And Paul Cook’s side are 17/20 favourites with Sky Bet to secure a fourth successive victory when they visit Broadhall Way.
The hosts – who are also in the battle for a place in the top three – can be backed at 16/5, with the draw at 12/5.
Boro triumphed 2-1 when the sides met at Fratton Park earlier in the campaign and you can get odds of 15/2 on that scoreline being reversed.
Punters might also want to take a look at the 7/4 on offer for the Blues leading at both half-time and full-time.
Conor Chaplin and Gary Roberts are the joint 5/1 favourites to net the opener in Hertfordshire on Saturday.
Elsewhere in the first goalscorer market, Carl Baker, Gareth Evans and Matt Clarke are available at 15/2, 11/1 and 25/1 respectively.
