Here are this week's rankings:
1. Cleveland Indians (98-58 overall record, No. 1 ranking last week) -- Last year's World Series runners-up have peaked at the precise moment they needed to assert themselves. This year, their rotation has the talent and depth to seal the deal.
2. Houston Astros (95-60, No. 3) -- They've been reinvigorated since picking up right-hander Justin Verlander.
3. Los Angeles Dodgers (99-57, No. 2) -- After losing 15 of 16, the Dodgers have gone 7-6. So much of their historical winning run was accomplished without left-hander Clayton Kershaw. If they are to make a serious playoff run, it can't be all on his shoulders. Is fellow starter Yu Darvish up to the task?
4. Boston Red Sox (91-64, No. 5) -- They could still be dangerous in the playoffs if starters Chris Sale and Drew Pomeranz are at the top of their games and either 2016 Cy Young Award winner Rick Porcello or Eduardo Rodriguez can step up. Doug Fister? Please. David Price is now a serious weapon out of the bullpen.
5. Chicago Cubs (87-68, No. 4) -- A 10-2 run during the past two weeks has all but clinched the National League Central crown and may help in the confidence category. What would help more is the starting pitching stepping up. If they can't, the Cubs will be a quick out.
6. Washington Nationals (94-61, No. 6) -- It may be all about how strong right fielder Bryce Harper can come back from his serious leg and knee injuries. With him healthy and at top of his game, the Nationals can be as tough an out as there is in this year's postseason. Without him, their lineup is still good, but not nearly as tough to navigate.
7. New York Yankees (86-69, No. 8) -- Manager Joe Girardi has a secret weapon: an exceedingly deep bullpen. With a rotation that features Luis Severino, Sonny Gray and CC Sabathia as its top three, it might make sense to add Masahiro Tanaka as a reliever who can come in for two-three innings at a time rather than forcing him into the rotation.
8. Arizona Diamondbacks (90-66, No. 7) -- The Diamondbacks have been greatly rewarded for their pro-active trade that brought them in right fielder J.D. Martinez. For the season, he has 43 home runs and 97 RBIs, but he has hit 27 homers in just 214 at-bats since the trade to Arizona. That figures out to a home run every 7.9 at bats. Trust me, the Dodgers don't want to face this team in the playoffs.
9. Minnesota Twins (82-74, No. 9) -- They've been a great story, but without third baseman Miguel Sano, they will be one and done in the wild-card game.
10. Colorado Rockies (84-72, No. 11) -- This write-up on Colorado can also serve as the write-up for Nos. 11 and 12, who, like the Rockies, are chasing the second wild-card spot. None of these teams will beat Arizona and right-hander Zack Greinke in the wild-card game.
11. St. Louis Cardinals (81-74, No. 13)
12. Milwaukee Brewers (82-74, No. 12)
13. Los Angeles Angels of Anaheim (77-78, No. 10)
14. Texas Rangers (76-79, No. 15)
15. Kansas City Royals (76-79, No. 16)
16. Seattle Mariners (75-81, No. 14)
17. Tampa Bay Rays (76-80, No. 18)
18. Baltimore Orioles (75-82, No. 17)
19. Toronto Blue Jays (73-83, No. 19)
20. Miami Marlins (73-82, No. 20)
21. Pittsburgh Pirates (71-85, No. 21)
22. Oakland Athletics (72-83, No. 26)
23. San Diego Padres (70-86, No. 22)
24. Atlanta Braves (70-84, No. 25)
25. New York Mets (66-89, No. 24)
26. Cincinnati Reds (66-90, No. 23)
27. San Francisco Giants (61-95, No. 27)
28. Philadelphia Phillies (62-94, No. 28)
29. Chicago White Sox (63-92, No. 30)
30. Detroit Tigers (62-94, No. 29)
