The Houston Astros reinstated pitcher Roberto Osuna from the restricted list and added him to the active roster, the team announced Sunday.
In a corresponding roster move, Houston placed starting pitcher Lance McCullers Jr. on the 10-day disabled list with right elbow discomfort.
Osuna was traded July 30 from the Toronto Blue Jays in exchange for closer Ken Giles and minor league pitchers Hector Perez and David Paulino.
Osuna is coming off a 75 games suspension for violating the league's Joint Domestic Violence, Sexual Assault and Child Abuse policy, and his trade to the World Champion Astros was met with criticism.
"This was an extremely difficult decision for our organization," the Astros said in a statement. "We understood that it would cause significant debate. We are strong believers in protecting the rights of victims and remain committed to having a positive impact on our community. We will use this decision to significantly increase our support, raise awareness and influence change regarding the issues of domestic violence and abuse of any kind."
McCullers left Saturday's 14–0 victory over the Los Angeles Dodgers in the bottom of the fifth inning and will be evaluated later on Sunday.
The Astros have won four games in a row, and have a five-game lead over the Oakland Athletic in the AL West.
