Prospect Potent Potables - 7/16

• The Chicago White Sox have promoted their first round pick from this year, LHP Chris Sale, to Triple-A, reports Scott Merkin of MLB.com.  The Sox hoping to get a good look at Sale to gauge the possibility of him being a part of their bullpen down the stretch.
• John Lamb extended his streak of not allowing an earned run to 30 innings on Thursday night, as the Royals' pitcher continues to rise up the prospect lists.  Also streaking is Phillies OF Jiwan James who has extended his hit-streak to 22 games.
• Dustin Ackley's Triple-A career got off on the right foot when the Mariners' prospect homered in his first at-bat, but the rest of his night was not as successful and he ended up with a 1-5 performance in his debut.
• The success Jordan Lyles is having this season can be attributed to an improved curveball and a more consistent cutter, says Ben Badler of Baseball America.  The improved arsenal has allowed the Houston prospect to dominate Double-A hitters despite being in his teens.  Fellow Astro pitcher Ross Seaton isn't having as much success trying to adjust, notes Zachary Levine of the Houston Chronicle.  Also struggling is Jiovanni Mier, the team's top pick in 2009, but the 19-year-old shortstop appears to have benefited from a drop in the lineup, says Bill Ballew for MLB.com.
• Jose Iglesias and Adeiny Hechavarria have a lot more in common than just being Cuban shortstops, and their friendship dates back a long way, reports Morgan Campbell of the Toronto Star.
