1. No. 3 UCLA (28-8, 14-4)
The Bruins have kept it rolling with back-to-back series wins against their in-state rivals USC and California. UCLA still leads the Pac-12 in team ERA (2.18) and strikeouts (333).
2. No. 5 Arizona State (25-11, 13-5)
Arizona State made the jump over USC after winning their series against Utah and Arizona. The Sun Devils continue to impress on offense with the No. 2 team batting average in the conference (.300), but have seen their opposing batting average dip to No. 8 in the conference at .258.
3. No. 10 USC (29-10, 10-5)
USC struggled to generate enough offense to top UCLA, but scored 35 runs in three games against Oregon last weekend to retain their spot amongst the conference’s elite teams. Like their ranking, the Trojans are No. 3 in the Pac-12 in team batting average (.299) and team ERA (3.00).
4. California (23-13, 10-8)
Despite losing two of three against both UCLA and Stanford, Cal has maintained a solid 2.93 team ERA and still leads the conference in home runs with 34. With a pair of big series against Arizona and Arizona State coming up, the Golden Bears still have a lot of room to improve their conference rank before the end of the season.
5. Arizona (24-13, 9-9)
The conference’s top offense hit a brick wall in Corvallis last weekend as the Wildcats could only muster four runs in three games against the Beavers. Despite maintaining its .313 team batting average, Arizona has now dropped seven of its last nine games and has slipped out of each of the top 25 polls.
6. Oregon State (25-12, 8-7)
While the Beavers’ .416 slugging percentage hasn’t translated to runs, Oregon State is still one of the most formidable teams in the conference with capable hitters and pitchers. The Beavers host USC this weekend with a chance to leapfrog Arizona in the conference rankings.
7. Washington (21-16, 7-11)
The Huskies have regressed over the past few weeks and lost two-of-three against Washington State and Arizona State in back-to-back weekends. Washington is right in the middle of the conference with a .263 team batting average and 3.07 team ERA.
8. Oregon (23-18, 5-10)
The Ducks looked like they turned a corner in their series win over Oregon State, but fell back on old habits in a messy series with USC. The Ducks’ offense is third-to-last in the conference with a .253 batting average, while their pitching staff has watched their ERA balloon to 3.87 after giving up a plethora of runs to USC last weekend.
9. Washington State (21-18, 5-10)
10. Utah (13-22, 5-10)
11. Stanford (16-21, 4-11)
