With boys basketball, Burnaby South puts an end to St. George’s season at Lower MainlandsThe Triple A girls basketball championships will have at least three Fraser Valley teams finish in the top four placings for the fifth time in the past six years this season.One of Friday’s late quarterfinals at the Langley Events Centre features an all-Langley matchup between the No. 2 Walnut Grove Gators and the No. 6 Brookswood Bobcats, while the other has the No. 1 Semiahmoo Totems of Surrey facing the No. 5 Kelowna Owls.The championship game is Saturday at 5 p.m.The 2016 campaign is the outlier when it comes to recent Fraser Valley dominance, and it still featured two teams from the zone making the semifinals. Brookswood beat Richmond’s R.A. McMath Wildcats in the final, while the Oak Bay Breakers of Victoria upended the Lord Tweedsmuir Panthers in the third-place game.There are back-to-back-to-back championship games Saturday at LEC, with Double A girls preceding the Triple A with their 3 p.m. title game, and the junior girls getting the first-place games started with their 1 p.m. matchup.The reigning champion and top-seeded South Kamloops Titans are meeting the No. 5 St. Thomas Aquinas Saints of North Vancouver in one Double A semifinal on Friday, while the No. 2 Langley Christian Lightning are playing the No. 3 GW Graham Grizzlies of Chilliwack in the other.With the juniors, it’s the top-seeded Terry Fox Ravens of Port Coquitlam against the No. 13 MEI Eagles of Abbotsford and No. 2 Kelowna versus the No. 3 Riverside Rapids of Port Coquitlam in Friday’s semifinals.• • •Going over the box scores from Thursday’s four quarterfinal matchups at the Triple A tournament, the games featured nine lead changes combined. Seven came in Kelowna’s 65-64 win over the No. 4 Yale Lions of Abbotsford.The other two were in Brookswood’s 90-86 win over No. 3 Riverside. Riverside trailed much of the game and rallied late to overtake Brookswood for a time, only to have the Bobcats grind out a victory in the final few minutes. According to the scoresheet, Brookswood led for 37 minutes, 54 seconds.There were no lead changes in the Walnut Grove Gators’ 86-45 win over the No. 7 Robert Bateman Timberwolves of Abbotsford, nor in Semiahmoo’s 86-33 triumph over the No. 8 Okanagan Mission Huskies of Kelowna.And, if you’re wondering, lopsided scores in the quarterfinals aren’t uncommon. Three of the four Thursday games last year were decided by 29 or more points.• • •The boys basketball provincials are next week, and the reigning Quad A champion Burnaby South Rebels were still in the hunt to return to the LEC as of Friday morning, despite some unusual circumstances.The Rebels were the top seed at the Lower Mainland championships but had to forfeit their tournament opener due to using an ineligible player and were forced to the consolation side of the bracket.They won their next three games after that, including ending the St. George’s Saints’ season Thursday night with a 97-77 triumph at the Richmond Oval.That put Burnaby South into the Lower Mainland’s third-place game against Vancouver’s Churchill Bulldogs Friday night at the Richmond Oval, with the winner advancing to the LEC and the loser finished for the season.The Vancouver College Fighting Irish and Kitsilano Blue Demons are playing Friday for top spot. They both have qualified for the provincials.The Rebels were No. 4, the Blue Demons No. 5, Fighting Irish No. 6 and Saints No. 7 in this week’s provincial rankings, which can be found at Howard Tsumura’s varsityletters.ca page.
