College baseball Week 1: Top 25 rankings, play of the week and what to watch - ESPN

College baseball's opening weekend brought us everything we could have dreamed of. From upsets of top teams — UCLA dropped a game to UC San Diego and Louisville dropped its series to Michigan State — to historic grand slams, this season is already packing a punch. And with that, we have a new top 25, but it maybe doesn't have as many shakeups as you would think.

Despite the Bruins' loss, they keep the No. 1 spot, and the five teams behind them remained steady. But Cardinals' series loss sent them down the rankings from No. 8 to No. 15. Elsewhere, Vanderbilt and Arizona fell out of the rankings, making room for Oklahoma and West Virginia.

Here are how the entire top 25 rankings look as of Feb. 16, plus our favorite plays and what we're watching in the week to come.

Tyce Armstrong did the unthinkable in Baylor's opening weekend game and hit not one, not two, but THREE grand slams for the Bears! He is just the second player ever to accomplish such a feat, the first being Louisville's Jim LaFountain on March 24, 1976. With a start like this, what else will the senior have in store for the rest of the season?

THREE. GRAND. SLAMS.
