Turns out Joel Zumaya doesn't just throw heat when he's on the mound, but he also brings it on social media.
Zumaya — a beloved player during the Detroit Tigers' 2006 World Series run known for his 104 mph fastballs — didn't hold back on his Instagram and Facebook, lighting into the Tigers front office and specifically, general manager Al Avila.
"Is there any other true Detroit Tiger Fan as disappointed as I am on how this season is going for the team!!!!," Zumaya's post begins. "WELL I JOEL ZUMAYA # 54 FORMER DETROIT TIGER, truly am disgusted, disappointed, just flat out upset on how this organization has let itself fall into a category which I thought this organization would never see again!
