WOW! Yes, Tanner could serve like lightning and it would be slooooow today! Good thought. Wonderful idea about the 4x4 until force fields are invented. With the hot bats, big barrels, etc., today it a huge concern. Want to help me market an idea? Do you remember Sam McDowell? He was known as "Sudden Sam." A big lefty for Cleveland. I remember going to Pilots games with my Dad at old Sicks Stadium in 1969 and getting tickets first row right by the visiting on-deck circle from a business. That was such a small stadium that we were maybe 10 feet from the player. McDowell was on-deck without his batting helmet (remember the pre-DH days). I asked him as a young fan...he took his hat off and the one that he wore in the field had some kind of plastic liner almost serving as a mini helmet that he wore on the mound. I had tried to look it up a few years ago on the net to make sure I wasn't dreaming but found nothing. I have always wondered why that didn't stick more with pitchers at all levels. And I still think could be marketed.
