Segura (ankle) is expected to be activated from the disabled list Thursday, Bob Dutton of The Tacoma News Tribune reports.
Wednesday was the original target date, but the Mariners will hold off one day just to be safe. He began a rehab assignment Monday as the Triple-A affiliate's designated hitter and is expected to play shortstop Tuesday. As long as all goes well with that, the young shortstop should resume his normal position with the major-league club Thursday, moving Taylor Motter to the bench.
