Stanton also said that the Astros should be stripped of their 2017 World Series title:
There Stanton is referring to the rules about being popped for PEDs, which prevents you from appearing in the postseason even if your suspension is up by the time it begins.
For the record, Stanton hit 59 homers in 2017. He's something of a guess hitter - he waits for his pitch more than he adjusts on the fly - so, yeah, I could see sign stealing helping him out quite a bit. That would've been scary.
Well, it would've been scary when he was healthy. He was limited to 18 games last year, but he says he's healthy now.
