J.T. Realmuto broke the thumb on his throwing hand while blocking a pitch six days ago.
He practiced with the Philadelphia Phillies on Wednesday, but an MRI later revealed the small fracture. Realmuto said he's confident he'll be ready for the season opener on April 1 but wants to make sure his thumb has healed.
"I'm not very worried about my thumb, so if I was a Phillies fan, I wouldn't be too worried," he said.
The Phillies signed the catcher to a five-year, $115.5 million contract this offseason.
