Prospects are fascinating. Some make it to the big leagues, some break your heart, some turn into stars. Let's take a look at some notes on several players down on the farm, starting with arguably the biggest news of the day coming from the Washington Nationals...

• ESPN's Keith Law is reporting the Nationals top pick in this year's draft, right-handed pitcher Lucas Giolito, reinjured his elbow and will visit Dr. Lewis Yocum this week. It appears the No. 16 pick suffered the injury during his first professional outing last Tuesday.
• The No. 19 overall pick in this past year's draft, St. Louis Cardinals right-handed pitcher Michael Wacha, impressed in his Double-A debut, writes Kary Booher of the News-Leader. Wacha tossed three scoreless innings, striking out six and only walking one. The team's Double-A manager Mike Shildt offered some insight, as well.
• A scout spoke with a Josh Norris of The Trentonian's Thunder, offering ton of insight on a bunch of Yankees prospects in Double-A and the lower level of the minor leagues. The list includes Gary Sanchez, Mason Williams and Slade Heathcott.
• Kevin Goldstein of Baseball Prospectus released his "Monday Morning Ten Pack" with notes on ten interesting prospects, including Trevor Bauer and Miguel Sano. You can read half of it for free, and the other requires a subscription.
