The Red Sox claimed Cheng off waivers from the Nationals on Friday, Gabrielle Starr of the Boston Herald reports.
It's the fifth organization Cheng has been in this offseason, as he has been bouncing around all winter via waivers. The 24-year-old went hitless in seven plate appearances during a cup of coffee in the majors and slashed only .209/.307/.271 at Triple-A Indianapolis in the Pirates organization last season, but he's known for a reliable infield glove.
