Kemar Roofe's struck a second-half stunner as Oxford United moved up to fourth in League Two with a 1-0 win at Bristol Rovers.

Roofe found the top corner with a right-footed half-volley in the 62nd minute of a game that saw both sides reduced to 10 men.

Rovers' Ollie Clarke was shown a straight red card for a 17th-minute aerial challenge on Danny Rose, while Oxford's Liam Sercombe was given a second yellow for bringing down Matt Taylor on 58 minutes.

Neither goalkeeper saw much action in the first half, though Ryan Taylor should have done better for the visitors when heading over from George Baldock's 36th-minute cross.

Roofe finally broke the deadlock in style, leaving Aaron Chapman clutching at air, but there was concern for Oxford when he had to be substituted on 75 minutes clutching his arm.

Jermaine Easter volleyed straight at Sam Slocombe on 66 minutes before Tom Parkes headed into the arms of the Oxford keeper 12 minutes from time as the hosts pushed for an equaliser.

Slocombe produced the best save of the game at full stretch to keep out Chris Lines' 86th-minute free-kick but Roofe's stunner proved decisive.
