Ever since he was a kid, Isiah Kiner-Falefa has heard all about the cousin who was a Hall of Fame slugger for the Pittsburgh Pirates years ago. Now he finally knows kin from Ralph Kiner’s side of the family. In a touching rendezvous Monday at Citi Field, the 30-year-old shortstop greeted Scott Kiner — son of the former Pittsburgh outfielder — before Kiner-Falefa and the Pirates played the New York Mets. Second cousins once removed, the two exchanged hugs and gifts in the Shannon Forde Press Conference Room. An emotional Kiner-Falefa, who grew up in Hawaii, said it was the first time he’d ever met anyone from Ralph Kiner’s part of the clan and something he’d always dreamed about.
