A Montana jury will decide whether a baseball bat manufacturer can be held liable for the death of an 18-year-old pitcher who was hit in the head by a hard line drive.

Hillerich & Bradsby, manufacturers of Louisville Slugger bats, is being sued by the mother of Brandon Patch, who died in 2003 after a batter using an aluminum bat smacked a ball so hard that Patch had little time to react.

Patch's family contends the aluminum bat is unreasonably dangerous. Attorneys for Hillerich & Bradsby contend aluminum bats are no more dangerous than wooden bats.

The jury trial is expected to go through at least early next week.
