The Pirates claimed righty Angel Sanchez off waivers from the White Sox, tweets Bob Nightengale of USA Today. Nightengale adds that the Bucs designated righty Josh Wall for assignment to open a spot on the 40-man roster for Sanchez.

The Rays claimed Sanchez off waivers from the Marlins in June, and then the White Sox claimed him earlier this month. The 24-year-old has a 6.57 ERA, 5.5 K/9, 2.8 BB/9, and 0.71 HR/9 in 89 innings at Double-A and High-A this year. Baseball America ranked him 16th among Marlins prospects prior to the season, noting a live 92-95 mile per hour fastball. The Marlins had acquired him from the Dodgers last July as part of the Ricky Nolasco trade.

Wall, 27, was also sent to the Marlins in the Nolasco deal last summer. He was claimed off waivers by the Angels in October, then claimed by the Pirates in May. He has a 3.55 ERA, 9.0 K/9, and 3.8 BB/9 in 33 Triple-A relief innings this year.
