From the article:
Meanwhile, evidence that the shift is harming careers and the entertainment value of the game continues to mount. Entering this week, the major league batting average was .233, the third-lowest April batting average in the 102 years of the live ball era (1943, 1968). Batting average on balls in play is down to .286, the lowest in 29 years. Hits are at an all-time low. Strikeouts are at an all-time high.
Strikeouts aren't at an all time high because of the shift. We're here because of the launch angle.
Honestly, I don't think the shift affects pace of play. If you want to beat the shift, learn to hit the other way.
The shift has been around since Ted Williams.
