Eyes on Rule 5

Chris Kline at Baseball America.com has a look at the top players available in the Rule 5 draft.

Would I mention it if there weren't a few former Rattlers in the article?

Luis Valbuena, 2b, Mariners
Outstanding defender with interesting lefty bat

Marwin Vega, rhp, Mariners
Three average pitches with a lively 91-93 mph fastball

What the heck is the Rule 5 draft? This link to a 1995 BA article is still a good explanation.
