Saupold (groin) was activated from the disabled list Monday, Anthony French of the Detroit Free Press reports.
After finishing up a rehab assignment at Triple-A Toledo last week, Saupold will return to the Tigers' bullpen, where he holds an ugly 10.80 ERA through five appearances on the year. Saupold has allowed 13 hits and eight earned runs while striking out eight and walking three over 6.2 innings.
