The White Sox announced that they claimed left-hander Daniel Moskos off of waivers from the Pirates and optioned him to Triple-A Charlotte. Chicago now has one open spot on its 40-man roster.
Pittsburgh selected Moskos with the fourth overall pick in the 2007 draft. He appeared in 31 games for last year's Pirates team and posted a 2.96 ERA with 4.1 K/9 and 3.3 BB/9 in 24 1/3 innings as a rookie. The 26-year-old has spent this season at Triple-A, where he has a 3.86 ERA with 7.1 K/9 and 5.1 BB/9 in 14 innings. The White Sox are known to be seeking depth for their big league bullpen.
