The league issued the following statement:
As evidenced by our Joint Domestic Violence Policy, Major League Baseball understands the seriousness of the issues surrounding domestic violence, and our Policy explicitly recognizes the harm resulting from such acts. Consistent with the terms of this policy, the Commissioner's Office already has begun its investigation into the facts and circumstances. Any action taken by the Commissioner's Office in this matter will be wholly in according with this Policy.
Commissioner Rob Manfred briefly addressed the Reyes incident Tuesday at the GM meetings, saying it's "obviously" an issue of concern to the league. He also said there's no timeline for the duration of the investigation at this point, and reiterated any punishment will fall under the new domestic violence policy.
"This will be the first test. I think it will stand the test," Manfred added.
The Rockies also addressed the situation early Tuesday morning, stating they'll look into the allegations in accordance with MLB's Joint Domestic Violence, Sexual Assault and Child Abuse Policy.
Under MLB's domestic violence policy, players can be suspended with pay while legal charges are pending in "exceptional cases."
Reyes is set to make $22 million next season, and under contract through the 2017 season with a club option for 2018.
