Watford's winless run since the start of the Premier League campaign stretched to 10 games when they played out a 0-0 draw against Bournemouth at Vicarage Road on Saturday but they had goalkeeper Ben Foster to thank for a rare clean sheet.
Foster kept Watford in the game with a string of saves as Bournemouth tested him with shots from distance. He was forced to dive low to his right twice to keep out Diego Rico's stinging shot and a well-placed curler from Philip Billing.
The visitors' best chance of the first half came on the stroke of halftime when a quick counter-attack released Callum Wilson on the right and his cross to the far post was met by Arnaut Groeneveld, whose effort was kept out by a diving Foster.
It was Bournemouth keeper Aaron Ramsdale's turn to provide the highlights in the second half, first denying Gerard Deulofeu at his near post and then flying low to his left to palm away a low drive from Hughes in the 75th minute.
The result leaves Quique Sanchez Flores's Watford bottom of the standings with five points while Bournemouth, who were held to a second consecutive 0-0 draw, are eighth with 13 points.
