CHAPEL HILL — North Carolina is back in the women’s lacrosse Final Four but, for the second consecutive season, Stony Brook and its vexing zone defense didn’t make it easy. Just like in last year’s quarterfinals, the undefeated, No. 1-ranked and top-seeded Tar Heels (20–0) had to rally against the Seawolves to keep their season alive. UNC rebounded from the lowest-scoring half of the season (three first-half goals) and used a four-goal second-half run to advance Thursday at Dorrance Field. The Tar Heels’ 8–5 NCAA tournament quarterfinal victory over the No. 7-ranked Seawolves (16–3) was their 33rd consecutive home win.
