After cruising past Mjallby on the opening weekend, the favourites for the 2026 title were given a reality check by Sirius last weekend. Orgryte, meanwhile, had drawn with Malmo and beaten Mjallby on a dream start back in the top flight.
However, facing a Hammarby side desperate to prove their worth was just the recipe to turn the dream into a nightmare. It began 11 minutes in, when Markus Karlsson squared for Noah Persson, who arrowed the ball into the top corner from 25 yards.
Persson turned provider seven minutes later, when his corner was cushioned in on the volley at the back post by Nahir Besara, before Paulos Abraham got in on the act midway through the first half by tapping in after Victor Lind caused havoc.
Orgryte thought they had a glimmer of hope 10 minutes later when Christoffer Styffe headed in a rebound from a free-kick, but the lead was back to three goals a minute later, as this time Lind finished the move himself with a powerful right-foot shot across the goalkeeper - his first for his new club.
Bajen had to wait until 12 minutes into the second half for their fifth, but it was worth the wait, as Besara found Montader Madjed, who cut in from the right and curled a beauty over Hampus Gustafsson.
The final 20 minutes belonged to Nikola Vasic - 10 minutes after coming on, he latched onto a precise Frank Adjei through ball and stabbed home. Then, Gustafsson's afternoon got worse when he was tackled by Lind, who squared to Vasic for the easy finish.
And five minutes from time, a low centre from the left wing from Lind allowed Vasic to complete his hat-trick from close range, securing Hammarby the biggest win in Allsvenskan since 2008. Even at this early stage, it's not enough for Bajen to sit in the top three!
Top of the table with nine points from three games are the impressive Sirius, who sealed the points with a strong first-half display at home to another of the new boys, Vasteras.
The deadlock was broken just eight minutes in after Oscar Krusnell was brought down in the box by Simon Gefvert after a neat one-two with Robbie Ure, and Isak Bjerkebo stroked home the penalty.
Bjerkebo made it a brace from the spot just after the half-hour mark after Frederic Nsabiyumva was guilty of blocking a Matthias Nartey shot with his hand, and with a carbon copy of his first spot-kick, Bjerkebo sent Elis Jager the wrong way.
Vasteras almost got themselves back into it when they hit the post, but in first-half stoppage time the match was all but beyond them, as a deep cross caused pinball in their area before Tobias Anker forced the ball over the line.
The visitors did give themselves a glimmer of hope eight minutes into the second half when Nsabiyumva atoned for his earlier error by heading in Marcus Baggesen's corner, but just nine minutes later it was game over, when Krusnell's knock down at a free-kick was turned in by Henrik Castegren.
Blasvart are guaranteed to be two points clear come the end of the round, while Vasteras, like Orgryte, are on four points having seen their unbeaten return come to a resounding end.
Following a disastrous start, Mjallby have their first league win under Karl Marius Aksum, as they too got the job done in the first half to see off Brommapojkarna.
Five minutes in, nerves around Strandvallen were settled when Ludwig Thorell found space inside the box and curled the ball into the bottom corner, and if that made MAIF feel like their old selves, they proved it in the 28th minute when Elliot Stroud's low cross was turned in by Jacob Bergstrom.
And the win was all but wrapped up five minutes later, when Jesper Gustavsson found Abdoulie Manneh at the edge of the area, and he fired a cracker in off the post. That was enough to take the champions off the foot of the table, overtaking BP whose run of successive draws is over.
Finally on Saturday, Halmstad and Goteborg picked up their first point each of the new campaign in a 1-1 draw.
Just after the hour mark, Ludvig Arvidsson's through ball found Omar Faraj, who guided it in at the near post to give Halmstad the lead, but two minutes later, Goteborg spared their blushes when Tobias Heintz tapped in a header across goal by Saidou Alioum.
That was the Gothenburg side's first goal of the season, but it wasn't enough to prevent their worst start to the season since 2023, when they narrowly avoided relegation. Halmstad are in 13th, above the Angels on goal difference.
