First of all, any excuse to post IMO James Brown's greatest jam: Sept. 2014: Mike Fiers (then on MIL) hits Giancarlo Stanton (then on MIA) in the face with a 88 MPH fastball, fracturing his jaw, ending his season and causing him to wear a batting helmet to better protect his jaw to this day. June 2018: Mike Fiers (then on DET) hits Giancarlo Stanton (now on NY) in the front arm with a 88 MPH fastball. Stanton was less than pleased, as you can imagine, and words were exchanged. In his next AB, Stanton hit a 456 foot HR off Fiers and pointed back to Fiers after he crossed home. Aug 2018: Fiers is traded to the A's and 'likes' a series of Tweets including one saying 'Hit Stanton in the mouth for me'. Twitter controversy ensues. Sept 2018: Fiers and Stanton meet again. All of this is in this clip if you are interested, the HR is at 2:39 and is impressive.
