Mmm - dunno. Verlander is old and Urias is injured. Overall the league ERA has not skyrocketed, and much of the increase can be attributed to the unnecessary changes to baserunning.
The pitch clock was needed IMO because the prima donnas were making the game unwatchable. The games had lengthened from 2.5 hours in the 1970s to 3 hours and 10 minutes last year.
