Damien McCrory's Portsmouth debut ended in victory as the Burton Albion loanee's new side won 2-0 at AFC Wimbledon on Saturday.
McCrory - who is on loan at Fratton Park until January having joined late on deadline-day - started as Pompey secured their first League One win since the opening day, with Brett Pitman and Conor Chaplin grabbing the goals at Kingsmeadow - a ground at which Albion had tasted defeat in pre-season.
The result moves Portsmouth up to 14th in the table after six outings. That is eight places adrift of Oxford United, who beat Gillingham 3-0 on ex-Brewers skipper John Mousinho's debut for the U's.
In League Two, Marcus Harness was once again on the losing side as his Port Vale team stayed bottom of the EFL after a 1-0 loss at 10-man Coventry City.
Jodi Jones scored the winner for the Sky Blues - for whom former Albion forward Stuart Beavon came off the bench - with Harness' late effort well saved by Lee Burge to deny Vale a point.
Ben Fox's Solihull Moors debut ended in a 1-0 defeat at home to Macclesfield Town, although the Burton midfielder - who has impressed this season in the Carabao Cup for Nigel Clough's men - was named man of the match by the Moors' fans on social media.
A division below in National League North, Marcus Dinanga played 65 minutes as AFC Telford were thrashed 5-1 on home soil by Harrogate Town.
Dinanga's strike partner Anthony Dwyer got the Bucks' only goal as they suffered their fifth successive home loss.
Jayden Cotterill and academy goalkeeper Callum Hawkins both started in Matlock Town's 2-1 defeat to Whitby Town.
Cotterill was substituted at half-time, while Hawkins - who featured for the Brewers in pre-season and will gain valuable senior football experience at Causeway Lane - will have been disappointed by the Whitby opener, after Kieran Weledji's shot slipped under him.
Ryan Delaney's successful loan spell at Cork City continues, meanwhile, with John Caulfield's men taking their place in the Irish Daily Mail Cup semi-finals courtesy of a 4-1 victory at Longford Town.
Delaney again started in defence and played the full 90 minutes.
