SAN FRANCISCO — Defending champion San Francisco blanked BYU baseball Thursday afternoon, 12-0.

The Cougars (17-16, 6-4) were bounced from second place in the West Coast Conference by the Dons (20-25, 7-6) by virtue of 10 unearned runs.

Compounding BYU’s four errors was an offense that stalled with bases loaded situations in the second and third innings as USF’s lead soared to 8-0. BYU tallied four hits, all singles through three innings until Brock Whitney doubled in the ninth. USF belted 13 hits, including three doubles.

The Dons’ third baseman Aritz Garcia went 2-for-3 with three RBIs, and catcher Mason Marioca, a high school teammate of BYU pitcher Marc Oslund, went 2-for-4 with a pair of RBIs in the shutout.

That shutout was the first for BYU since a 5-0 loss at No. 4 Arkansas last February.

The two teams will meet Friday afternoon when Oslund takes the mound for the second of a three-game series at Benedetti Diamond.
