Miller prematurely left Wednesday's Spring Training contest after a line-drive hit his right wrist. The injury was initially thought to be a bruise.
Since Aroldis Chapman will open the season serving a suspension, Miller was expected to open the year as New York's closer. He had success in that role last season, pitching to a 2.04 ERA and 2.16 FIP to complement 36 saves over 61.2 innings last season.
With Opening Day less than a week away, Miller could open the season on the disabled list. However, the injury might not be that extreme.
If New York's top two closing options are unavailable to open the year, the team still has an experienced arm to turn to.
Dellin Betances saved nine contests last season to complement a 1.50 ERA over 84.0 innings. He will likely be the Yankees' closer if Miller's injury is more serious than it appears to be.
When the Yankees acquired Chapman, the expectation was the club would try and trade either Betances or Miller. That didn't end up happening, which now could prove to be beneficial for the Yankees.
