They are making some attempts to engage fans through social media, and have produced some shows that have "hip" celebrities (does Fat Joe count?) saying YOLO and swag which somehow relates to baseball. The WBC, Japan, and Australia trips are clearly a secondary priority. FIFA shuts down domestic leagues to stage friendlies, qualifiers, and tournaments. MLB puts pitch limits on pitchers, and the best don't even play during the WBC. The Japan and Australia trips is just one series a year.
MLB's biggest problem with young people is that most of them are priced out of stadium, and now they are starting to get priced out of watching on TV. MLB has to know this, and almost certainly could care less.
