On Friday, Machado took exception to a tag placed on him by A's third baseman Josh Donaldson.
On Sunday, Machado was nearly hit by a pitch from A's lefty Fernando Abad. On the next pitch, Machado's bat went flying down the third base line. Machado appeared to be motioning that it slipped out of his hands when Oakland catcher Stephen Vogt confronted him.
The benches cleared again after Machado began barking back at Abad, who was also ejected. The typical jogging bullpen pageantry ensued. No punches were thrown, but it doesn't seem likely that either side will forget about these incidents for some time. Luckily, they won't play each other again until July 18, so everyone will have a chance to cool off and realize that punching one another in the head is probably a waste of time.
