Juan Rivera signs

At a pretty reasonable rate too, 12.75 million over 3 years. Here's his projection page: Juan "Johnny Rivers" Rivera

He's +5 runs on offense, -7.5 for position adjustment, so he's barely below average before defense. He's not that fast, and while his UZR has been about average in left field, it is below average in right. For his career he's about -5 per season. Since he missed most of 2007 and has not played regularly, his playing time projection is not very good either, but add it all up and choose the "poor" defensive category, and he's 1.1 wins above replacement or worth 4.8 million - looks like a decent bargain.

But his throwing arm is very good, so he should pick up a few runs for that. Maybe not enough to move him into the average category, but somewhere in between. He also may have some upside in playing time. Rivera does not seem to be an injury prone player, like Kendrick has been. He just had a very bad freak injury. That was two years ago, so he should be fully recovered.

I see the Angels made at least a decent signing, and also one with some serious possible upside. If Vlad Guerrero continues to see more time at DH, then having Rivera around is much better than a generic left fielder, since his arm is more than enough for right. Welcome back Johnny Rivers!
