Pompey make their longest League One journey of the season on Saturday when they visit Sunderland.
It is the hosts who are the 13/10 favourites with Sky Bet to secure victory the Stadium of Light.
Kenny Jackett’s troops can be backed at 2/1 to take the points back to the south coast, with the draw available at the same price.
You can also take advantage of a Sky Bet boost, with the Blues coming out on top in a contest where both sides find the target moving from 6/1 to 7/1.
It finished 1-1 in last campaign’s corresponding fixture and a repeat of that scenario carries odds of 9/2.
More optimistic punters might prefer to back Pompey success, with 1-0 on offer at 7/1 and 2-1 at 11/1.
But if you believe they will have to work hard, then back them to recover from an interval deficit before triumphing at 40/1.
Craig MacGillivray will be aiming to keep a third successive clean sheet, with odds of 21/10 on a shut-out.
John Marquis is the 9/2 favourite to net the opener, ahead of Ronan Curtis at 6/1 and Ellis Harrison at 11/2.
Elsewhere in the first goalscorer market, Brett Pitman, Ben Close and Paul Downing are available at 13/2, 11/1 and 50/1 respectively.
