Scott Sinclair grabbed a hat-trick as Swansea City eased through to the next round by seeing off League One Peterborough at London Road.
Sinclair, who was signed for £500,000 from Chelsea in the summer and has now scored seven goals for Brendan Rogers' side put them ahead in the fifth minute after a mazy run. Peterborough soon hit back, the unmarked Craig Mackail-Smith tapping in Charlie Lee's cross.
Four minutes before half-time Sinclair latched on to a pass from David Cotterill to put the visitors back in front. Scott Dobbie's backheel put then put him through on goal 12 minutes from the end and the winger picked his spot from six yards. "Every game he plays, it looks like he is going to score," Rogers said.
