Third-party logistics service provider Saddle Creek Corp. said today it has acquired ProLog Logistics Inc., a San Diego-based warehousing and fulfillment company. Terms of the transaction were not disclosed.

Founded in 1996, Prolog provides order fulfillment, warehousing, e-commerce, call center, and customer care services from locations in San Diego and Lexington, Ky. All ProLog employees will be retained, and the business will continue to operate as ProLog Logistics, a wholly owned subsidiary of Saddle Creek.

In a statement, David Lyons, Saddle Creek's founder and chairman, said the ProLog acquisition will "allow us to deepen our fulfillment capabilities, providing a broader range of services and greater value to our customers."

This is Saddle Creek's second acquisition in just over a year. In November 2009, it acquired ServiceCraft Logistics, a third-party logistics company based in Buena Park, Calif.

Saddle Creek is headquartered in Lakeland, Fla.
