Charlie Wyke’s late winner against Millwall last time out might have ended Rotherham’s 15-match winless league run, but Plymouth perhaps had more to play for, with the Pilgrims now staring at the potential risk of falling into the relegation zone for the first time this season.
As the only two Championship sides this campaign to have faced over 600 shots, it was no surprise to see both have a go at one another, but the visitors eventually broke the deadlock 13 minutes from HT via Bali Mumba.
Morgan Whittaker floated a pinpoint cross to the left-back, who exquisitely controlled it before smashing past Viktor Johansson at the near post to put his side in the driver’s seat.
With their second-tier future hanging in the balance, Leam Richardson turned to his bench for inspiration with a triple substitution, but instead it was the visitors who continued to look more threatening.
Ryan Hardie forced a save from Johansson, while Ben Waine came close to doubling the visitors' lead on multiple occasions, even striking the post in the closing stages.
In truth, the second period was somewhat of a non-event as a dejected home crowd watched on in anguish as Plymouth secured a first win in seven league games, and earned a first league H2H double over the Millers since 1998/99.
Rotherham will compete in the third tier next season, a fate Plymouth will be desperate to avoid a similar fate, though it looks the relegation dogfight will go down to the wire.
