Sutton, who was designated for assignment by the Rays earlier this week after hitting .271/.315/.354 for the club in 18 games, joins the Pirates organization for the second time this season.
Signed to a minor league deal with the Braves prior to the season, Sutton was traded to the Pirates on May 20 then flipped to the Rays the following day for a player to be named later. Struggling to get production at the hot corner, the Rays used Sutton as part of the tag team they have employed at third base in Evan Longoria's absence.
A switch-hitter, Sutton has a career .261/.320/.391 line in parts of four big league seasons. With his return to the Pirates, Sutton has now played for seven organizations in the last four years, reaching the majors with five of those squads.
The Pirates have transferred pitcher Charlie Morton from the 15-day to the 60-day DL to make room for Sutton on the 40-man roster. A corresponding move for the 25-man roster has yet to be made.
