The Major League Baseball Players Association filed a grievance against the Astros on Thursday for trying to manipulate the signing of top pick Brady Aiken.

The Major League Baseball Players Association filed a grievance against the Astros on Thursday for trying to manipulate the signing of No. 1 draft pick Brady Aiken, Fox Sports' Ken Rosenthal confirmed after it was first reported by former New York Times reporter Murray Chass.

Aiken and the Astros failed to reach an agreement by last Friday's deadline after team doctors reportedly found an abnormality in Aiken's throwing elbow in his post-draft physical. 

The grievance also involved the handling of two of the players the Astros selected later in the draft.

MLBPA director of communications Greg Bouris declined to comment about the alleged transgressions.

“When things are written that we did things unethically or tried to manipulate something, it’s frustrating to read, because it’s not true,” Astros GM Jeff Luhnow said earlier this week, according to the Houston Chronicle's Evan Drellich. “It’s hard to convince people just by saying it’s not true, but it’s not. And that’s probably been the hardest part. But again, you know, you have to have a thick skin to be in this business. That doesn’t mean you don’t take feedback, because we do, we listen to everything everybody says, and read everything people write and we take it into consideration. But at the same time, ultimately, we’re doing what we think is in the best interests of the organization.”
