Correa tells The Athletic reporter that this is his last year with the Astros

From here

Bolded quote by Correa given last Saturday.

Alone among the active 2017 group, Correa is not under team control beyond 2021 (Justin Verlander, who is rehabbing from Tommy John surgery, will also be a free agent). In April, Correa told reporters he rejected an extension offer worth $120 million across six seasons and a second proposal worth $125 million across five. That proposal would soon be dwarfed by the deals struck by fellow shortstops Fernando Tatis Jr. ($340 million) and Francisco Lindor ($341 million). The Astros can afford to bring Correa back. But he speaks about this season with something approaching finality.

“My last year with the Astros, hopefully we can win another championship,” Correa says. “I can leave this great organization with two of them.”

Click harbors similar ambitions: “Our goal is to win as many World Series as possible over the foreseeable future,” he says. Whether those teams include Correa will depend on the volatility of the market and the willingness of Crane to win the bidding. In the interim, Correa remains a vital contributor to what Click describes as “the brotherhood that they have in the clubhouse.” The Astros, Click is quick to point out, have grown accustomed to hostilities on the road. The outpouring of disdain won’t derail them, he says. They aren’t built like us.
