The veteran striker struck twice in Tuesday night’s 3-1 success over Danny Cowley’s side to kept alive slender hopes of avoiding relegation to League Two.
Pitman, of course, enjoyed a successful three years at Fratton Park, skippering the team to the Checkatrade Trophy in 2019 and netting 42 goals in 99 appearances.
Ultimately, a bitter fall-out with Kenny Jackett impacted on his appearances during last season’s final year of his contract, culminating in a summer exit as a free agent.
Nonetheless, following his two-goal haul on Tuesday, the 33-year-old insists he bears no animosity to the club or fans.
He told the Swindon Advertiser: ‘It’s always nice when you win and when you score.
‘I had a great time at Portsmouth and I really enjoyed it. It’s a great club with great fans, I really enjoyed my time there.
‘It didn’t finish great, but that was nothing to do with the club or the fans, so I’ve got nothing but good words to say about Portsmouth.
‘Tuesday wasn’t about me beating Portsmouth or being scoring against Portsmouth, it was about us winning.’
Pitman’s opener was a powerful angled finish from Jack Payne’s pass after a mistake from Charlie Daniels.
The striker then added a second on 61 minutes from the penalty spot after Daniels had needlessly fouled Tyler Smith.
It took the former Bournemouth man’s tally to 11 in 39 outings for the struggling Robins this term.
His one-year deal expires in the summer, although Swindon possess a club option for an additional 12 months.
