“We live in an age of entitlement,” Corisis said. “Unfortunately, in our society, mediocrity is accepted now.” It has never been acceptable to Corisis, who recorded his 500th career victory Feb. 21 – 40-34 over St. Joseph’s of Santa Maria. His 502 career wins (all at Palmdale) lead in the Daily News coverage area and place him eighth in the state. This year, he’s pushed a team that many had written off before the season started.

PALMDALE – Nothing done by the Palmdale High girls’ basketbll team should come as a surprise, given its tradition of pulling off shocking upsets. Soon after coach George Corisis took over the unheralded program in the early 1980s, the team pulled off improbable playoff upsets over San Gabriel and Foothill of Santa Ana, considered among the state’s elite. But these days, Corisis might have outdone himself. Palmdale has come through a series of obstacles to advance to tonight’s Southern Section Division II-A semifinals. The Falcons (18-11), who have never won a section championship and are seeking their first title game appearance since 1996, will play Temescal Canyon of Lake Elsinore (22-6) at 7:30 p.m. at Lakeside High of Lake Elsinore. Palmdale is coming off a 52-45 upset of Vista Murrieta on Saturday, a No. 2 seed that it trailed 14-3 early in the game. Corisis stresses fundamentals in practices, even in late February, when most of his coaching counterparts allow their players to scrimmage. His teams are known for playing hard-nosed, in-your-face defense. Corisis said he has adjusted to today’s players, whom he finds less accepting of criticism, but is an admittedly demanding coach who pushes players and doesn’t always tell them what they want to hear.
