It’s one big week after another at this time of the year for high school sports. Soccer, volleyball and cross-country have wrapped up their seasons, clearing the way for total focus on the remainder of the football playoffs. Three of the eight teams in the Class 6A quarterfinals are Portland-based: Grant, Central Catholic and Jesuit. Friday’s slate (all 7 p.m. starts): Grant (9-2) at Sheldon (11-0), Oregon City (8-4) versus Central Catholic (9-2) at Jeld-Wen Field, Tigard (11-0) at Jesuit (8-3), and Lake Oswego (11-0) at Roseburg (8-3). Grant is seeking its first semifinals appearance since 1964, and Central Catholic hasn’t been to the semis since 1953, when it won the second of back-to-back state championships. Grant has won five in a row this season, averaging 42.2 points per game in that span. The Generals are coming off a 41-14 second-round victory over Canby. Sheldon eliminated Lincoln 45-21. Central Catholic is on an eight-game winning streak. The Rams averaged 44.6 points per game in that stretch. They pulled away from Thurston last week, winning 48-27. Jesuit advanced with a 22-14 victory over Tualatin, but now faces a Tigard team that has scored 50.0 points per game while allowing 11.8. Lake Oswego has scored 45.7 points per game and beat West Salem 49-28 last week. Of this year’s quarterfinalists, Jesuit, Lake Oswego and Sheldon all went at least that far in 2010. Jesuit and Lake Oswego made it to the semifinals a year ago, with the Crusaders losing 26-22 to Tualatin, and the Lakers falling 17-16 to eventual state champion Aloha. Soccer: Grant and Wilson both came up short in boys state championship games last Saturday at Hillsboro Stadium. The Generals lost 1-0 to Westview in the 6A final on a goal by Jaime Velasco with 2:29 remaining. Grant finished with a 14-3-2 record. Wilson gave up two second-half goals after leading 1-0, and fell to Woodburn 2-1 in the 5A title game. Wilson went 14-2-2 this season. In the 3A/2A/1A girls final, Oregon Episcopal downed league rival Catlin Gabel 3-0 at Liberty High. Hannah Huston scored twice to give OES a 2-0 lead after 44-plus minutes, and Anastasiya Chevtchenko had an assist and the final goal for the Aardvarks. OES ended the year with a 13-3-2 record, while Catlin Gabel was 15-2-2. The teams had met twice during the regular season; Catlin Gabel won the second match 1-0 and played OES to a 1-1 draw in their first meeting.
