Seattle Mariners minor league pitcher Victor Sanchez has died, the team announced on Saturday.

Sanchez was 20 years old. He died from head injuries sustained in a boating accident in Venezuela, his home country, six weeks ago.

According to the team, Sanchez was unconscious in a medically induced coma since the accident and underwent brain surgery after sustaining a double skull fracture and brain hematoma. He had been in critical condition in a hospital.

Sanchez signed with Seattle as an international free agent when he was 16 years old. MLB.com ranked him as the team’s No. 11 prospect last year and he spent the 2014 season at Double-A Jackson, going 7-6 with a 4.19 ERA.
