Sure, picking up Valencia was an okay move. The thing is that without that absurd BABIP and essentially getting lucky, Valencia is a really marginal player. First, he's the wrong side of a platoon. No matter what you do, the guy is going to take many of his ABs against RHP. It's inevitable and you can basically write off any ABs he takes after the sixth inning. There is no reason he should ever face a lefty out of the bullpen. Ever. Second, he's an awful defender at third. Will it work out for the Royals? Sure, Valencia may get lucky and post an absurd BABIP against lefties again. Is it likely that it will work out? No, probably not. I'm still floored that Duquette was able to get anything for a guy with 170 PAs in 2013, much less what looks to be a decent fourth outfielder. Every single stat line in Valencia's 2013 SSS screams regression in a big, bad way. Well, except for his BABIP against RHP. But that's not exactly the stat line you want to see up on the upswing in a platoon player. Also, it should be noted that the Orioles didn't do a particularly good job of protecting Valencia against righties, which puts into the question their "setting him up to succeed". Valencia had 102 PAs against lefties, 68 PAs against righties. Sure, it's hard to protect a RHB platoon against righties but at a glance, it doesn't look like the Orioles even tried that hard to do it. 68 PAs is 40% of his total PAs in 2013. Again, Duquette made a marginal move and got really lucky with it. The smartest thing he did was recognize that luck and flipped that player for something before he regressed.
