CORVALLIS - Jack Anderson's steely stare morphed into a wide-eyed grin as he rounded third base Saturday, glancing at his teammates jumping up and down and holding their heads in giddy disbelief.

The Oregon State right fielder had connected on the first home run of his three-year college career with two outs in the first inning, the first sign the Beavers were destined for a thorough 11-0 demolition of Yale in their second game of the NCAA regionals.

"It was pretty crazy, a pretty cool way to start the game," said Anderson, a Lake Oswego native who as a child watched OSU win back-to-back national titles and has gone from a redshirt walk-on to first team all-Pac-12.

The Anderson bomb set the tone for arguably the most dominant start-to-finish showing in a charmed season for the No. 1 national seed.

Eight OSU players sprinkled 16 hits inside and outside the park, six of which came during a six-run sixth inning that pushed the lead to 11 runs. With two outs in the first three innings, Oregon State went 6 for 9 with one double, two home runs and one walk.

Designated as the visiting team at Goss Stadium, Oregon State (51-4) gave starter Luke Heimlich a two-run lead before he ever stepped on the mound. The Beavers' ace went on to carve up 3-seed Yale (33-17) over the course of seven innings, striking out eight hitters and giving up two hits and one walk while lowering his Division I-best ERA to 0.76.

Heimlich touched 94 miles per hour with his fastball and got out of his lone jam unscathed after Yale runners reached second and third with no outs in the fourth inning.

"Getting the lead early really helped," Heimlich said. "I was able to pitch off my fastball then and really be aggressive in the zone."

On the rare occasion Yale hitters made solid contact off the Pac-12 pitcher of the year, his defense back him up, most notably on a running warning track grab by centerfielder Elliott Cary to close the fourth and a leaping catch into the wall by Anderson in the seventh.

"I finally got one," Anderson said. "(Senior reliever) Max Engelbrekt was telling me I was like 0-for-5 on the wall catching balls."

The joke within a focused OSU post-game presser was no match for the sarcastic humor brought by Yale coach John Stuper after the loss. Stuper was effusive in his praise of Heimlich, calling him the best pitcher he had seen in 25 years of college baseball, and later jested he "must be a sadist" to want a rematch in the regional finals.

"This isn't a game that as a coach you lose sleep over, I got to be honest with you," Stuper said.

Oregon State enters Sunday in prime position for its first regional title since 2013. Nebraska - the 2-seed, Big Ten regular season champion and biggest name in the regional outside of OSU - was bounced Saturday with a 7-4 loss to Holy Cross, who will face Yale at 1 p.m. Sunday in an elimination game. Yale is 5-1 against Holy Cross this season.

Team co-captain Drew Rasmussen will take the hill at 7 p.m. Sunday against the winner of the elimination game, his fourth start since returning from Tommy John surgery. Rasmussen threw a season-high 84 pitches last Saturday.

The Beavers' coast-to-coast supremacy Saturday allowed late-inning rest for multiple everyday players, including left fielder Steven Kwan, who went 4 for 5 with one RBI while leading off for the first time since the season opener in February.

Casey moved second baseman Nick Madrigal from leadoff to the two-hole, noting that the Pac-12 player of the year is "continuing to not play at 100 percent" after getting hit by a pitch on his left hand on May 13. Madrigal went 0 for 3 with 2 RBI on Saturday and is 1 for 8 in the postseason.

Four Beavers had multi-hit games in addition to Kwan. Cary went 3 for 5 with a double out of the nine-hole, first baseman KJ Harrison went 2 for 4 with a home run and three RBI, catcher Adley Rutschman went 2 for 4 with two RBI and designated hitter Trevor Larnach went 2 for 4 with a double and one RBI.

Yale starter Eric Brodkowitz gave up 10 hits, four walks and nine earned runs in 5 1/3 innings and the Bulldogs used three relieves, while Sam Tweedt closed out the final two innings for OSU with no hits and three strikeouts.

Awe-inspired by the performance, Stuper entered the postgame press conference, noted the high number of media members compared to previous days and posed a question that very well could have applied to the matchup itself.

"It's a little different when you play Oregon State, huh?"
