ST. LOUIS (AP) _ Rawlings Sporting Goods Inc. is recalling about 45,000 aluminum softball bats because of safety concerns, company officials said Thursday.

The U.S. Consumer Product Safety Commission and Rawlings have received 16 reports of the top of the bats shearing off. No injuries have been reported.

The recall is limited to aluminum slow-pitch softball bats. The bats include an end weight that is screwed in, which officials believe is creating the stress that causes the bat to break.

The recalled bats are model numbers SBZ2, SBZ3, SBZ4, SBB3, SBB4, SBB5, SBB6, SBB7, SPT-PK2, and DUAL-E. ``Rawlings'' and the model numbers can be found on the barrel of each bat. The bats are adult-sized, and come in various colors.

Major retailers, including Wal-Mart, Target and Kmart, and sporting goods stores nationwide sold the bats from September 1997 through May 1999 for between $40 and $200.

Consumers may call Rawlings at 800-367-3455, or write the company at P.O. Box 22000, St. Louis, Mo., 63126.
