February 19th Baseball Spring Training camps official open for most MLB teams, with full squads reporting the following week between 23rd and 25th. Today team equipment managers are going over their list checking off items and packing up trunks getting ready for some time around February 10th, when those big 18 wheelers will be pulling away from the ballparks on their way to the Florida and Arizona, for that other annual rite of Spring Training “Truck Day”.
