What's In My Bag: Brooks Koepka\nAge: 25 | Resides: Jupiter, Fla. | Story:Won the 2015 Waste Management Phoenix Open. Was 2014 European Tour rookie of the year after winning in Turkey.\nTRENDING UPWARD\n\n I'm nowhere close to the pinnacle I want to achieve. It's one thing to make it on tour and win. But I want to be contending in majors and making the Presidents and Ryder Cup teams. I still have a lot to accomplish.\n\n FIND ME ON THE WATER\n\n When we're home, anything in the water is fair game. Fishing, surfing, wakeboarding. I grew up on the water.\nspecs: Titleist 915D2, 9.5 degrees, Mitsubishi Rayon Diamana White+ 72 shaft, X-flex, 45 inches, D-2\n\nThere's a lot to like about driver technology today. The low spin helps me control the flight into the wind or downwind. The ball never seems to move off line.\nspecs: Titleist 915Fd, 15 degrees, Mitsubishi Rayon Diamana White+ 82 shaft, X-flex, 43 inches, D-3\n\nI love hitting a low bullet off the tee with this club on a shorter par 4. I can hit a ton of shots with it. I use it mostly off the tee, but it works off the fairway when I need it.\nspecs: Titleist 915Hd, 20.5 degrees, Mitsubishi Rayon Dia-mana White+ 92, X-flex\n\nOut of rough, off the tee -- I'll use it a lot. The lower spin works with my swing.\nspecs: Titleist 714 CB, 4- through 9-iron; True Temper Dynamic Gold X100 shafts, Golf Pride Tour Velvet Midsize grips\n\nThese are crucial clubs for me. I have all the confidence in hitting my driver far. But it's about nailing my approach shots, from anywhere I find myself on a hole.\nspecs: Titleist Vokey SM5: 48, 52, 56 degrees. SM4: 60 degrees. True Temper Dynamic Gold S400 shafts\n\nI just switched to this wedge setup the week before I won in Turkey. Having a pitching wedge that's part of my other wedges helps my feel and trajectory.\nspecs: Titleist Scotty Cameron Newport 2 SLT T10 prototype, 15-gram heel and toe weights\n\nI've had this putter since college. And I put it back in play right before I won in Phoenix.\nKeep it simple\n\n I'm not superstitious at all. I keep everything pretty clean. Wedge stampings just say BK. Same goes for my ball mark. Just a red dot on my Titleist Pro V1x.\nHead of the states\n\n There's nothing crazy about my ball-marker choice. I have a lot of state quarters. It's a fun look. I'm partial to any Florida state quarter, too.\nTee game strong\n\n I have fun with my tees. My initials BK and "Lounge" are on them. It's an ode to comedian Dane Cook's skit about Burger King.\nDoing it 'My Way'\n\n I don't listen to music while I practice. But when I'm done, I listen to rap. Fetty Wap (pictured) and Wiz Khalifa are on the playlist now.\nExtended family\n\n Claude Harmon III (far right) is my coach. He and his dad, Butch, have taught me a lot.\nAnything you can do ...\n\n My roomie, Peter Uihlein (right), was the top rookie on the European Tour one year before I was. We're on our way to fulfilling our goals.
