The MLB Power Rankings heading into Week 4 are starting to show baseball fans early signs of how the summer may shape up. With the month of May on the horizon, the Boston Red Sox and Houston Astros look like they are on a collision course to square off in the ALCS this October.

That being said, there are still a lot of games to go before that can become a reality, and I’m sure the New York Yankees, Cleveland Indians, LA Angels and Toronto Blue Jays - along with a handful of other teams will have something to say about that.

Red Sox cruising through April

The Boston Red Sox have that early World Series look to them. At 17-3, the Sox are off to one of the best starts in MLB history, but don’t let that fool you into thinking this means that Boston will easily cruise into the postseason.

18-2 is the best start for any team through the first 20 games of the season, and it has been done five times in baseball history. According to an report, the 1911 Tigers, 1918 Giants, 1955 Dodgers, 1984 Tigers and 1987 Brewers all started the season at a blazing 18-2 clip.

However, outside of the 1955 Dodgers and 1984 Tigers, who both went on to win the World Series in those years, the other three teams failed to even make the postseason.

That stat isn’t going to bring down Red Sox Nation right now! The Sox have scored the most runs (123) and are second in runs against at 56. These guys are clearly clicking on all cylinders at the moment - which is why they are clear-cut choice for the No. 1 spot in this week’s rankings.

Below is a look at the Week 4 MLB Power Rankings.

Week 4 Top 10

1. Boston Red Sox -- Can they start 35-5 like the 1984 Tigers?

2. Houston Astros -- Looking strong again.

3. Arizona Diamondbacks -- D’backs proving they belong in the West.

4. LA Angels -- They like the road better than home early on in this season.

5. Milwaukee Brewers -- A perfect example of what a week can do!

Winners of 6-straight, the Brew Crew are rising fast.

6. NY Mets -- Cooling off after a hot start but still playing .700 ball.

7. Philadelphia Phillies -- My NL dark horse is cranking it up! Winners of 4-straight and 8-2 in their last 10.

8. St. Louis Cardinals -- Another NL team on a roll. 8-2 in their last 10 and starting to heat up at the plate.

9. Atlanta Braves -- They deserve a top 10 billing. This team is rounding into shape and will be fun to watch this season.

10. Toronto Blue Jays -- The Jays are playing well so far in 2018.

Best of the rest

If the Boston Red Sox are the hottest team, the Cincinnati Reds are their polar opposite. At 3-18, which includes a 1-9 run in their last 10, the Reds are truly sputtering at the moment.
