The balls are juiced, guys (in that it's smoother). Stop questioning whether it is or not. It's been confirmed by other teams in the postseason, by both the dodgers & Astros and more importantly the pitchers themselves. Only people who are denying are MLB officials themselves, diverting the blame to pregame rubbing mud being the differentiator.
Just to show how juiced MLB balls in general are juiced, I have a somewhat fun story....
Couple years back, my son was trying out for a traveling baseball team. The team was organized by an MLB employee so for the tryouts, they had actual MLB baseballs (he just took some boxes from his office).
Well, sufficed to say, the kids were MASHING the baseball. My son, who really has never been a power hitter due to his stature, but can always square up a ball consistently, but 6 of 8 swings over the fence. Another kid we know who is a power hitter, consistently put his HRs during tryouts into the freeway (50ft+ beyond the HR fence). It was like they were hitting tennis balls.
Additional fun fact - first practice the coach showed up with more MLB balls. Though he "accidentally" grabbed a few boxes of balls that were autographed by a recently traded closer
