Lefty reliever Zach Kroenke has cleared waivers and been optioned to Triple-A Reno by the Diamondbacks, according to MLB.com's Steve Gilbert. Arizona selected Kroenke from the Yankees with the sixth overall pick in December's Rule 5 Draft.
Since this was Kroenke's second time through the process (the Marlins selected him in last year's Rule 5 Draft), he had the right to declare free agency if someone claimed him. As Jack Magruder of FoxSportsArizona.com explains, New York was told that Kroenke would elect to become a free agent if they wanted to take him back, so they never bothered to put a claim in. ESPN's Keith Law confirmed with Kroenke's agent that the Diamondbacks' chose to keep him on the 40-man roster even though he cleared waivers.
The 26-year-old Kroenke was the Yankees' fifth round pick in the 2005 draft, and posted a 1.99 ERA with a 6.8 K/9 and a 3.7 BB/9 in 72.1 Triple-A innings last year. He has held lefties to a .256 batting average during his minor league career.
