Buena 20, Westlake 19--Running back Aaron Kleefisch's third rushing touchdown--a 24-yard run midway through the fourth quarter--led the Bulldogs to a come-from-behind upset at Westlake.
Kleefisch (27 carries, 135 yards) scored on two runs of 14 yards in the first quarter after Westlake had built a 13-0 lead just two minutes into the game.
Kleefisch's winning score came one play after linebacker Joey Williams recovered a Westlake fumble.
The Warriors were led by sophomore quarterback Zac Wasserman, who completed 28 of 43 for 341 yards and three touchdowns.
Wasserman threw an 80-yard touchdown pass to Joey Cuppari, a two-yard scoring toss to Kevin Howard and a 31-yard touchdown pass to Mike Seidman.
Cuppari, a senior who had 79 catches last season, had 12 receptions for 155 yards.
