Trish Ronchi and Barb Olson will be back to defend their respective titles when the 73rd annual Nemadji Women's Invitational tees off at 8:30 a.m. Wednesday at Nemadji Golf Course.

Ronchi’s recent dominance at Nemadji included a tournament-record (and personal-best) score of 68 last year. She also finished second in 2017 — losing a one-hole playoff to Silver Bay’s Norma O’Leary — and finished first in 2015.

The previous tournament record was 70 by Hermantown’s Deb Showalter in 2004.

Ronchi’s rounds of 34s on the North and South courses last year included four birdies. The only blemish on her card was a bogey on the North No. 5 hole.

O’Leary and Showalter are also back this year and the three will be joined in the championship flight by Superior’s Pat Kelly; Esko's Sami Mattson; and Duluth's Amy Patenaude, Diana Mueller, Nicole Frederickson and Hannah Cornwell.

O’Leary has won 11 Nemadji titles, while Showalter has six titles.
