Atletico Madrid scored three goals in the opening 18 minutes as they romped to a 5-0 win at 10-man Las Palmas, which keeps them ahead of Sevilla in third place.
Diego Simeone's side, who face city rivals Real Madrid in the semifinals of the Champions League next week, made the perfect start at Estadio de Gran Canaria when Kevin Gameiro put them ahead inside two minutes as he swept in Saul Niguez's cross from the left.
It was soon 2-0 when midfielder Saul headed in from a corner after 17 minutes, with Gameiro adding a third almost immediately from the restart following a break down the right.
Las Palmas managed to regroup for the second half, but then saw midfielder Kevin-Prince Boateng sent off for a second caution on 65 minutes.
The hosts, though, managed to hold out until Atletico substitute Thomas Partey made it 4-0 in the 72nd minute.
Veteran forward Fernando Torres, who had replaced Gameiro just before the hour, completed the route with a close-range finish in stoppage time.
