An excellent performance came out of the blue to send Vale back to 5th spot.
On loan Jay O'Shea hit the post with a well hit free kick, but later scored the winner on 53 minutes. He intercepted a pass to Justin Richards, flicking the ball up then volleying it home brilliantly.
4th place Rotherham were humbled by Vale's determined performance, and Vale should have won by 3 or 4.
Has Jim Gannon turned the corner? If this game is anything to go by, he has.
