The Seattle Mariners have been one of the pleasant surprises in MLB this season. Expected to not do much this year in terms of competing for a postseason spot, the Mariners find themselves at 55-47 and right in the wildcard mix with the MLB Trade Deadline approaching.

It seemed obvious that if the Mariners were to do anything at the deadline it would be to add to the roster. So it comes as no surprise that some players were stunned and angered when Seattle traded their star closer Kendall Graveman to the Astros. Via Jon Heyman of MLB Network and Ryan Divish of the Seattle Times, it wasn't a great scene in the locker room after the trade.

The real salt in the wound moment with this trade is that the Mariners front office traded Graveman to a division rival, the Astros, who are in first place.

Graveman seemed shocked by the move as well.

“I didn’t see it coming,” a tear-filled Graveman said while wearing an Astros uniform. “There’s that percent, and this game’s a business. I’m speaking truth and honest. The way I felt, we were nine games over .500 over on that side and playing some pretty good ball when I was there, so it kind of takes away from the last five days, honestly, I think. We’ll see if they bounce back from it.” – Graveman via Seattle Times.

It's a puzzling move for a team that was on a vibe and playing winning baseball. Who knows what the next move for the Mariners will be.
