"If you're going to fix the strikeout problem, one that is most prevalent in the late innings, this is where you start. The people who obsess over the pace of the game often make suggestions that target specialization and batter-by-batter baseball -- usually mandating that a pitcher must face multiple batters before he can be removed. That's a half-measure. The simplest, most elegant and most effective way to start fixing the strikeout problem is with one rule change:
"No pitcher can be removed once an inning has begun, absent evidence of an injury or at least six batters faced in the inning. A pitcher removed due to injury must immediately be placed on the 15-day disabled list."
