Lexi Thompson's major championship season just got a major boost.
The 20-year-old American played her first six holes at the Evian Championship, the year's final major, in 5-under and cruised along with 12 more pars from there to post an opening-round 66 at the Evian Resort Golf Club.
That 5-under total was good enough for a share of the first-day lead, but Thompson took a precautious tone after her low 18-hole score.
"You just have to take one shot at a time and not get ahead of yourself because, I mean, shots can get away from you out here," Thompson said.
