That may have been true a couple weeks ago, not so much with Yelich, Vaughn, and Chourio back. And I think you need to look at some of the other lineups around the league. No one's running out 8-9 hitters batting a reasonable average.
Yesterday, for example, yes Rengifo, Perkins, and Ortiz have putrid season numbers. Everyone else is .700+ OPS or better.
The Cardinals have 5 players below .700 (although one is just barely).
Surely the vaunted Dodgers lineup must be way better? Nope, they have 3 players below .700 (although to be fair, they're closer to .700 than the Brewers 3).
