Darren Clarke wants to end with under-par final round

Darren Clarke says he wants to end the Masters by shooting an under-par round on Sunday after posting a one-over 73 on Saturday.

"My front nine was 'so-so', my back nine better. A 73 was not bad but it should have been better," commented the 2011 Open champion.

Clarke lies five over for the tournament going into his final round.
