Cam York, a mobile defenseman who is expected to be a big part of the Flyers in the near future, signed a three-year entry-level deal with the club Wednesday.

The deal starts this season, general manager Chuck Fletcher said. York will join the AHL’s Phantoms, according to coach Alain Vigneault. It is not out of the question that the 5-foot-11, 185-pound York will play with the defensive-challenged Flyers before the season ends.

A southern California native, York, 20, was selected in the first round (14th overall) in the 2019 draft. He had an outstanding two-year career at the University of Michigan, where he had 20 points (four goals, 20 assists) in 24 games this season.

When the Flyers selected him, assistant general manager Brent Flahr called him “an offensive guy, a terrific skater with a great pedigree” because of his time with the U.S. national team’s development program.

In January, York helped Team USA shock heavily favored Canada, 2-0, to win the IIHF World Junior title. York was the team’s captain. In seven tournament games, he had six points and a plus-4 rating.
