Alex Dunlap hit a three-run homer in the seventh inning but that was all the offense the Stanford offense could muster Saturday in a 4-3 loss to host Oregon in Pac-12 Conference action.
The Cardinal (5-15 Pac-12, 19-25 overall) lost its fourth in the past five games. That follows a stretch in which Stanford won seven of 10.
The same two teams finish their series in Eugene on Sunday with a noon start.
The Ducks scored all their runs in the second inning against Marc Brakeman (1-3), who settled in and retired the final 12 hitters he faced, giving Stanford a chance.
Brakeman, who missed 24 games with an injury, owns a 3.24 ERA in 14 innings since returning from the injury.
David Peterson (4-5) took a shutout into the seventh inning before allowing Dunlap's first home run of the year. Beau Branton walked and Jonny Locher singled ahead of Dunlap.
Brakeman and reliever Chris Castellanos combined to keep the Ducks hitless after the first three innings.
Stanford kept pace with No. 24 Arizona State for a majority of the game Saturday but was undone by a couple big innings, falling to the visiting Sun Devils, 16-6, in six innings in Pac-12 action Saturday.
The night was special for the Cardinal all the same as it honored its three seniors Erin Ashby, Alyssa Lombardo and Tylyn Wells as part of Senior Night for their contributions to the program throughout the duration of their collegiate careers.
"I'm proud of our seniors for finishing strong and being team-first and playing the role of whatever the team needs," said Stanford coach Rachel Hanson.
Stanford (16-34, 1-19 Pac-12) held leads in the third and fourth innings but Arizona State (32-18, 10-9 Pac-12) produced 11 runs in the fifth and six innings to earn the run-rule victory.
Kayla Bonstrom, Kylie Sorenson and Wells paced the Cardinal with two hits apiece, while Bessie Noll and Jessica Plaza each produced a hit.
Bonstrom's first hit of the game was a two-out two-run double that moved her into eighth all-time for RBI in Stanford history with 168. She added another RBI with her second hit to increase her career total to 169.
Noll continues to swing a hot bat and has at least one hit in nine of the past 11 games, and a RBI in two of the past three contests. Plaza is also heating up at the plate and has three hits in the past three games, including two home runs.
Sorenson, typically Stanford's starting shortstop but pitching due to injuries to starting pitchers, got the start in the circle and did well to keep her team within striking distance early. She did not allow a run through the first three innings and went 3 2/3 innings, permitting five runs two earned on six hits and four walks.
Erin Ashby (0-4), typically Stanford's starting second baseman, entered the game in relief in the fourth inning and did well to eat up innings to conclude the game.
"Kylie did really well keeping the ball low and had her off-speed working to keep them off-balance," said Hanson. "Erin showed again why she's a great senior and leader, stepping up to take care of business."
Stanford took a 2-0 lead in the bottom of the third inning when Bonstrom launched her double into the left-center field gap to bring in Sorenson and Wells.
The Sun Devils responded with five runs in the top of the fourth inning to take a 5-2 lead.
The Cardinal answered immediately with four runs in the bottom of the fourth inning. Plaza led off the inning with a big home run to left field her fourth on the season.
Noll, Sorenson and Bonstrom produced three more runs with consecutive RBI-singles to retake a 6-5 lead.
Stanford ran into trouble in the top of the fifth when Arizona State capitalized on two Cardinal errors to generate seven runs on seven hits and take a commanding 12-6 lead.
The two teams conclude their series Sunday at 2 p.m.
No. 1 Cal was too tough for No. 12 Stanford as they won all three races at the 82nd Big Row.
"Cal clearly proved why they are ranked No. 1," Stanford coach Craig Amerkhanian said. "They raced at the highest level we have seen here in years. We knew they would be tough going in and we could have raced better, but credit to them for having a great day."
The Big Row marked the final home competition for three Stanford seniors. Scott Roycroft (earth systems), Kaess Smit (mechanical engineering) and Andrew Terajewicz (biomechanical engineering) all concluded their home racing career. The three individuals have been great contributors to the program over the last four years.
In the varsity eight race, Cal posted one of the fastest times in course history with a 5:31.2. Stanford had its second fastest time at Redwood Shores this year with a 5:48.0, but the Golden Bears were too strong for the Cardinal's top boat.
The 2V8 race ended about the same away with Cal finishing 16.3 seconds ahead of Stanford. In the 3V8 race, freshman coxswain Ariana Qayumi made her collegiate debut as the Cardinal posted a time of 6:15.5. Cal won the race by a wide margin.
When you put two of the top 10 teams in the country against each other, and they are rivals, you are bound to get some exciting racing.
That is exactly what happened at the 82nd Big Row on Saturday at Redwood Shores. No. 2 Cal avenged its loss last year to No. 6 Stanford with wins in all four races. Each of the races were competitive, but it was the Golden Bears earning the sweep.
As has become the tradition, both Stanford and Cal wore special uniforms in honor of former Cal coxswain Jill Costello, who lost her battle with cancer. Stanford donned black tank tops with a pink ribbon and the Stanford block "S" in light blue on the front and Team Jill written along with the schools and date on the back.
"It's our privilege to race in honor of Jill Costello every year at The Big Row," said Stanford coach Yasmin Farooq. "Jill was an amazing person and the legacy she left was that this race is about so much more than the rivalry. It's about each team giving their very best. The racing was fast today. We gave it our all and Cal was the better team. We'll look forward to seeing them again in two weeks."
With the day coming to a close, the 2V4 had a spirited race with Stanford holding the lead once the two boats reached the Sofitel. However, in the final 10 strokes Cal was able to sneak ahead for the victory. Only 1.3 seconds separated the two boats with Stanford taking second with a time of 7:17.7.
The varsity eight race was also a nail-biter. The Cardinal gave Cal one of its toughest races of the season, but fell just short with a time of 6:16.5. The Golden Bears clocked a 6:13.0 for first.
In the varsity four race, only 3.6 seconds separated the two programs. Stanford finished in 7:21.5 after putting forth a strong effort.
Stanford won the PCCSC Coed Championships on Saturday and qualified for the national semifinals.
Sailing on its home course at the Redwood City Lagoon, the Cardinal accumulated 43 points. UC Santa Barbara finished second with 82 points, followed by USC (133) and Hawaii (134). All four schools advance to the semis.
