Jon Taylor scored the only goal of the game as Rotherham ended their long away-day drought with a 1-0 win at Portsmouth.
Rotherham hadn't won any of their last 27 away league games, but Taylor, 25, bagged his first goal of the season late on in the first half to stun the Pompey crowd into silence and give the Millers their second league win this campaign.
It took the away side just two minutes to register their first shot when Taylor struck his free-kick just wide of the post from a dangerous position.
Pompey followed up with a chance of their own minutes later after captain Brett Pitman weaved past Will Vaulks before striking his effort over the bar from outside the area.
However, Rotherham took the lead in the 36th minute when Ryan Williams slipped a pass for Taylor to run onto before he lashed his strike past goalkeeper Luke McGee at the near post.
The home side's best opportunity came via Jamal Lowe when the winger was gifted a free header on the stroke of half-time but he could not direct it on target.
