Yankees place Dustin Ackley on the disabled list with a separated shoulder; option Luis Severino to Triple-A

We have some injury updates for your thrilling, and somewhat cloudy Memorial Day. Dustin Ackley left yesterday's game after reaching base in the sixth inning. Diving back into the bag, he seemed to hurt his shoulder and was slow to get up. He was replaced by Mark Teixeira the following inning and went for tests after the game. As it turns out, Ackley separated his shoulder and will be placed on the disabled list. Teixeira, who has been dealing with a neck injury that required a cortisone shot in his neck, was forced to return to the field early. The team won't have an official backup first baseman now, but it's likely that Austin Romine, Chase Headley, and Brian McCann will be available to fill in.

In a corresponding move, Rob Refsnyder has rejoined the MLB team, but probably won't be a candidate to play any first base. He will probably remain on the bench, but could see action in right field and at second base. If there was any time where Nick Swisher would be considered a useful major league addition, this might be the time, but the Yankees not bringing him up should be telling. It feels like we have been talking about depth at first base since Greg Bird underwent surgery.

The Yankees have also decided to option Luis Severino to Triple-A after activating him from the disabled list. The 22-year-old right-hander threw three shutout innings for High-A Tampa yesterday, and instead of bringing him back to the big leagues, the Yankees feel like he needs to work on some things. It's not like the decision is surprising, but with Michael Pineda still locked into a rotation spot, it appears that Severino really is at the bottom of the totem pole right now.
