The Millers looked destined for relegation following seven successive games without victory at the end of February, a run which also included five defeats.
But former Whites head coach Neil Warnock has transformed the Millers’ fortunes and their improvement has not gone unnoticed by the layers.
Rotherham are as short as 6-5 to beat Leeds with Paddy Power, with the Millers a best-priced 24-17 with Marathon Bet.
The Whites, who will be looking to bounce back from the awful 4-1 loss at home to Huddersfield Town, are available at 23-10 with Marathon Bet, who incidentally offer the biggest price about Leeds being relegated.
Marathon Bet offer 250-1 about United going down whereas Rotherham are only a best-priced 7-2 to be relegated.
The fifth-bottom Millers are eight points behind 13th-placed United who have a game in hand but recent form has determined the weekend’s market.
A draw between the two can also be backed at 23-10.
With Rotherham firm favourites, it’s no surprise that the majority of the prominent names in the first scorer market play for the hosts.
Leon Best and Matt Derbyshire are both 13-2 shots with Danny Ward on offer at 7s. For Leeds, Chris Wood is also 13-2 with Mirco Antenucci and Souleymane Doukara both 7s.
No goalscorer - at 7s - is rated more likely than any other player netting first though Alex Mowatt may be worth a shout at 11s.
