My view: You can "save" par, bogey, double, triple, etc. by 1-putting instead of two-putting. It has nothing to do with how poorly you played the hole up until that point. If you get up and down in your last two shots, starting from off the green, that was a save. If the "up" came from the sand and either it went "down" in the same shot, or the next shot goes down, it's a sand save. I have had thousands of up and downs for bogey, and unfortunately many for double and triple as well. Basically, any time you 1-putt, you "saved" a stroke because 2-strokes on a green is the standard expectation for every green, everywhere, for everyone.
