Rory McIlroy has eased his worries of potentially missing the cut with an eagle at the 13th to move to level par.

Padraig Harrington and Shane Lowry's tournaments are over, having finished day two on 5-over and 3-over respectively.

Darren Clarke and Graeme McDowell will squeak into the weekend on 1-over.

The runaway leader is Jordan Spieth, who set a 36 hole record at Augusta to end the day on 14-under par, five clear of Charley Hoffman.
