League One Stevenage secured a place in the second round of the Carabao Cup by beating Watford on penalties.
The tie was level at 1-1 after 90 minutes after Josh Marsh equalised for the hosts to cancel out Vakoun Bayo's opener.
And Nathan Thompson scored the winning penalty for Stevenage in the shootout.
Bayo gave Championship side Watford an early lead by prodding home after being found by Tom Dele-Bashiru's free-kick - the Ivorian's second goal in as many games.
Stevenage responded well and scored a deserved equaliser shortly before half-time.
Watford were unable to clear Jake Forster-Caskey's right-wing corner and Marsh controlled the ball before firing past keeper Ben Hamer with a clever bicycle kick.
