Debbie Kim, Megan Mahoney, Emily Tierney and Jill Wery try to become only the second San Diego County contingent to win the 15th annual Girls Junior Americas Cup when stroke play begins on Tuesday.

Kim (Poway), Mahoney (Chula Vista), Tierney (San Diego) and Wery (San Diego) begin the 54-hole tournament Tuesday at Escondido Country Club, the first time the tournament has been hosted by the San Diego County Junior Golf Assn. It won’t return to San Diego for another 18 years.

Team members were selected by their respective associations. All girls are 13-17 years old.

The opening ceremony for participating U.S. states (12), Canadian provinces (two) and countries (three) takes place at 5 p.m. tonight and the tournament begins Tuesday at 8 a.m. Admission is free.
