Putting woes frustrate Harrington

With the annual New Orleans Jazz Festival in full swing, Pádraig Harrington struggled to find the right key with a flat performance in the Zurich Classic.

Harrington went into the event with a new putting set-up and while he stuck with it for four rounds, it hardly proved inspirational in ending with a one under par tally to finish well down the board.

The triple major winner fired a roller-coaster final round 74 in very hot and humid conditions of the TPC Louisiana course.
