New turf has been put in at Marshall University’s new Jack Cook Field in Huntington, and the team is expected to start using the baseball facility this week. The field also has new bullpens, a locker room and coach’s office as well as luxury seating as part of a $23 million upgrade at the stadium. The nearby Dot Hicks Softaball field will get a new clubhouse. Marshall will open its new baseball stadium next spring.
