Draft Notes: Appel, Gray, Shipley, Manaea, Stanek

The Astros, Cubs, and Rockies have the first three picks in the 2013 amateur draft, which takes place Thursday, June 6th.  Draft gurus expect college righties Mark Appel and Jonathan Gray and college third baseman Kris Bryant to go within those first three picks, though the order seems tough to pin down at this point.  The latest on the draft:

• Conor Glassey of Baseball America takes a look at the age spectrum among this year's BA Top 250 by splitting the list into high school and college players and examining the youngest and oldest in each group.
• Baseball America's Jim Callis asked four "top-level scouting executives" whether they preferred Appel or Gray.  Three of them chose Appel, though it was interesting to hear that two of them questioned his makeup.
• MLB.com's Jonathan Mayo talked to Nevada righty Braden Shipley, a converted shortstop.  ESPN's Keith Law ranks Shipley the No. 6 talent in the draft, and predicted the Marlins will indeed take him in that sixth spot.  Baseball America ranks him eighth, and predicted he'd go fifth to the Indians.  Mayo went with eighth to the Royals.
• Mayo also writes that Shipley has elevated his stock thanks to consistent performance this season, while Indiana State lefty Sean Manaea and Arkansas right-hander Ryne Stanek have seen their stocks fall. Manaea has been bothered by a hip issue that has led to diminished results, while Stanek has had an up-and-down season as well. A scouting director told Mayo that he thinks Stanek will be the third pitcher selected in the draft. The upcoming conference tournaments will serve as a showcase for these college arms to gain some last-minute draft helium.
