Two weeks after being released by Oakland, Jim Johnson is headed back to the big leagues. The Tigers announced they will call up the former O's and A's closer from Triple-A Toledo and put him in their bullpen Sunday, trying to add a veteran arm to a late-inning staff that has had its struggles.

Johnson is not expected to reprise the closer's role that earned him back-to-back 50-save seasons the past two years in Baltimore. For now, at least, the Tigers will try to figure out how much Johnson can help them, and where his pitching stands after a rough half-season in Oakland.

The A's released Johnson on Aug. 1 after his fall from Oakland's closer at season's start to little-used reliever at the back of the bullpen by July. It was a stunning turn after Johnson recorded 51- and 50-save seasons in Baltimore over the previous two years, leading the Majors both times.
