Oregon dropped the polls after three run-rule nonconference wins.
The Ducks (25-11, 5-7 Pac-12) are No. 18 with 202 points in the USA Softball poll and No. 19 with 239 points in the NFCA poll after drubbing Montana and Lindenwood twice.
That’s down from No. 16 with 230 points in the USA Softball poll and down a spot from No. 18 but with 237 points in the coaches poll last week.
Oregon travels to Arizona State for a three-game series starting at 6 p.m. Friday.
