As first reported by MLB.com’s Steve Gilbert, Diamondbacks catcher Henry Blanco was diagnosed Tuesday with a torn ulnar collateral ligament in his left thumb and is scheduled to undergo surgery Wednesday to have it corrected.
He’s almost certainly done for the rest of the year.
Blanco was injured this past Sunday at Citizens Bank Park when Phillies outfielder John Mayberry slid hard into his mitt on a play at home plate. An MRI taken Monday — with results made available Tuesday — revealed the torn thumb ligament.
The 40-year-old catcher was hitting .188 with a .505 OPS in 21 games as Miguel Montero’s primary backup.
