Watford defender Jamal Lewis says they targeted Saturday's game against struggling Rotherham as a potential "turning point" in their bid to still make the Championship play-offs.
The Hornets' 1-0 win over the bottom-of-the table Millers ended a run of three league defeats in a row.
Victory moved them up to 11th place, seven points off the top six with 13 matches to go.
"It was always going to need a gritty performance," Lewis, 26, said.
"To come away with a win away from home and a good display is always sweet."
The win, sealed by an excellent strike from Yaser Asprilla just before the hour, was Watford's first in six league games since they won at QPR in mid-January.
