The Hardball Times' Clay Davenport has his first run of projections for the 2014 season. For the Astros' purposes, let's take a look at Davenport's AL West:
Oakland: 88-74
Texas: 87-75
Anaheim: 84-78
Seattle: 83-79
Houston: 70-92
Now, looking at his Postseason Odds, we see that the Astros averaged a 67-95 record with a 1.98% chance of making the postseason (with the 2014 season simulated one million times), which is actually higher than the Cubs' chances of making the postseason.
