What's In My Bag: Lexi Thompson\nAge: 18 | Resides: Coral Gables, Fla. | Story:Became the youngest American to play in the Solheim Cup this year and was the youngest LPGA winner at age 16 in 2011 (before Lydia Ko won at age 15 in 2012).\nSTRONG SUPPORT SYSTEM\n\n One of my parents follows me around at every event I play. It means so much to have such a strong support system, especially when I'm making the most crucial decisions of my life, like turning pro in 2010. I'm so close with my brothers. We used to play matches for chores when we were younger. Whenever we're home at the same time (Nick is on the PGA Tour, and Curtis plays for LSU), we'll play together. The matches get intense! I owe so much to my family for making me who I am.\nSUPERSTITIOUS? GUILTY\n\n I'm definitely a superstitious golfer. If I play well one day of the tournament, I'll eat the same thing the next day. If I change, it just gives me a different feeling. Why mess with it? Also, if I'm playing well I won't change balls, even if it's scuffed up. I do love giving balls to fans, though. If I can put a smile on someone's face, I will!\nDRIVER\n\n My Cobra AMP Cell Pro driver (7.5 degrees, Fujikura ZCom Six shaft, X-flex, 45 inches) is probably my strongest club -- it suits my swing really well. This shaft model is almost as old as I am, but it works great for me.\nFAIRWAY WOOD\n\n If the club is working, I don't change it. I've played just one fairway wood -- this Cobra S3 3-wood (Graphite Design Quattro Tech MD6, S-flex) -- since I turned pro.\nIRONS\n\n I play Cobra S2 Forged irons (4- through pitching wedge, Royal Precision Project X 5.0 shafts). My ball flight is consistent with these, so they haven't changed since I turned pro.\nHYBRID\n\n Hybrids are great for female players. I've used my Cobra Baffler T-Rail (17 degrees, Aldila NV 85S) since 2011. Anything with more loft, though, and I prefer an iron.\nWEDGES\n\n I can control the spin perfectly with my Callaway X Forged wedges, which are all bent a degree strong (51, 55 and 59).\nPUTTER\n\n I've played this Odyssey White Hot XG 330 putter (34 inches) for the past five years. I'm so comfortable with it. I've always used a mallet putter on tour. I get too much face rotation with a blade.\nA RARE CHANGEUP\n\n I recently switched to Callaway's HEX Chrome+ prototype. They stopped making the ball I had been using, but I haven't lost anything with this one. I mark my ball with "LT."\nMY SWING FUEL\n\n I'm a big breakfast person: Eggs, bacon and yogurt is my go-to meal before a round. On the course, peanut-butter-and-jelly sandwiches are great for energy, but a protein bar works, too.\nLADYBUG LOVE\n\n My obsession started when I was 12 or 13. A little guy landed on me, so I blew him off, made a wish and it came true. I'll always stop on the course if I see one!\nMAXED-OUT FUN\n\n I'm all about bold statements. I like standing out, as you've noticed after seeing my outfits! It's why I signed with Cobra Puma, and it's what I love about Red Bull.\nSTANDING TALL\n\n I wear my Wounded Warrior pin anytime I'm at the course, and these chains are on my bag. The bracelet is from Bands for Arms. I love raising awareness to support our troops. It's inspiring when I think about it on the course.
