I wouldn't say it was fishy, necessarily.
In a 10-2 game, relievers don't come into the game and nibble at the corners. Their job is to throw strikes and if the hitters hit it, so be it.
Don't walk guys, throw your best pitch, and let's get out of here as painlessly as possible.
Plus, in Rodriguez, you have a young guy who is probably thinking "I just smoked one by Bonds, I can do it again", then he doesn't throw it exactly where he wants it (ie it's not quite as high and too much out over the plate), and buh-bye.
As a baseball bettor, you should also know how many times "meaningless" homers bite totals players

This sort of things happens all the time, it just happened on a much more exposed scope than usual.
