I was at Target Field 4/20 and didn't notice any problems as far as lines go for the men's restroom. I didn't realize until after I'd finished there was an additional set of urinals in part II of the room, but I didn't have a line to wait it in. I was in and out in and back to my seat in less than a 1/3 of an inning. Before the game might be an issue as people are slow to get to their seats.
Totally a Billy Beane move. Yes, it's a high priced guy, but he's also a big poker chip they can trade at the deadline if it doesn't work out, or can let go in free agency for two high draft picks next year.
