The Australian, who narrowly missed out on breaking in to a play-off at last week’s Open, followed gains at the 16th and 17th with a 20-foot birdie putt at the last to close a four-under 68 and set the clubhouse target at 17 under.??
That left Hearn, who had held a two-shot lead heading in to Sunday, and Bubba Watson, who headed to the 18th with four birdies in his previous five holes, needing to card an eagle at the last to force a play-off.
Hearn found the bunker and two-putted to close with a five, while Watson left his eagle putt from thick grass off the green a foot short.??
A three-under 69 was enough for Watson to claim outright second while Hearn, who appeared on course to become the first Canadian in 51 years to win their home Open, ended the final round level par despite opening with back-to-back birdies.
Ollie Schniederjans, making his professional debut after a strong showing at St Andrews, fired seven birdies in his final round but still closed with an up and down one-over 73.??
Day told @PGATOUR: “The first thing I said was, I’ve got to get the ball to the hole this time.”
Hearn is thrilled to be in his current position, but does not believe he is the favourite heading into the final round where he will play alongside major champion Watson.
Hearn said on pgatour.com: “This is something you dream of. I feel like I’m ready to step up to the challenge.
“Hopefully, I can make some birdies and David can beat Goliath.”
