Its really annoying the media is all looking at Bryce Harper as the bad guy in the incident. I hate when pitchers throw at a batter for "showing them up". Its one thing if the guy did something that could've legitimately injured someone or something (dirty slide, catcher takeout etc) but hitting a dude because your mad he hit a homer is such pussy shit. A batter can't do anything to defend himself and if he does, he'll get suspended more than you will, especially if its a starting pitcher, he'll miss one start max. If you don't want players showing you up, admiring home runs, or whatever, don't give up bombs to them, its that simple.
It's also a joke that pitchers get mad at hitters for admiring home runs, but will stand on the pitchers mound and do dances and shit after saves (K-Rod, Valverde, Rodney, etc).
