The Mariners are signing starting pitcher Luis Castillo to a five-year, $108 million contract, ESPN’s Jeff Passan reports. The deal includes a vesting option that could make the full contract six years, $133 million.
Seattle acquired Castillo from the Reds at the trade deadline in a blockbuster deal, giving up Noelvi Marte, Edwin Arroyo, Andrew Moore and Levi Stoudt. Marte and Arroyo are both on MLB Pipeline’s Top 100 prospects list and are ranked second and third in the Cincinnati farm system.
Since the deal, Castillo has instantly become the Mariners ace.
