Chapman (Achilles) will begin a rehab assignment at Double-A Somerset on Friday.
Chapman has been on the injured list for a month but has now been cleared to return to game action at the Double-A level. He'll likely be able to rejoin the Yankees following a brief rehab assignment, so it wouldn't be surprising to see him activated early next week. Once Chapman is deemed fully healthy, it's certainly possible that Clay Holmes maintains a share of the closer role, as Holmes has converted 10 of his last 11 save chances while posting a 0.59 ERA and 0.65 WHIP in 15.1 innings over his last 14 appearances.
