Alaves' push for Champions League football gathered more pace on Saturday after a 3-1 win away at Huesca.
The win leaves Alaves just one point off Getafe who occupy the fourth Champions League spot in LaLiga Santander before their tough trip to Valencia on Sunday.
The visitors got off to a flyer when VAR deemed Mantovani's handball inside the area deliberate, and Calleri made no mistake from the spot.
The joy was short lived, however, as Huesca were back on level terms just three minutes later, also from the spot, as Avila conveted.
It was a scrappy affair, one that required the Champions League hopefuls to outfight rather outplay their opposition and eventually they got their reward.
A long throw from Jonny was flicked on by Maripan and Guidetti was on hand to tap in for 2-1 with ten minutes remaining.
The game was sealed five minutes later as Wakaso set up Calleri who finished expertly to keep Alaves' dream alive.
