Own-goal agony for the Millers ... on-the-whistle report: Swansea City 1 Rotherham United 0

The Rotherham United midfielder lay down disconsolately on the turf after putting his team behind with an own goal.

The Millers had been keeping Swansea City at bay with some degree of comfort and were looking good for a rare away point in the Championship.

Then Rinomhota headed a 75th-minute Liam Walsh corner into the net to gift the Swans the spoils.

Rotherham, already relegated but putting up decent resistance on their travels for the second match in succession, remain on 23 points .

They have three games left in which to earn the extra one they need to avoid equalling the division's record low total they set themselves seven years ago.

Viktor Johansson was called into action in the eighth minute, the goalkeeper getting down quickly to keep out a Liam Cullen shot as the home side started strongly.

The Millers were being starved of the ball by possession-based opposition yet they were next to have an effort on goal.

Swansea old boy Sam Clucas, a £16.5 million City signing seven years ago, tried his luck from the edge of the area and his miscued volley brought jeers from home fans who had been directing a smattering of boos towards him since kick-off.

On a wet, miserable day in South Wales, the visitors were conceding a number of corners but managing to keep their goal intact.

Johansson parried a speculative effort by Jay Fulton from a tight angle as the half-hour mark came and went with the Swans struggling to create any real openings.

Rotherham continued to defend resolutely against opponents who started the contest in 15th spot and had no play-off hopes or relegation concerns.

As the interval approached, Johansson was up to the challenge when Jamie Paterson dispossessed Cameron Humphreys and skipped through on goal from 50 yards out.

The save required to keep out a fierce Ronald effort soon afterwards was the keeper's best moment of the half.

The Millers had made no changes to the side that had started Wednesday night's match at West Bromwich Albion.

With the treatment room as crowded as ever, there were again two spare places on the bench as the same seven substitutes were named.

Players' voices echoed around a near-silent stadium in the early stages of the second half of a game with a real end-of-season feel.

Rotherham continued to shut down Swansea in the final third and restricted the home side to a tame shot from Ronald that was easily dealt with by Johansson.

At the other end, Rinomhota was off target from distance for the Millers who had seen Clucas leave the fray through injury.

Disaster struck when Rinomhota inadvertently beat Johansson, doing something Swansea had looked unlikely to achieve themselves.

Teammates pulled him to his feet and Rotherham battled to the final whistle.

Tom Eaves flashed a stoppage-time header just wide, but the Millers had lacked an attacking edge all afternoon and Rinomhota’s contribution at the wrong end proved to be decisive.
