This weekend, USC stole two road wins to move to 20-4 (7-4 Pac-12) on the season.
The wins against UW and WSU represented the first road sweep of head coach Andy Enfield's tenure.
Before this weekend, the Trojans' last road sweep came during the 2010-11 season against the Bay Area teams.
USC's win over WSU on Feb. 4 marked the earliest date in program history that the Trojans have reached 20 wins.
The return of sophomore Bennie Boatwright was key in USC nabbing wins 19 and 20. Out since Nov. 30 with a knee injury, Boatwright saw his first action in two months against the Huskies on Thursday.
The forward showed no signs of rust, tying his career high with 23 points. Against WSU, he added another 13.
Boatwright's big game provided the spark USC needed on Thursday.
Down 10 at the half, the Trojans came out swinging in the final 20 minutes to earn their 11th comeback of the year after trailing by 9 points or more.
USC is now riding a four-game conference win streak (its longest since 2013) into this week's home stand against Oregon State and Oregon.
The Trojans are looking to sweep the Beavers this season and earn their third win over a Top 25 team when the Ducks come to town.
