceded only 20 from four overs.
