SAN FRANCISCO (AP) Giants star catcher Buster Posey decided to opt out of the 2020 season Friday out of health concerns for his newly adopted twin baby girls during the coronavirus pandemic.

The babies were born about eight weeks prematurely last Friday and Posey and his wife, Kristen, finalized the adoption on Thursday. Ada and Livvi are healthy but will need to spend time in neonatal intensive care and will have weakened immune systems for the next few months.

"In the current state that we are right now and these babies being as fragile as they are for the next four months, at minimum, this ultimately wasn't that difficult a decision for me," Posey said. "From a baseball standpoint, it was a tough decision. From a family standpoint and feeling like I'm making a decision to protect our children, I think it was relatively easy."
