FC Twente beat Ajax 1-0 on Sunday to maintain their place at the top of the Eredivisie.

Bryan Ruiz scored the only goal of the game two minutes after the restart to keep Twente two points clear of PSV Eindhoven.

Not the least of Twente's achievements was keeping quiet an Ajax attack which had managed 40 goals in 12 league games before this afternoon.

Ola Toivonen bagged four goals for PSV in a 5-1 win at ADO Den Haag but he had to share the limelight with referee Roelof Luinge.

The official harshly dismissed two ADO players and stopped play midway through the second half when he took exception to obscene chanting from the crowd.

By that stage PSV were 4-0 up, through a hat-trick from Toivonen and Otman Bakkal's strike, while ADO had seen Ricky van den Bergh and Lex Immers sent off.

When play finally resumed, Karim Soltani pulled one back for the nine-man hosts, before Toivonen completed his haul.

AZ Alkmaar needed a second-half equaliser from Brett Holman to earn a point against Feyenoord in a 1-1 draw. Feyenoord had taken a fifth-minute lead through Sekou Cisse.

FC Utrecht slumped to their first home defeat of the season as Heerenveen survived a late fightback to register a 3-2 win.

The visitors cruised into a 3-0 lead, two goals from Michal Papadopoulos adding to an early strike from Viktor Elm.

Utrecht hit back late on but efforts from Tim Cornelisse and Jacob Mulenga did not pave the way for a dramatic equaliser with Heerenveen clinging on to a win which moves them clear of the relegation zone.

In Sunday's early game, NAC Breda beat Willem II 4-0 with first-half goals from Kurt Elshot, Kees Kwakman, Matthew Amoah and Leonardo.

On Saturday, RKC Waalwijk claimed just their second win of the Eredivisie season despite being reduced to 10 men at NEC Nijmegen.

Derk Boerrigter put the visitors in front after 32 minutes of a hotly-contested match which saw eight players booked.

Hans Mulder was sent off for two bookable offences after 80 minutes but basement boys Waalwijk held on.

Vitesse Arnhem climbed away from the relegation zone with a welcome 2-0 victory over fellow strugglers VVV Venlo.

Dalibor Stevanovic put the home side in front after 38 minutes and Domingues Claudemir eventually sealed the win in injury time.

Boldiszar Bodor's superb second-half free-kick earned Roda JC a shock first win in six games against in-form Sparta Rotterdam and lifted them out of the drop zone.

Rydell Poepon's penalty had cancelled out Mads Junker's opener, but Roda regained the lead with 20 minutes to go and held on.

Slovenian striker Tim Matavz struck a late double to put the gloss on struggling Groningen's emphatic 4-1 success over in-form Heracles Almelo on Friday night.

Starting the evening second-bottom of the table, the home side were hit early when Bas Dost fired home in the 15th minute to give Europa League hopefuls Heracles the lead.

But the visitors, who had high hopes of maintaining the pressure on the division's top five, were quickly hauled back level when 18-year-old Leandro Bacuna netted his first goal of the season seven minutes later.

Groningen pushed ahead and went in front four minutes from the interval when Swedish defender Andreas Granqvist scored a rare goal from the penalty spot for a 2-1 lead.

The home side held firm in the face of Heracles pressure in the second period and made the game safe in the 71st minute through Matavz, who went on to double his tally eight minutes later.
