Brentford hit the woodwork twice, but still left Somerset empty handed this afternoon, after two second half goals for the home side condemned Wally Downes' men to their first pre-season defeat.
The Bees started the brighter and Kevin O'Connor came closest to breaking the deadlock after 20 minutes, when Stephen Hunt and trialist, Gary McPhee, combined well to set up the Republic of Ireland U23 international, whose shot cannoned off the foot of the right hand post and away to safety.
At the other end, Yeovil Town came close just before half time, Abdel el Khoti's left-foot effort being brilliantly tipped away for a corner by Brentford keeper, Paul Smith.
The home side continued to press early in the second half and took the lead courtesy of a 35 yard looping strike from Kevin Gall, which completely bemused Smith and sailed into his net after 49 minutes.
Thereafter a spate of substitutions from both sides ensued, before the west countrymen wrapped the game up with ten minutes remaining, the exceptionally tall, Hugo Rodriges firing home from close range.
There was still time for Eddie Hutchinson to rattle the Glovers' cross bar, and Hunt to have an effort cleared off the line, but the visitors were to be denied a consolation.
So a disappointing reversal for the Bees in front of a crowd of (1, 936) at Huish Park, but a useful workout nevertheless, and a first appearance as a second half substitute for Scott McDonald, a player who spent some time at Southampton last season.
Smith (P), Dobson (Allen-Page, 65), Frampton (Fieldwick, 65), Sonko, Somner, Smith (J) (Tabb, 53), Hutchinson, McPhee (Peters, 57), Evans (Hunt, 17), Traynor and O'Connor (McDonald, 57).
Att: 1, 936
