The 30-year-old American has won 10 times on the LPGA Tour, including the 2010 US Women's Open.
Q Favourite tournament and why?
A The HSBC Women's Champions has such a special place in my heart. Goes definitely into No. 1 in terms of memories, especially after that putt (she sank a 75-foot eagle putt on the second play-off hole to win the 2014 edition).
Q How many different putters do you have in your garage?
A Oh gosh. Maybe 60? That's just in my house. My dad has the rest at his place.
Q Best golf shot ever seen?
A Tiger Woods' chip at the 2005 Masters (for birdie on the par-three 16th hole during the final round) was amazing. For women, when Karrie Webb (using a pitching wedge from 116 yards) holed out for eagle on the par-five 18th hole at the ANA (formerly known as the Kraft Nabisco Championship, in which Webb won in 2006 in a play-off).
Q Greatest athlete in the world?
A Michael Phelps. It's so hard to name just one person because every sport is so different but my goodness, what he has done and accomplished is incredible.
Q Favourite social media app?
A I like Snapchat even though I'm not super into it quite yet. I just signed up late for it. So Instagram. I like the filters (laughs).
Q Worst score on a single hole?
A A 17 on a par-five. I hit a lot of balls out of bounds, maybe six times. I was 12 years old. It was up this big hill and I just couldn't hit the fairway. It was a crazy hole. This was in junior golf and I didn't end up winning by four or five shots. If I had shot an 11, I would have won the tournament.
Q What did you buy with your first serious pay cheque?
A I bought my first car. It was a BMW M6 and the colour was black on black. Her name was Black Beauty.
Q Hardest thing about golf that people don't realise?
A Being patient throughout your round. You can hit great shots and get bad bounces. You can hit great putts and the ball doesn't go in. You have to just keep persevering because it's not always going to be bad. There'll be a moment when it's a good thing, either a good bounce or it lips in on your putt.
