The Red Sox and their new ace have a deal.

According to a team source, the Red Sox and Garrett Crochet have agreed to a long-term contract extension that will keep the left-hander in Boston for years to come.

The deal was first reported by ESPN’s Jeff Passan, who reports that the deal is for six years, $170 million and will begin in 2026. The contract also reportedly includes an opt-out after 2030.

Crochet was originally acquired in a blockbuster trade this past winter in exchange for four prospects, including recent first-round picks Kyle Teel and Braden Montgomery. But the 25-year-old was only under team control for another two seasons, and absent a deal Crochet would have been eligible for free agency after the 2026 season.

Extending Crochet has been a top priority ever since the pitcher first arrived, and negotiations had been ongoing throughout the offseason. Crochet had originally set an Opening Day deadline for any agreement, and when Thursday’s opener passed without a deal it appeared talks would be tabled until this coming offseason.

But evidently the two sides were close enough to continue discussions, and now they’ve managed to push things across the finish line.
