PSV Eindhoven moved to the top of the Eredivisie with the only 100% record in the Dutch top flight after beating AZ Alkmaar 3-1 on Sunday.
Marcus Berg scored twice for the hosts, either side of a Erik Falkenburg equaliser, with substitute Ibrahim Afellay adding a late third for PSV.
Fred Rutten's men now hold a two-point lead over Ajax, who overcame Roda JC on Saturday. Two goals by Mounir El Hamdaoui and a strike by Luis Suarez saw Martin Jol's side temporarily move to the top of the Eredivisie with a 3-0 win.
El Hamdaoui opened the scoring 10 minutes before half-time with Suarez doubling the lead before the former got his second with 18 minutes to go.
FC Utrecht are a further point behind PSV, after running out 3-0 winners against Willem II.
The outcome could have been very different however if Andreas Lasnik had not missed a 20th-minute penalty for Willem II, with Utrecht rubbing salt in the wound by converting a spot-kick of their own two minutes later through Ricky van Wolfswinkel.
The game was over as a contest by the 33rd minute as Dries Mertens and a Van Wolfswinkel header killed off the Tilburg club, who have lost all three of their league matches so far. Both teams ended with 10 men, Utrecht's Alje Schut and Willem II's Frank Demouge both seeing red.
Heracles had to settle for a point against Feyenoord after a 1-1 draw. Mark Looms scored for the home side after 14 minutes, but Georgino Wijnaldum equalised 20 minutes from time to leave both sides on four points after three games.
Torrential rain held up proceedings for 20 minutes at VVV-Venlo's De Koel stadium, but it could not stop ADO Den Haag registering their first win of the season.
ADO were 2-1 up, courtesy of two goals from Dmitri Bulykin on his debut sandwiching Achmed Ahahaoui's reply, when referee Bas Nijhuis took the players off the pitch in the 67th minute because of thunder storms.
When play did finally resume, the fans were rewarded with a grandstand finish as Wesley Verhoek extended ADO's advantage in the 89th minute and Ruud Boymans offered an immediate, but ultimately futile, response.
On Saturday, Luuk de Jong scored twice as three second-half goals propelled defending champions FC Twente to a convincing 3-0 victory at Vitesse Arnhem.
Marc Janko put the visitors ahead after 58 minutes and De Jong struck after 66 and 90 minutes to complete the victory.
It was Twente's first win of the season as they remained unbeaten from three games, while Vitesse fell to a second loss of the campaign.
FC Groningen held off a fightback from 10-man De Graafschap to clinch their first win of the campaign 2-1.
Andreas Granqvist put Groningen in front with a penalty after 17 minutes, following a professional foul on Tim Matavz by Jan-Paul Saeijs, and the lead increased to 2-0 just after the half-hour mark when Thomas Enevoldsen netted.
But De Graafschap slashed the lead when Rydell Poepon scored from close range midway through the second half, and they briefly threatened an equaliser, but the home side held on.
Bas Dost's first two goals for Heerenveen helped them claim their maiden win of the season, 3-1 over hapless NAC Breda, who remained without a point after a third successive defeat.
NAC got off to the ideal start as Matthew Amoah put them ahead in the first minute, but it was downhill from there as Dost levelled 25 minutes in.
An own goal from Kees Luijckx on the hour mark put Heerenveen ahead before Dost grabbed his second 13 minutes from time.
