"Pitchers are dominating the strike zone like they never have before. After the 1968 season, in which MLB pitchers ran a 2.41 strikeout-to-walk ratio and a 16% strikeout rate (on the heels of similar numbers in 1967), the game's powers that be made radical changes to the rules to restore order. Well, MLB pitchers have set records for K/UIBB in every one of the past three seasons, pushing the mark to 2.7 in 2013, with a 20% strikeout rate. Pitchers are dominating hitters today in the same way they were in 1968, with the difference being masked by the power modern hitters generate when they do make contact. Baseball today is basically baseball in 1968 plus weight training and equipment changes."
