Den,
How is it going? What is the 3 Digit batch code on the bat. The higher the number, the more likely it was used in Spring 1998 or early 1998 by Bonilla.
Rawlings bats are made all year long, so a bat made in November and December 1997 would have "97" stamped in the knob and be used in Spring Training 1998 at the earliest!
Hope this info helps!
