It started with the suggestion by agent Rachel Luba that her newest client, outfielder Yasiel Puig, might want to get into a throwing contest with another of Luba Sports' athletes, Trevor Bauer.
When Jackie Bradley Jr. saw such a thing, he couldn't resist throwing his hat in the ring.
Bauer welcomed the fellow free agent, making reference to perhaps his most famous throw, when he launched a baseball into the Kansas City stands just before Cleveland manager Terry Francona took him out.
Bradley Jr., however, does have his own experience throwing baseballs out of the field of play in impressive fashion.
Anyway ... Challenge accepted. Let's do this Major League Baseball!
