Two of the biggest surprises in baseball so far this season have probably been the surprisingly good play of the New York Yankees and the mediocre performance of the defending World Series champion Chicago Cubs.

However, no team has been more impressive through the first three months than the MLB-leading Houston Astros, who are +500 favorites to bring home their first World Series title.

The Astros are running away from their competition in the American League West, and it would be shocking if any of the other teams overtook them for the division lead in the second half. But the Yankees and Cubs both find themselves in extremely close races and could be battling to get into the postseason all the way into late September.
