In the AL, they actually do match up OK. Aside from the Astros, no one has a great top 2. Even the Yankees highly paid 1-2 punch of Cole and Rodon hasn't been that great this year. But, they have by far the advantage once you get into a 3rd or 4th starter. The potential playoff Mariners have a very good rotation as we all know, and they're breathing down the Twins necks, but again the Twins hold the tiebreaker on them.
Now the NL, that's a different beast. The NL is so much better than the AL this year.
