Pompey go in search of their first victory of 2018 when they travel to Rotherham this weekend.
But it is the hosts – who are one place behind the Blues in the table – who are 13/10 favourites with Sky Bet to come out on top.
Pompey won 3-2 on their last visit to Rotherham back in 2003 and a repeat of that scenario is available at 40/1.
Punters can also put money on the Blues winning in a contest that sees both sides finding the net, which carries odds of 5/1.
