They absolutely are.
They are tied with the Tigers and the Brewers with most wins, 64, but their run differential is just +23.
Plus the AL East Division remains the toughest of the six.
And the Sox are just 5 games back of the Jays despite playing a tougher schedule.
I think this is the best Sox team in years. The offense is ranked 4th in runs scored and 5th in team OPS. The pitching is ranked 10th in team ERA and 4th in quality starts. And I'm saying now that the dipsticks focused on total errors have failed to see that the Sox defense is actually pretty good, especially at catcher, CF, RF, LF, 3b, SS, and even 2b. The talksox fixation on total errors is foolish. Even the baserunning is pretty decent.
Another starter would be great, but they are mighty expensive--like the Padres expecting Duran for Cease. What a joke. Same goes for good bullpen arms--go after them but don't give away the farm. I see no compelling need for a first baseman or, for that matter, a catcher.
