1. Bags. Padded. No need to have fingers and thumbs exposed when runners slide hands first, which they should not.
2. Wear BLACK bags! Geez! I saw Derek Jeter slide hands first into second base today and even on the slow mo HD replay it was difficult to tell whether he was safe, in part, because his gloves were the same color as the bag. How much imagination and brains does it take to figure out that you want to help the umpires who are increasingly exposed as merely guessing on many, if not most, calls.
