Phil Mickelson is in a positive frame of mind ahead of The Open Championship at Muirfield this week, after claiming his first individual tournament victory in Britain last weekend.
The 43-year-old won the Scottish Open at Castle Stuart, and attributed that triumph to a significant improvement in his putting, though he held back from divulging the secret behind his recent success.
"The common thread (to previous failures) is, I believe, more on the greens than anything," Mickelson is quoted by Sky Sports. "But I am really optimistic about this week and going forward because I'm starting to putt as well as I ever have.
"I putted great last week, and more than that I've been putting well now for months, and feel like I've really keyed in on something.
"I believe I have kind of found the secret to my own putting and what I need to do to putt well."
The four-time major winner also revealed that he will not be packing a driver in his bag at Muirfield, re-emphasising his intention to focus more on his short game, as he bids to improve on a poor record that has seen him card four top-20, and only two top-10 finishes in 17 appearances at The Open.
Lefty's win at the Scottish Open was his first on European soil since 1993, and now there is genuine hope that he will compete for a Claret Jug this week.
Pressed for an answer to his putting solution, Mickelson added: "I'm not going to discuss it because I don't really want to share.
"[But] I think that last week was a very positive sign for me and hopefully that one common thread that's given me problems here I hopefully have solved."
