I pulled up the LSU ticket website to see what you were running across, and it says "Standing Room Only - Grandstand." Their grandstand had a concourse at the top where I suppose you can stand, much like the concourse at Olsen.
If you want a real seat, you can buy seats for a variety of prices on StubHub, although the prices aren't cheap. There are some folks selling tickets outside the park, but I don't know what that market is really like, and what kind of success you will have in A&M gear. If you want to hedge your bets, you might buy those SRO tickets, then see if you can pick up a bargain for a real seat at the ballpark.
I went ahead and got tickets on StubHub a few weeks ago because I don't like to gamble.
