It was a quiet first half, which looked to be heading towards a goal less draw going into half time. Deep into stoppage time Swindon took the lead after a long throw from Sean Morrison who found Cuthbert who header found the back of the net to make it 1-0.
Milton Keynes then scored two quick goals to make it 2-1 after 71 and 72 minutes. Both were scored by Baldock, then first following a corner, and the second with a header.
With a minute of normal time remaining Swindon were reduced to ten men after David Prutton was sent off after getting a second yellow card for a foul.
The defeat leaves Swindon with just 2 points, and in 20th place after the opening 4 league games. Swindon now take a break from the league as they travel to Southampton on Tuesday night to play in the Johnstone's Paint Trophy.
