"it's not good for baseball in that situation" -- unwritten rules being broken, playing baseball the wrong way

If an established position player is pitching then swing all you want imo.

This is not a triple A pitcher trying to get a job in the majors and they are adding to his era in a blowout, the other team basically called in the L.

Astros broadcast just said that A's fans stand out to them because they seem to boo only players from the 2017 team, and not ALL of the current Astros like other fans do.

i believe that the best fans in baseball will also boo the proper players

Wonder if Springer will get such a treatment.
