The Chicago Cubs made a huge move last offseason by acquiring superstar outfielder Kyle Tucker. But Tucker is headed for free agency, so the Cubs are going to need to make an even bigger move to re-sign Tucker to a new deal this winter.

And that’s not going to be an easy task. The biggest contract the Cubs have ever signed a free agent to was an eight-year, $184 million deal signed by Jason Heyward. And Tucker is projected to double that deal in value.

MLB insider Jim Bowden of The Athletic recently projected the Cubs star outfielder would sign a 10-year deal worth $427 million this winter.

“Despite a season that was marred by injury and inconsistent performance, Tucker is expected to be the highest paid free agent in this year’s class, with most analysts believing he will get between $400 million and $500 million based on the recent contracts given to Vladimir Guerrero Jr. ($500 million; Blue Jays) and Juan Soto ($765 million; Mets),” Bowden wrote. “Even in a season that saw Tucker dealing with multiple injuries, he was able to impact the game in all areas thanks to his hit tool, power, defense, arm and speed.

“In 136 games for the Cubs, he hit .266/.377/.464 with 22 homers, 25 stolen bases and a near 1:1 walk-to-strikeout ratio (87 walks and 88 strikeouts). Teams view him as a complete player who will be a threat to hit 30 homers and steal 30 bases every season.”

Tucker is one of the best pure hitters in the league. If it weren’t for Juan Soto and Vladimir Guerrero Jr. landing contracts worth at least half a billion dollars, Tucker’s value wouldn’t be this high, but that pair of stars reset the market.
