Jayson Starks' most recent ESPN column had a nice blurb about Tyler Yates:

Penmanship in Atlanta: One cardinal rule we've learned over the years is: When the Braves trade away a pitcher, never question it. But other people out there are already second-guessing their decision to deal away reliever Tyler Yates to Pittsburgh at the end of spring training.

"I think their bullpen is going to have trouble," said one scout. "I love [Rafael] Soriano as a set-up guy. But as a closer, I think he's just middle-of-the-pack. … [Peter] Moylan is tough on right-handers, but I don't think he can get left-handers out. … Guys like [Blaine] Boyer and [Chris] Resop have great arms, but they walk too many people and they're up in the zone a lot. And [Manny] Acosta is the same way. … So for me, you take that whole set-up crew, and Tyler Yates is better than all of them."
