The annual "Truck Day" celebration has been a tradition for the Red Sox since 2003. Red Sox pitchers and catchers will report for duty on Tuesday, Feb. 11 and hold their first workout the next day on Wednesday, Feb. 12. Alex Cora's team will hold its first full-squad workout on Monday, Feb. 17.

The celebration of Truck Day has been a Red Sox tradition since 2003, signaling the unofficial start of Spring Training.

Truck Day is one of those “only in Boston” photo ops, much like Allston Christmas, the L Street Brownies swimming in the ocean on New Year’s, and U-Hauls getting “Storrowed.”
