The Timberwolves followed that up with another stunner.

Led by senior pitcher Wyatt Bauer’s 1-hitter, 11th-seeded Sierra knocked off No. 6 Placer 8-0 in the first round of the Sac-Joaquin Section Division IV playoffs Wednesday in Auburn.

Bauer issued three walks but struck out 11 in his complete-game masterpiece.

Junior Ryan Reyes added a double of his own, going 2-for-3 with a run and two RBIs. Riley Kane contributed two hits, a run and an RBI.

Jack Addison got the lone hit for Placer (16-13).
