The 122nd Massachusetts Women’s Amateur Championship will come down to Shannon Johnson vs. Isabel Brozena.

Johnson, 42, of North Easton and Thorny Lea Golf Club, and Brozena, 19, of North Reading and Indian Ridge Country Club, captured quarterfinal and semifinal victories at historic Concord Country Club on Thursday.

The championship will be decided in an 18-hole match Friday. Play will begin at 8 a.m.

Johnson, the top seed, ousted Alexis Florio of Woodland Golf Club, 1-up, in a spirited semifinal match. In the other semifinal, Brozena won the opening hole and never looked back en route to defeating Molly Smith of Westford and Vesper CC, 3-and-2.

Johnson earned medalist honors by posting a 6-under score after 18-hole stroke play Monday and Tuesday. Smith was one shot back, while Brozena finished at 3-under.

Smith was trying to become the second member of her family to win the title. Older sister Morgan Smith was the 2022 and 2024 champion. Morgan Smith was eliminated in the Round of 32 on Wednesday.
