Doubles and triples are dwindling in MLB. Blame better outfielders and sluggers.

1. It's a combination of all those things

As a die hard Dodger fan it is very annoying to me that the analytics nerds "recommended" the hitters simply swing for the fences. That's why the Dodgers hit a lot of solo homeruns because there's no one on base. It has been maddening at times (for Dodger fans) when a simple grounder would score a run but no, let's try to hit it out of the park = strikeout.

This power over contact approach has resulted in batting averages going down seems like every year. Trea Turner won the NL batting title last year hitting just .304.
