What happened: MLB Network's #MLBCentral spotlighted Brewers rookie Cooper Pratt, who took the field by himself during his MLB debut this past week. The lighthearted moment plays on the longstanding rookie tradition in which veterans hang back so the newcomer gets a solo lap onto the field.

Why it matters: It's a milestone moment for one of Milwaukee's most-watched young players, the same Cooper Pratt the Brewers called up as a top prospect. Clubhouse rituals like this are part of how a rookie gets welcomed into the room, and they tend to follow a player long after the debut box score fades.

What to watch: Watch how Pratt settles into a role with Milwaukee as the club works to steady a 45-28 start.
