A few things have happened in the past week, from the Royals going on an incredible losing streak to Phillip Humber's perfect game.
So how about those rankings?
1. Texas Rangers (Last week: 2) - The Rangers are on fire right now, winning 9 of their last 10. Their run differential right now leads the league at +52, more than twice as good as the Braves, who are the next best at +25.
2. Los Angeles Dodgers (1) - So far, the Dodgers are undefeated at home and Matt Kemp is on pace to win the Triple Crown pretty handily. Of course its early, but h's biggest competition so far is teammate Andre Ethier, who trails him by only 1 RBI.
3. Washington Nationals (6) - Are the Nationals actually a good team now? It's starting to look like it, which is a good sign for the former Expos. Perhaps the Redskins will take a hint and move back into relevance soon.
4. Detroit Tigers (3) - They're slipping a little bit, going only 5-5 in their past 10 games, but on the plus side, Drew Smyly and Justin Verlander are 1st and 3rd in the AL in ERA, respectively. So that's a start.
5. St. Louis Cardinals (4) - They're the only National League team with multiple 3-game winners, with surprising Kyle Lohse and Lance Lynn getting the Cards 6 wins in only 7 combined starts. Not too shabby.
6. Atlanta Braves (12) - With 8 wins in their last 10 games, the Braves are on quite a hot streak, and as mentioned before, they have the 2nd best run differential in baseball. Tommy Hanson only averages 6 innings per start, but those have been high quality innings.
7. New York Yankees (7) - They're on a 3-game winning streak, thanks to the fact that they got to play the lowly Red Sox this weekend. Nick Swisher is crushing the ball, currently leading the AL in RBI with 20.
8. Chicago White Sox (8) - Phillip Humber's perfect game was a great highlight to their week, and they've also won 3 straight. Things are looking fine for the White Sox at this point in the young season.
9. New York Mets (11) - The Mets are on a bit of a cold streak lately, but let's see if they can turn it around a bit. David Wright is approaching the Mets' team record in RBI. The fact that he's only 29 says a lot about the Mets' history.
10. Blue Jays (13) - With 3 straight wins, they're still playing pretty well. How long can they hang around the top of arguably the toughest division in baseball? They'll need more from Jose Bautista and Brett Lawrie for that to last long.
11. Arizona Diamondbacks (5) - 3-7 in their past 10 games, the Diamondbacks are starting to slip a bit. With the way the Dodgers are playing right now, they can't afford to slip like this for much longer if they want to have a chance.
12. Tampa Bay Rays (10) - They're not as bad as they played against the Red Sox, and their pitching hasn't been as awesome as they're supposed to be. No worries, Rays fans. That will change soon.
13. Baltimore Orioles (14) - The Orioles are still playing pretty well, and closer Jim Johnson is tied for the MLB lead with 7 saves. They struggle against good teams, but then again, who doesn't? That's why good teams are good.
14. Cleveland Indians (21) - If they could play all their games on the road, they might by in the top 5. They're 7-2 on the road, despite winning only 1 out of 5 in Cleveland. Also, Chris Perez is 2nd in the AL with 6 saves.
15. Colorado Rockies (23) - They're 2nd in their division right now, and let's be honest, there's no shame in trailing the Dodgers right now. They have the good fortune of playing the Pirates next, so they should continue to do well.
16. San Francisco Giants (19) - With a .500 winning percentage and a run differential of 0, the Giants are about as average as a team can possibly be right now. One good thing is that Buster Posey looks like he's completely recovered from last year's injury.
17. Philadelphia Phillies (16) - Right now, they're in last place in the NL East. That's going to be the toughest division in baseball, so obviously they need to step it up a lot if they want to head back to the playoffs.
18. Cincinnati Reds (17) - Joey Votto isn't having a terrible year, but the Red will need him to return to MVP form if they're going to do anything this year. Also, they'll need a LOT more out of Mat Latos and the rotation.
19. Seattle Mariners (18) - They've lost 4 in a row, one of which was Humber's perfect game. Needless to say, this is a borderline minor-league offense, and the pitching just can't bail them out every time.
20. Oakland Athletics (24) - The Athletics only have 4 regulars with over a .200 batting average. For those of you keeping score at home, that's pretty awful. Cuban import Yoenis Cespedes is by far their best hitter so far.
21. Miami Marlins (25) - They just swept the Cubs, but... they just swept the Cubs. In case you haven't noticed. that's not the most impressive accomplishment ever. We'll have to see more from this team to see if they can meet their high expectations.
22. Milwaukee Brewers (22) - While a lot of teams are moving up and down the rankings, the Brewers are standing pat, thanks to the fact that, quite frankly, they're just continuing with their previous mediocrity.
23. LA Angels of Anaheim (15) - The Red Sox have gotten a whole lot of attention, but the Angels really aren't doing a whole lot better, and their preseason expectations were just as high, if not higher.
24. Boston Red Sox (9) - Speaking of the Sox, their ONLY bright spot might be David Ortiz, who leads the AL with a .436 average. Other than him, however, the Sox have been downright embarrassing.
25. Houston Astros (20) - The Astros are slowly settling down towards the bottom of the rankings, much like they did last year. 7 losses in their last 10 games brings them down another 5 spots. Let's see if the slide continues.
26. Pittsburgh Pirates (27) - I'm willing to bet that the Pirates will extend their remarkable playoff drought. It doesn't help at all that they're still averaging a measly 2 runs per game. Even the best pitchers would lose games with such little support.
27. Minnesota Twins (29) - Their -27 run differential is the worst in all of baseball. That means that not only are they losing games, they're losing them BADLY. Remember when they used to be competitors in the AL Central?
28. Chicago Cubs (28) - The funniest part about those video game commercials is the idea of the Cubs winning the World Series in 2012. Not only does it seem like they're NEVER going to win, it's even more of a lock that 2012 won't be their year.
29. Kansas City Royals (26) - With a 10-game losing streak, the Royals were in danger of being the last place team, but they get the benefit of the doubt... this time. Let's see if the Padres can keep the 30th spot from wire to wire.
30. San Diego Padres (30) - Baseball's worst team is on a mini 2-game winning streak, but they lost 7 out the 8 before that, and they're still sporting a rather atrocious 5-12 record. Not out of the basement quite yet.
