What happened: New York Mets co-hitting coach Johnny Washington worked closely with South Korean infielder Si-hwan Roh during the 2021 season with the Hanwha Eagles, according to Jon Morosi of MLB Network. Roh, 25, is posted for Major League Baseball clubs this offseason. The Mets previously hired Johnny Washington as co-hitting coach to help guide their offense heading into 2027.

Why it matters: Washington's prior experience with Roh gives New York immediate familiarity as front offices evaluate the posted infielder for the 2027 season. The existing connection could ease a transition to North American baseball if New York pursues him. Any agreement would require navigating the standard posting window and release fee structure.

What to watch: Major League clubs have 30 days to negotiate terms with Roh once his posting is officially finalized.
