There has been a lot of talk about Bryce Harper turning down a massive extension offer from the Washington Nationals on the last day of the 2018 season, but dollars and cents weren’t the only reason the star outfielder chose not to entertain it.

According to Chelsea Janes of The Washington Post, the offer Harper turned down was for $300 million over 10 years. While the money is obviously astronomical, Jon Heyman of Fancred Sports reports that it was missing something significant that Harper is seeking — a no-trade clause.
