Doncaster Rovers’ unbeaten start to the season came to an end at AFC Wimbledon.
Rovers manager Darren Ferguson made one change to his starting line-up, with Alfie May in the first XI at the expense of Liam Mandeville.
The home side started brightly, but the opening 45 minutes saw few chances for either side.
Rovers' best opportunities came from free-kicks, with Ben Whiteman and Danny Andrew both firing efforts over.
Whiteman’s attempt was looking to place the ball in the top-left corner, while Andrew went for power: both times saw the ball end up going over the bar.
Wimbledon’s best chance came in the closing stage of the match, with Lyle Taylor going close after good work down the left from Andy Barchan - the tricky winger providing the home side’s main threat.
It was goalless at the break, and the match really stepped up a gear after the restart. George Long had to be switched on to scramble away an Andrew free-kick three minutes in, setting the tone for a second period that was far more open than the first.
Rovers will feel they should have taken the lead after 55 minutes after a great counter down the left. Tommy Rowe’s pass just was not hit hard enough to find Alfie May, and the home side were let off.
And Rovers were made to pay in some style. Two minutes later Appiah turned in the area and smashed the ball past Ian Lawlor.
And a further two minutes down the line they made it 2-0. Barcham was allowed too much space to run, and stuck a great effort into the bottom-right corner.
That took the sting out of the game, but Ferguson reached with an immediate change: sending on Liam Mandeville and Rodney Kongolo for James Coppinger and Niall Mason.
Mandeville immediately curled an effort over, and Ben Whiteman just could not get his foot through an effort from the edge of the area.
Andy Williams came off the bench, replacing John Marquis, for the final 20 minutes. He fired over, and curled an effort just wide, as he provided the main attacking threat in the closing stages.
The home side saw out the win and almost got a third when Callum Kennedy saw a great free-kick come back off the woodwork in stoppage time.
