1. Chicago Cubs (27-9, previously No. 1) – The Cubs haven’t let up yet as they have won seven of 10 games to lead all of baseball by a considerable margin. They have posted a plus-109 differential, by far the best in baseball. Chicago has recieved tremendous starting pitching so far with Jake Arrieta and Jason Hammel being in the top three in the NL in ERA.
2. Boston Red Sox (24-14, previously No. 6) – It was a huge week for the Red Sox’ offense as they have won seven of their last 10 games. In three games against the A’s last week, the Red Sox scored 41 runs. They still are looking for consistent starting pitching as the offense can’t sustain this level all year.
3. Chicago White Sox (24-14, previously No. 2) – The White Sox have lost two straight games and are just 5-5 in their last 10 games. Despite this, they still lead the AL Central by five games and have a plus-38 run differential. Chris Sale continues to dominate as the lefty has an ERA of 1.67, third in the AL.
4. Washington Nationals (23-15, previously No. 4) – Washington had a bit of a tough week, losing six of its last 10 games, but fortunately the rest of the NL East struggled as well and the team is still in first place. At the plate, Daniel Murphy is hitting .400, which is the best average in baseball.

5. Baltimore Orioles (23-13, previously No. 5) – With a plus-37 run differential, the Orioles are leading the AL East by a few percentage points over the Red Sox. Baltimore has been led by its offense this season, especially with home runs. Manny Machado and Mark Trumbo have each hit 11, which are tied for the third-most in the AL.
6. Texas Rangers (22-16, previously No. 8) – It may be a bit of a surprise, but the Rangers have sustained their solid play to lead the AL West. They have won seven of 10 games and are one of the hottest teams in the game as it stands now. To this point in the year, they don’t have any superstars, but are playing solid team baseball.
7. Philadelphia Phillies (22-16, previously No. 9) – It’s been a strange start for the Phillies. They are six games above .500, but have a minus-30 run differential. This is an indication that their winning isn’t sustainable, but for now they are winning games and is all that matters. After not knowing who would close games to open the year, Jeanmar Gomez has 14 saves, which leads all of baseball.
8. San Francisco Giants (22-18, previously No. 11) – The Giants are among the hottest teams in the game, winners of seven of 10 to jump to the top of the NL West standings. Their offseason acquisitions are paying off as Johnny Cueto and Jeff Samardzija each have five wins so far this season.
9. Seattle Mariners (21-16, previously No. 7) – Seattle has lost three straight games to fall out of first in the AL West. The Mariners have been led by their pitching as they have allowed less than four runs a game to this point in the season. Robinson Cano remains one of the best hitters in the game as he’s hit 12 home runs and has 34 RBIs to lead baseball in both categories.
10. New York Mets (21-16, previously No. 3) – The Mets have struggled on their West Coast trip as they have lost four straight games and six of their last 10 to fall to third-place in the NL East. Yoenis Cespedes is still swinging a hot bat as he’s hit 12 home runs and driven in 32 runs, which are second and third in the NL respectively.
11. Miami Marlins (20-17, previously No. 12) -- Miami is one of the better teams in the league this season, but unfortunately for them they are in the NL East, one of the best divisions in all of baseball. Giancarlo Stanton is starting to hit as his 11 home runs are tied for third in the National League.
12. Los Angeles Dodgers (20-18, previously No. 13) – The Dodgers are second in the NL West, but there are a few signs that better things are ahead. They have a 9-11 record at home, which is sure to improve and also they have a plus-20 run differential. That is the best in the division and a sign they are the best overall team.
13. St. Louis Cardinals (20-18, previously No. 14) – St. Louis is another team that may be better than its record indicates. They are just 9-10 at home, but have a run differential of plus-49, the second-best in the entire NL. Aledmys Diaz still is among the league leaders in hitting, batting .376, which is second in the National League.
14. Pittsburgh Pirates (19-17, previously No. 10) – The Pirates may need to already have their eyes on the Wild Card as the Cubs could have the division locked up by the Fourth of July with the way they are playing. Pittsburgh is led by Starling Marte, who has a 1.8 WAR, sixth in the NL.
15. Toronto Blue Jays (19-20, previously No. 15) – Toronto has lost two straight games and is in third place in the AL East. The biggest story with the Blue Jays right now is Jose Bautista being punched in the face by Rougned Odor of the Rangers after a late slide into second base on Sunday.
16. Colorado Rockies (19-18, previously No. 19) – The Rockies have won four straight games to get closer and closer to the top of the NL West standings. So far they have been led by Nolan Arenado and his 2.2 WAR, which is the best in the National League.
17. Kansas City Royals (18-19, previously No. 18) – It’s been a tough start to the season for the Royals, especially after the year they had last year. They have a minus-18 run differential which isn’t normal for Kansas City teams. First baseman Eric Hosmer is batting .336, which is good for fifth in the AL.
18. Cleveland Indians (17-17, previously No. 16) – Cleveland has dropped two straight games and currently sit in second place in the AL Central. One thing in its favor is it hasn’t played as many games as everyone else because of a lot of early-season rainouts. This could benefit them down the road.
19. San Diego Padres (17-22, previously No. 26) – It’s been a bit of a struggle for the Padres this season, but if starters James Shields and Andrew Cashner can turn things around from the mound, the Padres could possibly be a playoff contender come the middle of the summer if they don't make any trades.
20. Arizona Diamondbacks (17-23, previously No. 20) – A horrid 5-16 start at home has been the Diamondbacks’ biggest downfall this season. They have a few solid young starters, but Arizona doesn’t appear to be a team that will be making noise this season.
21. Tampa Bay Rays (16-19, previously No. 17)
22. New York Yankees (16-20, previously No. 28)
23. Los Angeles Angels (16-21, previously No. 24)
24. Detroit Tigers (16-21, previously No. 21)
25. Oakland Athletics (16-22, previously No. 22)
26. Milwaukee Brewers (16-22, previously No. 23)
27. Cincinnati Reds (15-22, previously No. 25)
28. Houston Astros (15-24, previously No. 27)
29. Minnesota Twins (10-26, previously No. 29)
30. Atlanta Braves (9-27, previously No. 30)
