AMSTERDAM, May 12 (Reuters) - Dusan Tadic scored twice as Ajax Amsterdam all but claimed the Dutch league title with a 4-1 victory over Utrecht on Sunday as championship rivals PSV Eindhoven slipped to a surprise 1-0 loss at AZ Alkmaar.
Ajax will go into the final round of fixtures on Wednesday with a three-point lead over PSV and 14 goals to the good on goal-difference as they travel to second-bottom De Graafschap. PSV are home to seventh-placed Heracles.
Klaas-Jan Huntelaar and Donny van de Beek also netted for Ajax as they put behind them the disappointment of their stoppage-time exit from the Champions League at the hands of Tottenham Hotspur this week.
Ajax will extend their record of Dutch title wins to 34 in a season in which they have scored 115 goals in their 33 league games and also claimed the Dutch Cup under manager Erik ten Hag. (Reporting By Nick Said Editing by Toby Davis)
