Goals by Clark Keltie and Tommy Wright gave Darlington victory at Brentford.
Keltie stroked home from the penalty spot after Wright was brought down in the box by John Mackie.
Wright doubled the lead in the 37th minute when he rose highest in the box to head home a half-cleared ball from almost under the bar.
Brentford came back into it after the break as Sammy Moore forced a fine save from David Stockdale, who also denied Lee Thorpe with a double stop late on.
