George Horton had never seen 20 runs on an opponents’ box score during his time at Oregon.

The 11th-year coach also couldn’t recall that many runs being scored against him during 17 seasons on the staff at Cal State Fullerton or his six seasons coaching Cerritos College at the beginning of his baseball coaching career.

“You try to forget those and that is what I will tell the guys,” Horton said after second-ranked Stanford beat the Ducks 20-5 Friday night in front of 1,366 at PK Park. “That is one you throw in the trash can and get ready for tomorrow.”

Stanford’s first five batters all reached base and scored before Oregon starter Cole Stringer recorded an out. The Cardinal scored in six different innings to match the most runs against Oregon since Washington State scored 20 in 1981.

Andrew Daschbach was 4-for-5 with two homers and Brandon Wulff continued to beat up the Ducks with three hits, including a homer. Stanford’s 24 hits included five home runs, giving it eight homers in two games against Oregon.

“They whooped us every which way, shape and form,” Horton said. “Live conditions with the wind blowing out and good hitters standing behind the ball with leverage. When you don’t make pitches, they make you pay for it and they did that all day.”

The Ducks were encouraged by a 5-4 loss to the Cardinal on Thursday, but have little turnaround time to regain good thoughts before the series finale at noon Saturday. Stanford (26-6) leads the Pac-12 at 12-2 while Oregon (22-15) fell to 7-7.

“Our guys are competitive and will not roll over,” Horton said. “Every game we win in conference keeps us in the mix a bit so it will be a big one to get back off the deck and do something about it. … We have been challenged and come back before, against Washington and Arizona State we were able to do that.”

Kyle Stowers and Maverick Handley each singled to open the game before Wulff walked. Will Matthiessen hit a two-run double and Daschbach followed with a three-run homer.

“The good news when you give up a crooked number early is that there is plenty of time to chip away,” Horton said. “Instead, they kept extending with more crooked numbers.”

Wolff stretched Stanford’s lead to 6-0 with a solo homer in the top of the third inning, his third home run of the series.

Gabe Matthews hit a solo home run in the fourth inning for Oregon’s first run. That was one of six hits for the Ducks.

“We’d have good at-bats and then crummy at-bats after that,” Horton said. “No consistency from anything on the mound or offensively. The scoreboard is indicative of how much we got whooped.”

Stanford added four runs in the top of the fifth inning to knock Stringer out of the game.

Stringer allowed eight hits and eight earned runs in four innings before Brett Walker game up four hits and two earned runs in an inning.

The Cardinal added six runs in the sixth inning after Handley led off with a homer against Walker.  Brandon Dieter later hit a three-run homer to put the Cardinal ahead 16-1.

Matthiessen earned the victory by allowing two hits and one earned run in five innings while striking out six Ducks.

Oregon’s Taylor Adams hit a grand slam in the bottom of the eighth.
