Home of the Lowell Spinners. The Lowell Spinners are a Short-Season A minor league baseball affiliate of the Boston Red Sox.. A beautiful minor league ball park on the banks of the Merrimack River. Yes, there really is a giant milk bottle on the back wall. During half time kids are given the chance to "run the bases" and put on funny sumo wresting costumes. It is truly a family and kid friendly ball park.
