At the buzzer on deadline day, the Giants agreed to send fan-favorite Mike Yastrzemski to the Royals for Yunior Marte.

When the Royals traded for four players in three deals ahead of Thursday’s Trade Deadline, there was a small but very important part of the conversation as team officials welcomed each one to the organization and figured out the next steps.

Yastrzemski hit a 370-foot blast over the wall in right-center field while facing Kevin Gausman in the second inning of the Royals’ game against the Blue Jays.
