Manny Machado was constantly booed by Brewers fans during both Game 6 and 7 for his dirty play on first baseman Jesus Aguilar. During Game 7 he laid down a bunt for a single on a 3-2 count.
After hustling down the line, Machado turned towards the crowd and grabbed his crotch. A little response to Brewers fans and their boos.
The MLB has historically not been a fan of crotch grabs aimed at fans. Machado can expect to hear from the league about this. He can also expect another fine coming his way.
