What's happened to the .300 hitter?

[D. Bergin]

Not only better pitching, more specialized pitching.

Less guys on the juice, is an obvious correlation.

Some ballparks have actually moved their fences out, as opposed to everybody moving their fences in a decade and more ago. Colorado is no longer the hitting wonderland it used to be, because of adjustments they've made in the last decade.

Infields are much improved from a defensive standpoint. Astroturf is a much better quality and more forgiving then it used to be, so you don't get the ball bouncing like a superball across the infield like you used to in Minnesota, St. Louis, Kansas City and other places.

Defensive alignments. Defensive metrics have made huge strides in the last 5 years or so, and regular pull hitters who used to regularly bat .300 or close to it are seeing their batting averages plummet as they are lining into perfectly aligned fielders.
