I finally got my STH waiting list email earlier this morning (around 8:30 or so), clicked on the link, and there wasn't much (if anything at all) still available. The only seats that I am able to see that are still available are club level standing tickets, for over $400/ticket with taxes/fees. No thanks!
Keep in mind though that there's a good possibility that there will be visiting team ticket returns - I highly doubt a lot of Seattle fans are going to make the cross country flight for a late afternoon Sunday game (although it is a passionate and strong fanbase). I am going to keep checking the ticketmaster website frequently over the next few days for any more tickets that are released.
