Giants CEO Larry Baer and his wife, Pam, welcomed a rollicking Major League Baseball gang of about 2,000 — team owners, managers, investors and executives, as well as sponsors, front office staff members, families, dignitaries and friends of both the Giants and the Kansas City Royals — to Pier 27 for a pre-Series shindig. “It’s nice to be back to crab cakes and wine and our own vegetable garden,” Pam Baer said at the event.
