Cardinals GM John Mozeliak said Sunday that Edman (wrist) will need to be ready to play all his defensive positions and have his proper timing at the plate before completing his minor-league rehab assignment and being activated from the 60-day injured list, Wilson Truong of KMOX News Radio reports.

The 29-year-old began a rehab assignment with Double-A Springfield last week but has exclusively played at designated hitter in his first four games, and Edman will need to see significant action in the field before joining the Cardinals. He has yet to see major-league action this season while recovering from offseason wrist surgery, and his rehab has been bumpy due to setbacks and other minor injuries. Given the length of his absence, Edman will likely need a couple more weeks in the minors to get up to speed, putting him on track to return in late July or early August.
