We're sure this happens all the time, but it's still funny when Major League Baseball accidentally slips and posts it. Last night and up until early this morning, you could buy this sweatshirt from MLB.com, prominently featuring the upcoming World Series matchup between the Detroit Tigers and the New York Mets.

We went searching around for other merchandise — we were hoping they'd really screw up and we could grab an A's-Mets legwarmer or something — but they've cleaned up the mess now. We wonder if they actually printed the shirts, or if they just made the graphic for the Web site.

That's a really ugly shirt, by the way.
