It's probably on Youtube where he, playing in the minors, threw his bat at the home plate umpire.
I would rather go with McLouth and Reimold than sign Young. He can hit but that's about it, and if he isn't getting the playing time, you don't know exactly what he might do. I suspect that the O's will have some sort of platoon with McLouth, Reimold and Betemit, with Reimold getting bats against lefties and giving a day off to McLouth every so often. And if Chris Davis struggles, you might see Reimold play some first base, too.
I know a lot of folks seem to be upset with the Orioles for losing Reynolds and not really replacing him on a 1 to 1 basis. But if guys like Markakis, Reimold and Roberts can stay healthy, and if AJ, Davis, Wieters and Machado can improve (except for BRob being healthy, none of these is a reach), I don't think the overall offense is going to suffer in terms of run scored.
But as the Earl used to say,"It all comes down to what happens on that little hump in the middle of the infield." If you tell me the offense will be better and the pitching will be worse, I'm not happy. But if you predict the pitching will be better and the offense worse, I can live with that. Good pitching gives you a chance to win, bad or mediocre pitching little chance.
