The earliest reference to the Astros' version of the "Killer B's," according to the cryptic powers of Google, is dated March 31, 1996. Jeff Bagwell, Craig Biggio and Derek Bell were all holdovers from the '95 squad, and third baseman Sean Berry was acquired from the Expos the following winter. So that made four core players whose surnames started with the letter "B." Little wonder, then, that a collective nickname followed.
