A second-half strike proved enough to deliver struggling Huesca their first win of the league season.
For Alaves it amounts to their fifth defeat of the season and sees them sit in 14th, three points clear of the drop zone.
The hosts thought they had found a breakthrough in the 48th minute through Shinji Okazaki, only for it to be disallowed.
Come the 66th minute, however, there was nothing wrong with Javi Ontiveros‘ eventual winner.
