College baseball rankings: Ole Miss takes the top spot after a crazy opening week

After a tumultuous opening weekend in college baseball, Ole Miss took took over the No. 1 spot in the D1Baseball Top 25 rankings for the first time in the seven-year history of the rankings. The preseason No. 6 Rebels went 3-0 at the State Farm College Baseball Showdown with wins over three Big 12 opponents who ranked in the preseason Top 25: then-No. 3 Texas Tech, then-No. 9 Texas and then-No. 10 TCU.

Arkansas also made a big jump on the strength of its own 3-0 showing in Arlington, with three wins against the same three opponents Ole Miss defeated. The Razorbacks vaulted six spots from No. 8 to No. 2, matching their highest ranking ever in the D1Baseball Top 25, last achieved in the final ranking of the 2018 season.

Vanderbilt and Louisville moved up one spot apiece to Nos. 3 and 4, respectively, and Mississippi State moved up two spots to No. 5 following a 2-1 showing in Arlington.

Miami made the biggest jump of the week, from No. 21 to No. 6, after going on the road and taking two of three from preseason No. 1 Florida, which fell six spots to No. 7. Preseason No. 2 UCLA also tumbled six spots to No. 8 after dropping a home series to San Francisco. And preseason No. 3 Texas Tech fell to No. 10 after going 0-3 in Arlington. UC Santa Barbara moved up two spots to No. 9.

Other teams that took tumbles in the rankings included TCU (down four spots to No. 14), Texas (down 10 spots to No. 19), and West Virginia (down nine spots to No. 23). The Mountaineers went 2-2 against Georgia State, but their fall in the rankings also reflects a recalibration in light of the news that key weekend starter Ryan Bergert will miss the season due to injury — a development that was released after our preseason Top 25 was published.
