Watford have wasted a number of opportunities against Huddersfield Town this afternoon but took the lead just before the break from the penalty spot.
Troy Deeney was involved throughout and smashed over from a tight angle after rounding Town keeper Alex Smithies early on.
Huddersfield stayed compact in defence and looked a threat on the break through Jermaine Beckford and James Vaughan.
Sean Scannell fired wide from range as the visitors grew in confidence before the break at Vicarage Road.
Gianfranco Zola's side worked the ball forward in the closing stages and Deeney hit the bar just before the break.
Deeney finally beat Smithies in stoppage time from the penalty spot, coolly slotting home for his 11th goal of the season to put the Hornets ahead.
