VIEW FROM THE DRESSING ROOM
Somerset director of cricket Brian Rose told BBC Somerset:
"With the cricket we've played over the last three or four years, we breezed in to quarter-finals and semi-finals.
"But we've done it the hardest way. We started well but faltered, before coming back to play a very professional game.
"I think if Worcestershire had got another 20 or 30 it would have been a different story.
"But we've learnt our lesson from one or two innings we've had in previous games and I thought we did very well."
