Col Dave GRrob just posted this glove news on the MEARS web site.
"Minor league Cobb talking with veteran Sam Crawford. Cobb wanted to hear more. “Hell I can’t gab all day” said Wahoo. “Break in a backup glove or two in case your number one leather is ripped.” Cobb didn’t want to admit that he could barely afford one old glove. Cobb was encouraged to show Wahoo his own particular glove. “As an experiment, he had cut the leather out of the palm of his glove to expose the raw flesh, so that any catch was essentially a bare-hander. Crawford grinned, saying, “I did that as a kid-to keep the balls from sliding off the leather. No more though.”
It's interesting how many players did cut a hole in their glove (Ruth, Wagner etc.) and for basically same or similar reasons.
That excerpt was taken from an article glover Grob was reading. It mentioned later on that Cobb took his gamer Spalding glove with him north from Spring Training.
