Harper declined the Nationals' one-year, $17.9 million qualifying offer and became a free agent Monday, Mark Zuckerman of MASN Sports reports.
Nobody expected Harper to accept this offer, as the 26-year-old superstar is looking to sign what is likely to be the largest free-agent contract of the offseason. While he got off to a slow start in 2018, Harper still finished the season with an .889 OPS, 34 homers and 100 RBI while leading the majors with 130 walks.
