Vlad Guerrero can still hit the ball. His last great .950 year was 2007, but since then he's averaged about .300/.350/.500. He doesn't appear to be about to crash and burn. He's basically a DH; could play ten or twenty games in LF in an emergency. The last time he tried to play the field regularly, in 2009, he got hurt and missed about a third of the season. Lesson: Don't play him in the field very much. This would be a good signing if you're an AL contender with some money to spend. I'd even think about getting a team option year if I thought my team had a multi-year playoff window. Vlad is going to hit the ball, and an .850 OPS looks great in the cleanup or fifth spots. But the Orioles are not a contender and they are actually blocking a younger player by adding Vlad, so it's a very bad deal for them, since they're going nowhere. He would be a thoroughly bad signing for the Royals, since the last thing we need is an aging DH. However, a Vlad-type player would be perfect to have around if the Royals break in their prospects and then go for the playoffs in 2014. He'd be worth 2.5-3 WAR per year.
