MORECAMBE went down to their third defeat in four games with this 3-0 defeat at the County Ground.
Morecambe went a goal down on 26 minutes when on loan Birmigham striker Jake Jervis nipped in between two Shrimps' defenders to head past Barry Roche from eight yards out.
Jim Bentley's side hit back and Danny Carlton was denied an equaliser by a superb save from Wes Foderingham who got down low to his right to claw the ball into the path of Andy Fleming who could only find the side netting with his follow up.
The Shrimps went close again when a Chris McCready
header flated the wrong side of the right hand post but they were undone for a second time on the strike of half time.
Matt Ritchie's cross was met by Raffaele De Vita at the far post as he made no mistake from six yards out.
Morecambe looked to fight back in the second half with Foderingham again producing a superb save to tip away Phil Jevons's header.
But the Shrimps' hopes of a comeback were dashed as the home side added a third on 76 minutes when Ritchie again provided the telling ball to feed substitute Ronan Murray who fired past Roche from 12 yards.
Boss Jim Bentley made three changes to the side that drew 0-0 against Oxford last week.
Both left sided players Laurence Wilson and Kevin Ellison are injured which means recalls for Andy Parrish and Andy Fleming while Phil Jevons drops to the bench in place of Danny Carlton who will start as a lone striker.
Swindon include former Shrimp youngster Jonathan Smith in their line up.
