In the table below, I've added PerfectGame.org to the mix for a six-ranking composite.
Oregon State remained No. 1 in the rankings for the fourth week. The Beavers are No. 1 and Louisville is No. 2 in all six rankings. North Carolina replaced TCU as No. 3.
Clemson remained fourth in the composite rankings. South Carolina plummeted from 10th to 22nd after going 1-3 last week. USC dropped out of the Baseball America ratings for the first time this season.
There are eight SEC teams and five ACC teams in the composite Top 25 ranking. The +/- represents rise or fall from last week's composite rankings.
