Hector Olivera has been arrested after a woman accused him of assault at a hotel outside Washington.
Police in Arlington, Virginia, said a woman called them at 6:51 a.m. ET. When police arrived, they found a woman with visible bruises claiming she had been assaulted by the Atlanta Braves outfielder.
Olivera was taken into custody but has not been formally charged.
Police said Olivera, 31, and the woman know each other, but do not know the nature of their relationship.
"We are extremely disappointed and troubled to learn of the allegations involving Hector Olivera," the Braves said in a statement. "We will continue to gather information and will address this matter appropriately as we determine the facts."
Major League Baseball has placed Olivera on administrative leave, effective immediately.
