For the third time this week, the Red Sox have added an infielder to their organization.

The Red Sox on Friday claimed Tsung-Che Cheng on waivers from the Washington Nationals. Cheng, from Taiwan, had been in the Pittsburgh Pirates organization for a number of years and made his major league debut last season, appearing in three games.

He spent much of last year at Triple A Indianapolis where he slashed .209/.307/.271 with one homer and 18 stolen bases in 107 games.

Since the end of the season, Cheng, 24 has been on the waiver merry-go-round, claimed on waivers by four different teams. In early January, he was claimed by the Tampa Bay. Weeks later, the New York Mets claimed him, and late last month, so did the Nationals.

Over the course of his career, the lefthanded-hitting Cheng has played shortstop, second base and third base. He spent five seasons in the minors before making his big league debut last April.

Cheng is the third infielder acquired by the Red Sox in the past week. They signed Isiah Kiner-Falefa to a major league deal earlier this week, and on Thursday night, the club agreed to terms with veteran infielder Brendan Rodgers on a minor league deal.

By claiming Cheng, the Red Sox are now at 40 on their 40-man roster with spring training set to start next week.
