Here is the whole video. You can see that Anderson is fighting being pushed off the field. And it was the second time Vaughan just picks him up and takes him down the dugout steps. He might have initially been dazed, but he was fighting, both times, from being pushed off the field by his teammates.
In the end, imo, Anderson was the instigator. He'd already received one warning from the umpire about his jawing at a rookie player for the Guardians. And the other night pushed someone off base with a hard tag, and Ramirez said he'd been making really hard tags on people. That's why you see Jose get up and gesture 'Wtf, man?' (At least that's how I interpreted it.) I don't know what fines or suspensions will get handed out, but I hope Anderson gets the most in both. And I'd really like to know what Grifol said to Francona that triggered Francona. But Francona's response 'Boys will be boys' (in his post game presser) just made me want to throw up a little. Ugh. Poor excuse for grown men letting their emotions run away.
