Despite their first-half control, Wrexham were forced to dig deep during the closing stages as Oxford threw everything at them. The home side utilized long throws and set pieces in a desperate attempt to find an equaliser, but Parkinson's men held firm under intense pressure to secure the clean sheet.
"We showed two sides to our game," Parkinson added. "First half we had really good control in the game, we were patient and took care of the ball. The moment came and we had chances second half, but we knew Oxford would throw caution to the wind. They're fighting for their lives. Long throws, set pieces, and we defended as a team. Everyone did their job."
