Alfonso Thomas: Commentary of Somerset seamer's four in four balls

Listen to BBC commentary of Somerset bowler Alfonso Thomas taking four wickets in four balls against Sussex at Taunton.

Seamer Thomas bowled James Anyon, trapped Rory Hamilton-Brown lbw and had Ed Joyce caught behind for a hat-trick.

He then bowled Matt Machan with the first delivery of his next over after Peter Trego dismissed Chris Nash.
