On Sunday in Mobile, Alabama, Alexis (Lexi) Thompson faced her first opportunity in her ripe age of 16 to close a professional event, the Avnet LPGA Classic, and to become the youngest winner in history. Who wouldn’t have loved to see Lexi make history? It sure would have been a boost for women’s golf and could only help the LPGA’s sponsor woes. But Lexi’s youth and inexperience hampered her efforts in the final round. Perhaps it just wasn’t her day. And maybe she should make a caddie change.
