MOBILE, ALABAMA | When Sunday began, Jennifer Johnson wasn’t even in the conversation. Not only had the third-year player never been in contention to win an LPGA Tour event, she had only finished in the top 10 once. So, remarkably, Johnson came figuratively out of nowhere to win the Mobile Bay LPGA Classic, her first victory. She shot matching 65s on the weekend to finish four rounds at the Magnolia Grove Crossings Course at 21-underpar 267, good for a one-stroke margin on Jessica Korda and Pornanong Phatlum. There was nothing in Johnson’s play that might have predicted this victory. This was her ninth start on Tour this year and her best finish was a tie for 13th at the Kraft Nabisco. She missed the cut in the Kingsmill Championship, her last start prior to her victory. After returning home from Virginia, Johnson went to see her teacher and put an old putter back in the bag, a Scotty Cameron model that her father calls “the spaceship.” “The putter has been the missing link,” said Johnson, 21. “When they go in, it really helps the score.” Johnson had only one top-10 finish in her career, with her best a tie for eighth at the 2011 Navistar LPGA Championship, also in Alabama.
