Teenager Chanettee Wannasaen played a five-hole stretch in 6 under early in the final round Sunday and closed with a near-flawless 9-under 63 for a four-stroke victory at the Portland Classic to become the first Monday qualifier to win on the LPGA Tour since 2015. Wannasaen arrived at Portland ranked 367th and having missed nine straight cuts in her rookie season. The 19-year-old from Thailand put together four stellar rounds in the 60s at Columbia Edgewater and shattered the tournament scoring record by five strokes with a 26-under 262 total for her first LPGA Tour victory.
