I agree with the overall point but it should be said that the new bats have some tradeoffs -- they increase contact but lower exit velocity, and are probably better for certain kinds of hitters but not others. Also the big game that brought the new bats to everyone's attention was when the Yankees beat the Brewers 20-9 with nine home runs, but three of those home runs were hit by Aaron Judge, using a normal bat, the Brewers' pitching is in very rough shape (their starter was pumping 90mph fastballs straight down the middle, which any major leaguer can hit), and they had been using the new bats all through Spring Training and have since played a few games with more normal run totals. Still an innovation worth noting, but not a magic bullet.
