Pompey continue their search for a first victory of 2018 when they host Doncaster this weekend.
And Kenny Jackett’s side are the 11/10 favourites with Sky Bet to secure all three points at Fratton Park.
The visitors – who are five points behind the Blues in 14th position – can be backed at 11/4, with the draw at 11/5.
Pompey were beaten 2-1 when the sides met earlier in the season and you can find odds of 2/1 on them winning by that scoreline this time.
Punters might instead prefer to put their money on a 1-0 victory at 5/1 or even a 3-0 triumph at 18/1.
And if you believe that the hosts will enjoy a comfortable afternoon by leading at both half and full-time, that is on offer at 9/4.
Brett Pitman will hope to be restored to the starting line-up against Rovers and is 7/2 favourite to net the opener.
Elsewhere in the first goalscorer market, Oli Hawkins, Gareth Evans and Anton Walkes are available at 11/2, 11/1 and 28/1 respectively.
