The Pirates used their team account ("Pirates") to share a number of photos, videos and stories. Around 10 a.m., the Bucs' Snapchat caught McCutchen, Marte and Polanco in a more relaxed moment, rapping and dancing behind the "Bubblegum Dugout Cam" filter.
Pregame dancing in the dugout is nothing new for McCutchen and the Pirates, of course. This is the group that made popular the dugout dance party, after all.
Taking things in a slightly more disturbing direction, the Pirates ran catcher Francisco Cervelli through the "Zombie" filter.
Snapchat Day didn't end when the game began, either. The Pirates captured Juan Nicasio's first pitch to Rays outfielder Steven Souza Jr. from just behind home plate.
