Nathan (elbow) has not begun throwing but is hoping to return before the All Star break, Anthony Fenech of the Detroit Free Press reports.

EDGE Analysis

Nathan underwent Tommy John surgery early in the season, but the 40-year-old is attempting to rehab his way back rather than call it a career. He'll become a free agent if the Tigers decline his option for 2016 as expected, but he could help out a bullpen in the second half of the season wherever he lands.
