Seth Blair scattered three hits over seven innings as No. 1 national seed Arizona State cruised into the championship game of the Tempe Regional with a 12-1 victory over Hawaii on Saturday night.
Blair (12-0) was totally in command, giving up one run, striking out eight and walking none for the Sun Devils (49-8). His only blemish was a seventh-inning homer by Jeffery Van Doornum.
The Rainbows (34-27) will face San Diego in an elimination game Sunday. The winner must then beat Arizona State twice to advance.
Zack MacPhee went 4 for 5 with a two-run homer and three RBIs, Johnny Ruettiger drove in three runs, Deven Marrero hit a two-run homer and had three RBIs, and Raoul Torrez and Kole Calhoun hit solo shots.
Blair exhibited the style that has most analysts projecting him as a first-rounder when the MLB draft begins Tuesday. He consistently worked ahead, went to only three three-ball counts and struck out five of six batters over the third and fourth innings.
Blair was also backed by some stellar defense. Torrez twice robbed Hawaii's David Freitas by snaring line drives at third. MacPhee ranged far to his left on the outfield grass to throw out Kolten Wong leading off the fourth, and he backpedaled well into the outfield to grab Pi'ikea Kitamuras pop in the eighth.
Aggressive as always, Arizona State also stole four bases.
MacPhee's homer to right-center in the second chased Hawaii starter Josh Slaats, who was tagged for six runs (five earned) on five hits in 1 1/3 innings. Alex Capaul went the next seven innings, giving up six runs on 10 hits.
