According to MLBTradeRumors and other sources, the Chicago White Sox have claimed Pirates lefthanded reliever Daniel Moskos off waivers, ending a disappointing tenure in the Pirates organization. Moskos was the fourth overall pick in the 2007 draft, taken by then-GM Dave Littlefield, one pick ahead of Matt Wieters. The two players will forever be linked in Pirates lore.
Moskos had a brief run of success with the team last season, but he didn't make an impact this year even though the Pirates had a stated desire to add a second lefty to the bullpen. In late June when the organization needed to create a roster spot on the 40-man, Moskos was a mildly surprising choice. He clearly hadn't shown enough in his repertoire, so the Pirates deemed him expendable, electing to keep lefty Doug Slaten (since DFA'd) and righty reliever Daniel McCutchen.
The White Sox have optioned Moskos to their AAA affiliate in Charlotte.
