Harrington plans to pump up the volume in 2013

Pádraig Harrington shot his best score in nine rounds on the Greg Norman Earth Course yesterday but is still a shot behind Rory McIlroy.

World No 1 McIlroy posted a six-under-par 66 on the opening day of the season-ending DP World Tour Championship Dubai to trail Luke Donald by a shot.

Harrington’s 67, however, raised most eyebrows but the triple Major winner has already switched his attention to his possible first event of 2013 — a first appearance in the Waste Management Phoenix Open.
