CHATTER: NEW RULES FOR FALL.

Byline: Lee Barnathan Daily News Staff Writer

Say goodbye to intrasquad football scrimmages the week before the season begins. And welcome back scrimmages between teams.

The Southern Section, by a 32-30 vote, decided last week to allow schools within a 30-mile radius to scrimmage against each other the week before the season starts. Teams haven't done that since 1977.

``I think it's a good thing,'' Hart coach Mike Herrington said. ``I know the powers that be feel we want to turn that into an 11th game like the junior colleges have, but that is farthest from the truth. Coaches don't want to play an 11th game. (A scrimmage) is a better indication of evaluating talent.''

Right now, City Section schools are not included, but administrator Jeff Halpern said the City is moving in that direction. . . .

Soon, Julio Castillo again will discover life without Terry Davila.

Davila, who played soccer at Reseda High and Cal State Northridge and later coached Castillo at Reseda, took the Northridge men's coaching job last week. Before, he had been helping Castillo, who is the Reseda boys' soccer coach.

Castillo owes much of his success to Davila. He freely admits Davila helped him learn how to coach and discipline his players.

Now Davila's gone, but he's confident Castillo is ready to go it alone. . . .

Next year's Simi Valley basketball tournament will be stronger with the addition of Chaminade and Washington Union of Fresno (with top national player DeShaun Stevenson). . . .

Jennifer Jenkins, a 5-foot-9 junior right-hander, has yielded just one earned run in 98 innings with 13 shutouts, three no-hitters and 132 strikeouts. She is batting .444. . . .

It doesn't happen often, but high school teammates faced each other last week in the major leagues. On Thursday night, Montclair Prep teammates Russ Ortiz (Giants) pitched to Brad Fullmer (Expos). Ortiz won the battle, holding Fullmer hitless. The Giants won the game and Ortiz was the winning pitcher. . . .

Club soccer teams are numerous around the valleys, but few are as successful as Adolfo Perez's L.A. Force girls' teams. Several of players have won California Youth Soccer Association titles and earned college scholarships, including Sabrina Love to St. Mary's, Melissa Cleal to CSUN, Jennifer Valentine to Pennsylvania and Lindsey Horn to Cal Poly San Luis Obispo.

Now comes the new generation. The under-15 team won the 48-team CYSA State Cup Open championship, outscoring the opposition 32-3 in eight matches.

Among those players, now appearing on area fields: Tara Donoghue (Chaminade), Courtney Diamond (Kennedy), Natasha Case and Lindsey Kimura (Harvard-Westlake), Megan Porter and Jamie Doyen (El Camino Real), Ericka Reisig (Grant), Karen Loftus (Westlake), Jamie Marcus and Lana Fogel (Calabasas), Chelsea Welch (Burroughs) and Jenna Graffman and Lindsey Kohon (Notre Dame). . . .

Last year's Diver of the Year, Christina Flynn of El Camino Real, signed with Cal. . . .

Chaminade basketball players Cayce Cook and Darren Tarlow are heading to Division III Redlands, and Clarence Mitchell has committed to Claremont College. Former Chaminade player and current Moorpark College player Justin Beach will play at Division II Quincy College next year. . . Becky Rauth of Harvard-Westlake has made a commitment to run track at Yale. Rauth finished second last season in the Southern Section Division III finals as a junior.
