From ESPN magazine (Jan 26) issue:
K Korner says: The Reds think Ramon Hernandez, whom they acquired from the Orioles in December, is their solution at catcher. Dusty Baker values defense behind the plate, which is why he often played Paul Bako there last season. But Baker will find out that the 32 year old Hernandez has slipped in that regard. “He gets lazy,” says a scout. “He backhands balls in the dirt instead of moving his feet.”
I have no idea if this is true or not and know nothing about Tim Kurkjian, who writes this column (ESPN mag started showing up in my mailbox unsolicited recently); but it would explain his high PB count last year.
