On Tuesday, the Washington Post reported the Nationals offered outfielder Bryce Harper a contract extension on the final day of the final homestand in the 2018 season. Harper declined and opted for free agency.
Here's how much the Nationals offered, which now establishes a baseline for teams bidding for Harper, per the Washington Post's Chelsea Janes:
Nationals' offer to Bryce Harper was roughly $300 million for 10 years -- so an AAV of $30 million -- according to multiple people familiar with it. No opt outs.
Also keep in mind, this is $100 million (or more) below where Scott Boras will likely set his initial asking price.
