Oxford with less than 35% of the ball in the second half comfortably held off a stronger Cambridge XV having led 15-3 at half time.
Oxford were more inventive and held their passes under pressure. Cambridge disrupted the Oxford scrum and the lineout but were all fingers and thumbs and should have scored three times in the second half.
Nonetheless, Oxford deserved their victory for a purple patch in the first half which saw them score two well taken tries.
