The Chicago Cubs have reportedly landed one of the biggest free agent prizes of the offseason on Friday, as multiple reports say that they have signed outfielder Jason Heyward. 

Heyward was the top free agent outfielder on the market, and the Cubs had to compete with numerous teams, including the Washington Nationals, St. Louis Cardinals, and Los Angeles Angels of Anaheim, to land his services. 

Gordon Wittemeyer of the Chicago Sun-Times was the first to report the deal as done, with Ken Rosenthal of Fox Sports and Jon Heyman of CBS Sports confirming the initial report. 

According to Peter Gammons of MLB Network, Heyward's deal is an eight-year pact worth $184 million, with an opt-out clause after the third season. 

Heyward represents not just an offensive upgrade for the Cubs in their outfield, but also a defensive one as well. Heyward is arguably one of the best corner outfielders in baseball, winning a Gold Glove during the 2015 season with the Cardinals, and he has the range and speed to play center field, which the Cubs could potentially have him do. 

At the plate, Heyward had a stellar year, batting .293 with 13 home runs and 60 RBI while stealing 23 bases for the Cardinals. His offensive production was a big part of the reason why the Cardinals were able to win 100 games and take down a hotly-contested NL Central Division championship. 

According to reports, the Cubs aren't done dealing yet, as they could still be in the market for another starting pitcher. The Cubs could also potentially add another piece via free agency, but a trade would likely need to happen in order to free up salary space to do so.
