Making Moves - 7/21

• Anthony Slama may not be the youngest prospect to come along, but he has been among the most productive at what the Twins have asked him to do, and they've finally asked him to do it in Minnesota, reports Jocelyn Syrstad of MLB.com.
• After destroying the Sally League, the Astros decided to jump J.D. Martinez all the way to Double-A, says Zachary Levine of the Houston Chronicle.
• Tanner Scheppers is back in the bullpen in Triple-A after an unimpressive performance as a starter, reports Jeff Wilson of the Fort Worth Star-Telegram.  The move, however, has nothing to do with being roughed up as a starter, but is simply to prep him for a bullpen role in Texas later this season.
• Andrew Carpenter was promoted to the majors to replace the struggling Kyle Kendrick, says Phuture Phillies.com, and was forced into action immediately on Tuesday night when Phillies' starter Jamie Moyer had to leave the game after one inning.
• We have an official timetable for Drew Cumberland's knee injury - 6-to-8 weeks, according to Corey Brock of MLB.com, for what is officially being called a severe knee laceration.
