Mariners lock up Castillo to 5-year extension reportedly worth $108M
The deal is worth $108 million and could reach $133 million through a sixth-year vesting option, sources told Jeff Passan of ESPN.
Castillo's contract also features a no-trade clause for the first three years, according to Ken Rosenthal of The Athletic.
"I feel great," Castillo said in a press release. "Every baseball player wants to have a dream like this become a reality. I'm happy I was able to accomplish this with the Mariners, and I want to thank everybody in the organization for treating me so well."
The Mariners acquired the two-time All-Star in a blockbuster deal with the Cincinnati Reds before the trade deadline. He's posted a 2.83 ERA, 1.09 WHIP, and 64 strikeouts over 54 innings (nine starts) since joining Seattle.
Castillo, 29, was slated to become a free agent after the 2023 campaign.
