Gonna take the rest of the weekend off as I'm just not seeing this sport well currently, but I do want to play this. And I think this is why AI will never accurately replace humans. Yeah, there are some statistical edges for Houston. But the Dodgers just got PUNKED in their own park on Friday. Embarrassed. A computer doesn't take into account pride or intangibles. In a 162-game season, you need to find spots where teams will care. I assure you this will be one for the Dodgers.
