* Mater Dei at Fountain Valley, 3:15 today: Top-seeded Mater Dei has been pushed to the limit in 1-0 Division I victories over El Toro and Los Alamitos (10 innings), but the major question involves Fountain Valley (19-12). Which Barons’ team will show up, the one that beat Pacifica and Marina, or the one that lost twice to Edison?

* Woodbridge at Marina, 3:15 today: Top-seeded Woodbridge is 27-5-1. The Vikings (24-5) haven’t been dominant in Division II playoff victories over Dana Hills (3-2, nine innings) and Aliso Niguel (2-1) but have played well in big games this season.

* El Modena at Pacifica, 3:15 today: Top-seeded Pacifica (26-3) has the best pitcher in Division III in Amanda Freed, but El Modena (22-5-1) has beaten two of the three teams that have beaten the Mariners, Foothill and Fountain Valley.

* Santa Fe Springs St. Paul vs. Rosary, Lion’s Field, 3:15 today: The Royals try to avenge a 4-1 loss this season to third-seeded St. Paul (22-4).

* Calvary Chapel vs. St. Margaret’s, Cook Park, 3:15 today: Academy League champion St. Margaret’s (19-1) has won two in a row by 1-0 scores. Olympic champion and second-seeded Calvary Chapel (20-4) has scored 20 in its two Division V victories.
