Sometimes, we forget that while we're looking up platoon splits on Fangraphs, the batting coaches and analytics guys are looking at completely different stuff these days (same goes for most of the bullpen choices).
Never mind that Gosselin gets most of his playing time against lefties, or that lefty-hitting Adam Haseley could’ve stood in for Harper. Girardi felt that Gosselin was the choice against Mets righty Rick Porcello.
“We just liked the matchup,” Girardi said. “I talk to my coaches a lot, especially [hitting coach] Joe [Dillon], about bat paths and who they match up well against. We just liked it.”
