PSV Eindhoven kept the heat on second-placed Feyenoord with a crushing home victory over ADO Den Haag tonight.
The home side were already leading 2-0 through goals from Jeremain Lens and Ola Toivonen when the teams were forced to leave the Philips Stadion pitch soon after half-time due to heavy rain.
The players returned around 15 minutes later, and PSV soon set about increasing their lead with Toivonen making it 3-0 in the 62nd minute before Zakaria Labyad added a fourth three minutes later. Dries Mertens completed the scoring late on before ADO saw Kevin Visser sent off.
PSV's victory keeps them one point behind Feyenoord, who beat Heracles Almelo 4-1 tonight.
PSV were quickly on the front foot in their final home league game of the season with captain Toivonen sending a 10th-minute header just off target.
Toivonen saw two further efforts go just wide before Lens opened the scoring from close range in the 22nd minute after getting the better of ADO defender Tjaronn Chery.
Toivonen finally got his radar working in the 38th minute to make it 2-0, the Sweden international heading in Atiba Hutchinson's right-wing cross.
The hosts continued to dominate and almost made it 3-0 60 seconds later when Mertens' shot hit the top of the far post, while visiting goalkeeper Gino Coutinho was called on to deny Kevin Strootman just before the break.
The half-time interval and the weather-enforced delay soon after the restart could have slowed PSV's momentum, but that was not the case as they quickly set about increasing their lead in a one-side encounter.
Coutinho kept out two efforts from Georgino Wijnaldum and another from Labyad before PSV added a third when the unmarked Toivonen slotted in a Lens pass.
Labyad also enjoyed plenty of freedom to make it 4-0 soon after with a finish into the far top corner.
PSV had not finished there though, and they added a fifth in the 88th minute with a low effort from Mertens before a miserable night for ADO was made complete in the last minute when Visser was dismissed for a bad foul.
