Substitute Alex Mowatt made an instant impact as Oxford United made it back-to-back wins with a 1-0 victory over Blackpool.
Mowatt came off the bench in the 78th minute and his first touch was to send over a free-kick that Jon Obika met with a glancing header for the winner - his seventh goal of the season.
But the result was harsh on the Seasiders, who were denied by four fine saves from keeper Simon Eastwood.
Oxford missed a golden opportunity in the 10th minute when Gino van Kessel selfishly went alone as he and strike partner Wes Thomas bore down on goal.
A simple square pass would have surely led to a goal, but Van Kessel thought he could score, only for keeper Christoffer Mafoumbi to dispossess him.
Eastwood tipped over Clark Robertson's left-foot drive and then blocked a volley from right-back Kelvin Mellor.
The U's keeper also saved well from Colin Daniel's shot, before pushing over Viv Solomon-Otabor's 20-yarder, and another fierce drive from Robertson.
