SAN FRANCISCO — This is one week where Jason Day is not trying to make friends.
The Match Play Championship brings out an edge in the 27-year-old Australian, who doesn't lack for confidence in any format and yet seems to crank it up a notch when he only has to worry about the guy he's playing.
It worked well for Day a year ago in Arizona when he never trailed over the final 53 holes and outlasted Victor Dubuisson to capture his first World Golf Championship.
"I really want to have a great record here and let everyone know that I'm one of the best match play players in the world," Day said.
