Ryan Seager made it two goals from two League One games for MK Dons as they recorded a 2-0 victory over AFC Wimbledon on Friday night.
Seager played 71 minutes of the derby clash and broke the deadlock on just seven minutes when he got a telling touch on Osman Sow’s low cross from the left wing.
Gboly Ariyibi doubled the advantage on 27 minutes when he showed composure after a scramble in the box, before Lee Nicholls saved a second-half Lyle Taylor penalty to allay any lingering fears of a comeback for the hosts.
Elsewhere, Harrison Reed played the duration of Norwich City’s 0-0 draw with Bristol City in the Championship.
Sam Gallagher also featured for loan club Birmingham City, playing 63 minutes of a 1-1 draw as the Blues earned caretaker manager Lee Carsley a precious point against Derby.
Lukas Jutkiewicz was introduced in place of Gallagher at Pride Park, who scored just one minute after being introduced with a glancing header.
But the hosts responded three minutes later when a substitute of their own made an instant impact, as Sam Winnall finished Richard Keogh’s header across the box.
In League Two, Olufela Olomola recovered from an injury to partner Francios Zoko and play 73 minutes of Yeovil Town’s 1-1 draw with Port Vale at Huish Park.
North of the border, Harry Lewis helped Dundee United to a 2-1 win over Greenock Morton in the Scottish Championship, with goals from James Keatings and Scott McDonald.
Jordy Clasie was an unused substitute as Club Brugge recorded a crucial 2-1 away victory to maintain their lead in the Belgian top-flight against second-placed Charleroi.
