Mike,

I agree 100%. You are correct about your bat, it must be a 1989 because of his number change. However, I have had 2 1986-89 labeling period bats used in 1990 (with COAs from the Astros team store and corresponding dated tape), but it is most likely 1989.

Mike Specht, I hope you don't mind, but here is the info I asked about about a year ago and you replied to:

Craig Biggio 1986-89 labeling period:
H176: 34 / 31 (21 bats) and 34 / 32 (18)
D143: 34 / 32 (12)
B348: 34 / 32 (75)
M216: 34 / 32 (15)

Biggio 1990 labeling period:
B348 34 / 32 (60)
H176: 34 / 32 (12)

Biggio 1991-97 labeling period;
H176: 34 / 32 (507) and 34 / 32,5 (141) and 34 / 33 (46)
D143: 34 / 32 (6)

Any interest in selling your 1989 bat Mike???

Thanks,
