MARANA, Ariz. -- Through 11 holes, Graeme McDowell was playing steady while Padraig Harrington was missing some short putts. Consequently, the fifth-seeded McDowell was 3 up.
But McDowell then lost the next three holes, two with bogeys, to square the match. The battled between the Northern Irishman and the Irishman remained tight for the rest of the way until Harrington found trouble late to lose two of the final three holes.
McDowell said a key hole was the 15th when he followed Harrington's birdie with one of his own to keep the match squared.
"That kind of got me buzzing," McDowell said, "and I made some nice swings coming in."
McDowell advances to play Alexander Noren in the second round of the Jones bracket.
