Prospect Potent Potables - 7/6

• Jeremy Jeffress is determined to stay clean, reports Tom Haudricourt of the Milwaukee Journal-Sentinel, and is on the comeback trail as a reliever, a role that ultimately suits his arsenal of pitches better than starting ever did.  He's also been added to the Brewers' 40-man roster, which means he no longer receive a lifetime ban if he's caught with marijuana again.
• Blake Beavan has transformed from a fire-balling Texan into a strike-throwing innings-eater the Rangers may be able to rely on in their rotation very soon, reports Drew Davison of the Fort-Worth Star-Telegram.
• Michael Pineda has made the transition to Triple-A without issues thus far, and according to Mike McCall of MLB.com, could be in Seattle before too long.  Speculating further, it does seem that Pineda has little left to prove in the minors and is at the very least a realistic candidate to assume the open rotation spot that will eventually be vacated when Cliff Lee moves on.
• If the Yankees' farm system suddenly seems to be rich with pitching prospects, it's due in large part to the resurgence of prospects Andrew Brackman and Dellin Betances, says Bubba Brown for Baseball America.
• Freddie Freeman has rebounded from a horrible month of April that left many questioning the Braves' decision to have their future 1B make the jump to Triple-A despite just 41 games at the previous level, notes John Wagner for MLB.com.
• Kyle Drabek feels like he's ready to move up from Double-A, reports Morgan Campbell of the Toronto Star, and cites his recent no-hitter as verification.  He's probably right, and despite the Blue Jays' logjam of arms at the higher levels, he's logged plenty of innings in Double-A and needs to be pushed further.
• Mike Moustakas is making his case for minor league player of the year, but it's nights like he had on Monday that make the argument for him, to which Rustin Dodd of the Kansas City Star and John Parker of MLB.com can both attest.
