Relief pitcher Bruce Sutter of the Atlanta Braves is returning home from the team’s six-game trip for tests to determine the source of shoulder pain that may have brought his season to a premature end.

Sutter is to have an arthrogram, a process in which dye is injected into a joint to detect injuries that would normally not show up on X-rays.

Meanwhile, Manager Bobby Wine said that Rick Mahler, out since Sept. 6 with a broken finger, is ready to return to the rotation.

Wine said that Mahler (17-14) will probably start Wednesday against the Cincinnati Reds.
