From McCalister's blog:
"If Cueto has any problem, he can throw at me and I'll definitely return the favor," he said. "I didn't like that one bit. We don't retaliate. We just take it game by game and try to better ourselves. Hopefully he learns to grow the hell up. ... You're up 4-0. Grow up. I hope he hears this because I really don't care."There is video at the link above.
It looked clear to several observers, including myself, that Cueto's pitch was unintentional. However, home plate umpire Bob Davidson, known to be hot headed at times, warned both teams. The Cubs went on to pitch wildly inside to Ryan Hanigan and actually hit Shin Soo Choo without a peep from Davidson.
Garza said that Cueto's pitch help wake up a "sleeping dog". That dog, the Cubs, would be a poodle named Gracie.
