Edwards (back) was reinstated from the 10-day injured list and is starting at shortstop and batting leadoff Tuesday against the Nationals.
The 25-year-old suffered the back injury Aug. 23 against the Cubs and is rejoining the Marlins after a minimum-length stay on the IL. Edwards has a .349/.428/.436 slash line with one homer, 22 steals, 17 RBI and 25 runs in 47 games this season and should serve as Miami's starting shortstop and leadoff man for the stretch run.
