Last week's ranking in parentheses.
1. Tigers (1): Victor Martinez has been a beast in the second half, hitting .371 with a .945 OPS. The Rays' Wil Myers (.385) is the only AL hitter with a higher average.
2. Dodgers (2): No wonder Don Mattingly left Arizona thinking his team could win 100 games. The Dodgers were 30-42 on June 21 and now are on pace to finish 93-69. They'll be a lot better than that if they keep winning like they have since the slow start, going 37-8 in a historically great stretch.
3. Braves (7): On pace for their seventh 100-win season since 1993. That's two more than the Yankees in that span.
4. Pirates (4): Francisco Liriano's Friday night meltdown in Colorado is reason for concern. He can fall apart once he gets out of sync.
5. Red Sox (3): It has been a grind for more than a month now.
6. Rangers (13): Made up a six-game deficit in the AL West in 12 days. Very good trip to Oakland, Anaheim and Houston.
7. Reds (11): Chicago's Tony Cingrani remains a strong replacement for Johnny Cueto.
8. Orioles (10): Chris Davis is hitting a homer every 16 at-bats since the All-Star break. He projected to 58 through Sunday.
9. Rays (5): Alex Cobb rejoins the rotation Thursday. It needs a lift with Jeremy Hellickson and Roberto Hernandez struggling and Matt Moore sidelined. Moore threw 50 pitches in the bullpen Sunday and hopes to return against the A's this weekend.
10. Royals (12): Impressive in winning three of four against the Red Sox, with the back of the bullpen always a strength. Luke Hochevar has been a difference-maker as a setup man.
11. Cardinals (6): They hope to get Yadier Molina back Thursday, the first day he's eligible to come off the disabled list. He's a warrior who plays in pain, but any catcher with an injured knee is a major concern.
12. Athletics (8): Welcome back, Josh Reddick. His five-homer stretch Friday and Saturday has raised his second-half OPS to .810. The A's need him to keep producing.
13. Diamondbacks (15): Under .500 since the All-Star break, watching the Dodgers disappear into the sunset in front of them.
14. Indians (9): Feeling like they got sucker-punched by the Tigers last week.
15. Yankees (14): Watching Phil Hughes destroy his free-agent value is the latest item on a distasteful menu for the Pinstripes.
16. Blue Jays (19): Some guys regularly contribute beyond their stats. Mark Buehrle is one of those guys, as the Jays' 15-9 record in his starts (and 39-54 record behind everyone else) shows.
17. Mets (18): Third baseman Wilmer Flores has the bat speed and hand-eye coordination to be a tough out, as he showed in his first week in the big leagues.
18. Nationals (17): Jayson Werth has been the most productive hitter in the majors since the All-Star break.
19. Angels (16): Mike Trout has been the AL's Werth in the second half.
