Form held in the open division of the Baton Rouge prep bowling regional at All-Star Lanes on Monday, with only one higher seed going down in the 8-9 match as Baton Rouge High beat Catholic High 17-10 as Keondra Eaton had a 236-599.

Other winners were No. 2 seed Dutchtown, remaining undefeated with a 26-1 win over Woodlawn behind Trey Kauffman’s 637 and Chad Conard’s 628. No. 3 had a 17-10 win over East Ascension; fourth-seed Broadmoor won 19-8 over Denham Springs behind Austin Vicari 223-644); No. 5 seed St. Amant won 25-2 over Tara; sixth-seed Madison Prep behind Brinkley Robinson (631) defeated Zachary, 22.5-4.5, and seventh-seeded St. Michael got a 22-5 decision over Redemptorist.

The 1:15 p.m. matches Wednesday in the Baton Rouge regional open division will have Broadmoor meeting St. Amant, Runnels facing Madison Prep, St. Michael against Dutchtown and top-seed Central over Baton Rouge High. The four winners will automatically advance to the biregional. The four losers will then bowl at 3:15 for the final two spots in next week’s event.

In the girls division, two preliminary matches were contested with Denham Springs — behind Ashley Hewes’ 638 — taking a 21-6 decision over St. Amant. The St. Michael girls advanced with a 16-11 win over East Ascension. But Bailee Chapman of East Ascension is definitely still alive in the singles competition after shooting 234-622.

Wednesday at 1:15 p.m., the top seeded Central girls will face Denham and St. Joseph’s Academy will meet St. Michael with the winners advancing. The losers will meet in a 3:15 p.m. for the final biregional spot.

The top four open division seeds from the New Orleans area region advanced on the opening day of the playoffs at Kenner’s All-Star Lanes and will compete in the Baton Rouge-New Orleans biregional March 31.

Brother Martin, Archbishop Rummel, Jesuit and Archbishop Shaw all won easily to remain alive.

Second seed and two-time champion Rummel was a 22-5 winner over Holy Cross — a 26-1 winner over St. Thomas Aquinas — in the best of 27-point three-game matches. Third-seeded Jesuit knocked out Albany 24-3 after Albany beat St. Augustine 21-6.

The biggest upset came as the defending champion from Albany, just a four-seed in the New Orleans regional, beat Holden 18-9 and then knocked off No. 1 seed Cabrini 20-7 to advance to biregional.
