Top 10 fantasy baseball prospects

Eddie Butler's promotion to the Colorado Rockies last week got a bit lost in the shuffle last week, what with the recent promotion St. Louis Cardinals outfielder Oscar Taveras and Houston Astros first baseman Jon Singleton and the MLB draft, but that shouldn't have been the case. This is one of the best right-handed pitching prospects in baseball -- ranked No. 17 overall by Keith Law in his updated top 25 prospects -- with the stuff to be a true top-of-the-rotation starter for years to come.

Unfortunately for Butler, his first start for the Rockies wasn't one that he'll likely look back on with fondness, as he gave up six runs in 5 1/3 innings, allowing 10 hits and three walks while striking out just two in a 7-2 loss to the Los Angeles Dodgers on Friday.
