Hall of Fame pitcher Pedro Martinez said on social media that several of his family members were inside the nightclub that collapsed in the Dominican Republic early Tuesday.
"I still have family members that are still in the rubbles, and we don't know what happened to them," Martinez said in a video posted to Instagram on Tuesday night.
At least 124 people have been killed with hundreds more injured from the collapse at the Jet Set nightclub in Santo Domingo that occurred around 1 a.m. Tuesday.
Former World Series champion Octavio Dotel and former MLB player Tony Blanco were among the dead, as was Nelsy Cruz, the governor of the Monte Cristi province in the country and sister of seven-time MLB All-Star Nelson Cruz.
