Senior southpaw Chris Castellanos struck out a career-high 12 in eight scoreless innings to lead No. 20 Stanford to its eighth straight win and second straight sweep, 3-1 over No. 12 Arizona on Saturday at Sunken Diamond.

Stanford (27-12, 11-7 Pac-12) earned its first sweep over Arizona since 1999 to prolong the program's longest winning streak in four years. The Cardinal, which won all three games at Oregon last weekend, has swept back-to-back Pac-12 series for the first time since May 2012 against Washington State and Utah (also Stanford's last six-game Pac-12 win streak).

Sophomore Nico Hoerner and freshman Daniel Bakst provided the offensive support with a combined five hits and all three RBIs.  

Hoerner and Daniel Bakst gave Stanford an early lead with a pair of two-out RBI in the third inning. Hoerner blooped one in to center to score Matt Winaker and, two batters later, Bakst pushed one through the middle to bring home Hoerner.

Castellanos did not allow a base runner through the first three innings. The Wildcats got the first two on in the fourth, but the southpaw stranded both Wildcats in scoring position.

Hoerner and Bakst came through again in the fifth. Hoerner led off with a double into the left field corner, and Bakst lined a single to center to give Stanford a 3-0 edge.
