OJAI, Calif. – The Oregon men’s tennis team picked the perfect time to post its first come-from-behind victory of the season.

The Ducks (17-8, 3-6) used a trio of consecutive three-set singles wins to rally past third-seeded Stanford (14-5, 5-3), earning a shocking 4-2 victory on Thursday in the quarterfinals of the Pac-12 Championship. Once trailing 2-1, Jayson Amos, Kevin Farin and Robin Cambier each rallied to singles wins after losing their first sets to stun the field at Libbey Park in Ojai, Calif.

Seventh-seeded Oregon has notched the only two upsets of the tournament, defeating sixth-seeded Washington and the Cardinal to advance to the semifinals. Oregon has posted its first and second-ever wins at the Pac-12 Championship in consecutive days. Today’s win marked UO’s second victory over Stanford in program history. UO ended the Cardinal’s five-match win streak that included a 4-2 victory over Oregon less than two weeks ago.

“There isn’t a single player that didn’t gave everything they had for the program today,” said head coach Nils Schyllander. “We battled back all over the place. Today was an unbelievable team effort and a great win for the program.”

The Ducks lost the doubles point and trailed 2-1 after Stanford won the No. 5 singles match. With four matches into a third set and the team battling to keep its season alive, Oregon mounted one of the biggest rallies in recent program history.

Amos, a freshman from Mission Viejo, Calif., posted UO’s first comeback singles win, downing Robert Stineman in the No. 6 match to level the score, 2-2. Amos dropped the first set, 4-6, but won consecutive sets, 6-3, 6-4, to notch the first three-set win of his young career. Amos improves to 23-5 overall and 19-3 in dual play, improving to fourth-best on Oregon’s chart for most singles wins in a season.

Farin handed upset-minded Oregon its first lead of the match, also taking a three-setter, showing heart in his first singles win in Pac-12 play. The sophomore from Brussels, Belgium, lost his first set to Daniel Ho, 4-6, in No. 2 singles. Farin heated up at the right time, winning the final two sets, 6-2, 6-4, to put UO ahead, 3-2. Farin improves his singles record to 18-12 this season.

With one point needed to complete the comeback, Oregon’s all-time winningest player delivered one of his most thrilling wins. Cambier rallied past Stanford’s nationally ranked John Morrissey, 4-6, 6-4, 6-2, clinching the Ducks’ massive rally. Cambier improves to 23-9 on the season, joining Amos with the fourth-most winningest singles season in UO history.

Sophomore Daan Maasland also gave Oregon an opportunity to clinch, leading 5-4 in his third set before the match was left unfinished following Cambier’s win. The Geldrop, Netherlands, native took his first set, 7-5, against Stanford’s Trey Strobel. Maasland dropped the second set, 4-6, but assumed control of the third set to provide UO insurance.

Junior Daniel Sardu posted Oregon’s first singles win in the No. 4 match, leveling the score at 1-1 in the first completed singles match of the day. Sardu defeated Nolan Paige for the second time this season, 6-3, 6-4, and improved his record to 16-9 this season. Sardu improves to seventh in Oregon all-time singles wins list with 57.

Oregon won the doubles point against Stanford in the regular season, but the Cardinal took a 1-0 lead in today’s battle. Jamin Ball and Robert Morrissey downed UO’s Daan Maasland and Joey Swaysland, 8-4, in the No. 2 match.

The Ducks pulled level courtesy of Cambier and Farin’s No. 1 doubles victory. The duo defeated Robert Stineman and Daniel Ho, 8-4, and improved to 23-6 overall. The Belgium natives’ win tally ranks tied for second in UO’s doubles wins in a season list.

Stanford clinched the doubles point behind Yale Goldberg and Trey Strobel’s 8-6 win over junior Daniel Sardu and freshman Jayson Amos in No. 3 doubles. Sardu and Amos close the season with a 16-8 record in No. 3 doubles. As a team, Oregon posted an impressive 43-17 (.717) doubles record this spring, winning the doubles point in 19-of-24 matches.

“Coming into the tournament, we had backed ourselves into a corner,” said Schyllander. “To open with two straight wins here is a credit to the team’s effort. Now, we’ll need to recharge quickly for a very talented UCLA team.”

The Ducks will meet second-seeded and fifth-ranked UCLA in the semifinals. The Bruins (20-3, 6-1) finished runner-up in Pac-12 standings this season and are yet to play in the Pac-12 Championship after receiving byes into the semifinals. The Oregon-UCLA semifinal match will begin at 3 p.m. (PT), Friday at Libbey Park. Top-seeded USC takes on third-seeded California in the other semifinal match, which will get underway at noon.
