4. Westview (9-2) @ Scripps Ranch (7-3)

Prediction: Scripps Ranch 33 Westview 31

3. Carlsbad (6-5) @ Chula Vista (7-3)

Upset Alert: Carlsbad, a team that start shaky after at 52-3 whipping from La Costa, has rebounded since then and finals got over the .500 mark with their last minute win against Torrey Pines. Like Mission Hills, which Carlsbad team will show up. The road warrior Lancers, homeless the entire year due to toxic soil on their field, will come out fired up and squeak out a victory against an overrated Chula Vista Spartans (who also got creamed by La Costa Canyon in week 0)

Prediction: Carlsbad 28 Chula Vista 27

2. Mission Hills (7-3-1) @ Poway (8-3)

Upset Alert: Mission Hills, the underdog, comes into the game as the second round wild card team. They've played very well at times during the year, particularly against La Costa Canyon, but underperformed against Torrey Pines. Which Mission Hills team will show up against the Palomar champion Poway Titans? Quarterback Zapata will come out strong and take down the Titans.

Prediction: Mission Hills 24 Poway 21

1. Vista (7-4) @ La Costa Canyon (8-2)

Both teams pride themselves on defense. Both teams beat Escondido. Both teams lost to south section power Mission Viejo by similar scores. Both teams have beaten each other in playoff games in past years. In a game of Gangrene vs. Blackshirts, who wins? If La Costa Canyon resists complaceny, they will win the game. They are the better team all-around. The spotlight is on Coach Darrin Brown - how will he prepare a confident La Costa Canyon squad against a dangerous Vista team that is on a mission?

Prediction: La Costa Canyon 28 Vista 20
