Sean Raggett joined Rotherham on loan from Norwich in July
Sean Raggett’s first-half header gave Rotherham United a hard-fought victory over Millwall in their Championship encounter at the New York Stadium.
The defender, on loan from Norwich, glanced in Will Vaulks’ cross and that was enough to earn the Millers their second league win of the season.
Michael Smith almost made it 2-0 following clever link-up play with Kyle Vassell in the second half, but his strike was well saved by Jordan Archer.
Millwall’s best opportunities saw Jake Cooper’s header and Tom Elliott’s shot kept out smartly by Rotherham goalkeeper Marek Rodek as they piled on pressure without reward after the break.
Relive Rotherham’s victory over Millwall as it happened
Neil Harris may well be ruing keeping club-record signing Tom Bradshaw on the bench, and not bringing the Wales striker on until midway through the second half.
The Lions lacked a cutting edge throughout the 90 minutes, although the wet and windy conditions in south Yorkshire made flowing football difficult for both sides.
Bradshaw did go close to netting an equaliser on debut but his header flew over and Jed Wallace flashed a long-range effort past the post, as Rotherham defended stoutly.
The Millers now face a trip to Premier League side Everton in round two of the Carabao Cup on Wednesday, while Millwall host Plymouth Argyle.
Rotherham manager Paul Warne:
“I thought it was a real football game in Yorkshire. The weather has changed and it feels like the football season is finally here.
“The lads have done everything for us to get the win against a really good side. For us to get a win and not to lose two home games in a row was crucial.”
Millwall boss Neil Harris:
“I am frustrated, Rotherham did nowhere near enough to win the game against us. That’s twice in five days that we have thrown points away.
“Rotherham got their noses in front and had something to cling to and it was very difficult to break them down. Fair play to them. But that is three cheap goals in two games.”
