It's Keith

[Edgy MD]

Newsday digs for the story of how LuDu (new terrible nickname coined just now) became adept at hitting lefties, and ties it to a pre-spring session he had with Keith Hernandez.

Interesting is that the Mets arranged it after scheduling a sit-down with Sandy and Keith to discuss the organizational hitting philosophy. Unclear is whether they wanted to sell the philosophy to Keith the critical broadcaster or to Keith the occasional instructor, so Duda wouldn't be getting mixed messages.

I don't care if Keith learned it from stone tablets, whatever he taught Duda has been working (knocking wood). And if it differs from the organization's philosophy, I'd rather he uses the tips that work.

OE, IIRC Ralph Kiner said that in all his years of association with the team, not one player ever asked him for a hitting tip.

If LuDu sticks I will file a complaint with the nickname association. They have yet to even consider "The Lumberjack".

If it sticks, I'm gonna beat myself up.

That sounds reasonable.
