Colorado women’s volleyball put 16 serves out of play Thursday evening as it fell to Southern Cal 3-1 (24-26, 25-18, 25-20, 25-22).

The Buffaloes (8-11 Pac-12) 16 service errors is the most since playing against the Trojans (6-8 Pac-12) back in 2017 in California. Colorado battled back to steal the first set, but seven service errors in the third set kept CU from taking the 2-1 advantage.

Colorado outhit USC with a .234 hitting percentage as Sterling Parker and Leah Clayton went for .321 and .286 with a dozen kills each, respectfully. Clayton finished with a double-double with 10 digs while Alexia Kuehl had seven kills and Jill Schneggenburger had eight.

CU switched back to the 5-1 in set four, allowing Brynna DeLuzio to return to libero and put up a team-best 15 digs. Jenna Ewert had 24 assists and 11 digs as she recorded her 34th career double-double, putting her 14th in CU history. Kuehl had a match-high five blocks.

The serving game was the biggest factor in the game as CU not only dished out 16 free points but also failed to record an ace for just the second time this season. USC also benefitted from four players with double-digit kills, led by Brooke Botkin’s 15 to go with her 10 digs. Kalen Owes put down 13 while Emilia Weske and Aleksandra Gryka each had 11.

The Buffs have never won in Pasadena as a program but closes the season Saturday at 2 p.m. in the Galen Center against USC.
