The outstanding James Masters (left) challenges Ger Cavlan

Tyrone led early on but two points from the superb James Masters helped Cork lead 0-6 to 0-4 at half-time.

The dismissal of off-form Owen Mulligan after he appeared to strike Michael Shiels then didn't help Tyrone.

The Red Hands completely capitulated in the closing stages as Cork knocked over a succession of spectacular points.

James Masters finished with six points for Cork while Kevin O'Sullivan hit five scores.

Amazingly, 14 of Cork's 15 scores came from play as their strong running completely unhinged the leaden Tyrone outfit.

Tyrone went into the game as strong favourites after their opening wins over Dublin and Fermanagh.

In contrast, Cork had been beaten by Donegal and Kerry and most pundits were expecting Mickey Harte's side to maintain their 100 per cent record in the division.

However from an early stage, it was clear that Tyrone were struggling.

The Cork half-backs were dominating the Tyrone attackers with man-of-the-match Ger Spillane and Anthony Lynch in especially dominant form.

Still, Tyrone kept in touch during the first half with captain for the night Stephen O'Neill knocking over a couple of fine points.

Cork led 0-6 to 0-4 at the interval and Masters and O'Neill swapped points early in in the second half which maintained the home team's two-point lead.

However, O'Neill then missed a straight forward free for Tyrone and things went from bad to worse when Mulligan picked up his straight red card which is likely to run him out from league action for at least a month.

Two more points from Masters and Kevin O'Sullivan's third score extended Cork's lead to 0-10 to 0-5 by the 59th minute.

Instead of a Tyrone comeback, things deteriorated still further as Masters, Donnacha O'Connor, O'Sullivan and Kevin McMahon hit four scores in as many minutes to extend Cork's lead to 0-14 to 0-5.

Raymond Mulgrew's 67th-minute point was Tyrone's first score in half an hour and while Ryan Mellon added another Red Hand point, Kevin O'Sullivan had the final scoring say in injury-time.
