NASHVILLE, Tenn. (AP) -- Shaun Chase homered, doubled and drove in four runs Friday to lead No. 2 seed Oregon to an 18-1 thumping of No. 3 seed Clemson in the Nashville Regional.
The Ducks (43-18) had a season-high 20 hits.
Chase hit his 13th homer -- a three-run blast -- in the fourth inning. Tyler Baumgartner followed with a solo shot.
Oregon scored three in the second inning to pull ahead for good after allowing Clemson's lone run in the first.
Oregon's Tommy Thorpe (11-4) scattered five hits and four walks in seven innings.
Clemson's Matthew Crownover (8-6) struck out seven but allowed eight earned runs in 3 2/3 innings. Crownover hadn't given up more than four earned runs in any of his previous 29 career starts.
Oregon plays Saturday against the winner of Friday's game between No. 1 seed Vanderbilt and No. 4 seed Xavier. Clemson (36-24) faces the loser.
