MLB Network Reporter Harold Reynolds mentioned that the Phillies are working with Scott Boras on deferring money for Bryce Harper with Opt Out years much like the deal Boras worked out for Matt Scherzer and The Nats.
Nats offered Harper 100M of Deferred Money in the 300M offer for 10 years. The Phillies would defer much much less and will eclipse Stanton contract maximum of 325M.
