Every series tells us more about this team, even the 4 game series the Sox split with the pale Sox.
But since you raised this topic, a couple of points.
The Sox have already taken 2/3 from the Phillies, who have the best won-lost record in MLB, and they did it in Boston, where the Sox still have a losing record.
The two winningest teams in the AL right now are the Orioles, who took 5 of 6 from the Sox, and the Guardians, who took 5 of 7.
As for the Dodgers, while they are definitely a good team, they miss Betts. They are 11-12 since he went on the IL. They just lost 2 of 3 in Detroit and 3 of 3 in Philly and are now 56-41, which would put them 2 games ahead of the Sox.
Right now the NL West, against whom the Dodgers play 52 games this season, are kind of lousy. The AL East still has the best W-L record in MLB. Thus, in part, do the Dodgers have a +88 run differential, twice the Sox +44. The Sox have better pitching and the Dodgers better hitting (but maybe not with Mookie out).
