According to court records, Olivera was convicted Thursday in District Court in Arlington, Virginia, and sentenced to 10 days in jail.
Arlington police were called April 13 to the Ritz-Carlton Hotel in Pentagon City, where a woman with visible bruises reported that Olivera had assaulted her. Police said Olivera and the woman are acquainted. Olivera was playing for the Braves.
Major League Baseball put Olivera on an 82-game suspension under the sport's domestic violence policy.
On Aug. 2, Atlanta traded Olivera to the San Diego Padres. The Padres placed him on unconditional release waivers eight days later.
