To address the original question...Perhaps it's six to one and one half dozen to another, but I think that revitalization might be a better term than saving. Baseball has been extremely ridged when it's come to changing the way that the game has been played. The game itself and a large part of the fan base are deeply steeped in the game's tradition and over time there has been a certain romanticism of the game as being timeless. It's records are more revered than those in any other game and the game's stats are always use as points of reference when comparing not only players, but eras. That said, metrics have become so advanced and have become a HUGE part of not only how the game is played and managed on the field, but also how front offices assess their own players and potential trade/FA targets. Knowledge is power and MLB has embraced this new age way of approaching the game, yet has remained antiquated in many ways and now is trying playing catch up with the rules. IMO the universal DH should have come long ago. It was inevitable and the introduction of inter-league play was the perfect time to do that. Pace of play has been an issue for better than a decade, yet as of now the only on field measure that has been taken to address this is the restriction on mound visits and the three batter rule for relievers. The pitch clock looks to be coming, but it's way overdue. The over sized bases may prevent some injuries and that's a good thing and if they add a small amount of excitement to the game via stolen bases that's also a good thing. I'm a bit mixed on the shift rule change (I won't call it a ban), but I'm all for keeping the infielders in the infield.
I like that baseball has realized the need to do something to make the game more attractive, but I think that the game could have avoided much of the bad rap that it's gotten if much of this had been implemented many years ago as these needs were recognized. I thought the "ghost runner" was a great addition to the game that not only in large part got rid of games lasting more than 12 innings, but gave fans an interest in extra inning games. IMO extra inning games become exciting when players get into scoring position, more so with less than two outs. Starting out extras with a runner on 2B give the fans that level of excitement right from the get go with both teams having the same opportunity with the likelihood that the game will be over in fairly short order. Ironically this seems to be going away after this year, I hope the powers to be reconsider. Anyway, that's my 2 cents.
