Due to an unexpected illness to MASN's lead Nationals analyst, Rob Dibble, and the planned absence of Ray Knight, MASN will utilize a mix of contributors in the booth for tonight's telecast. Bob Carpenter will call the first, eight and ninth innings, in a one-man booth. He will be joined by: MASN contributor Phil Wood for the second and third innings; Nationals GM Mike Rizzo for the fourth and fifth innings; Nats Xtra host Johnny Holliday for the sixth and seventh innings.
