Dallas Keuchel has a new team.

The 31-year-old left-hander agreed Saturday to a three-year, $55.5 million contract with the Chicago White Sox, a source told ESPN’s Jeff Passan. The deal includes a vesting fourth-year option worth $18.5 million.

The Post’s Joel Sherman notes that Scott Boras clients Gerrit Cole, Anthony Rendon, Stephen Strasburg, Mike Moustakas and Keuchel have now combined for $933.5 million in guaranteed money on free-agent deals in the past several weeks. Hyun-jin Ryu and Nick Castellanos are expected to move that over $1 billion this offseason.

Keuchel, who won the Cy Young Award with the Astros in 2015, has an 84-71 mark with a 3.67 ERA in his eight MLB seasons. Last season, the veteran signed a roughly $13 million, one-year deal with the Atlanta Braves in June, going 8-8 with a 3.75 ERA for the NL East champions.

The White Sox have been busy this offseason. The Keuchel deal follows the White Sox signing another veteran lefty, Gio Gonzalez, to a one-year, $5 million deal, which was finalized on Friday.

They kicked off free agency by signing catcher Yasmani Grandal to a four-year, $73 million deal in November. They also re-signed All-Star Jose Abreu to a three-year, $50 million contract later in the month.

Chicago acquired outfielder Nomar Mazara in a trade and snagged catcher James McCann.
