Luis Castillo's Stats, Metrics, Game Logs, Projections & Rankings

Seattle Mariners Opening Day starting pitcher Luis Castillo struggled in his first game of the season on Thursday against the Boston Red Sox. Castillo pushed through five innings and allowed six hits, four runs, two walks and struck out five on the evening. The 31-year-old is coming off another strong season and managers should not be concerned as of now, despite spending a high draft pick on the right-hander. Castillo remains a top tier option with ability to rack up strikeouts and limits walks. He will look to get into the win column versus the Cleveland Guardians on Tuesday.

Seattle Mariners right-hander Luis Castillo, who was in the conversation for the American League Cy Young award for most of last year, threw 96 mph fastballs in the first inning of his Cactus League debut on Monday against the Cincinnati Reds. It was a significant rise compared to last year, when he was in the high-80s early on. It was a telling sign of Castillo's health, as he's typically a pitcher who grows slower into his velocity than most and who uses spring training to regain his feel rather than install offseason adjustments. "It's telling me that I'm healthy," Castillo said. His four-seam fastball held hitters to a .165 average and .384 slugging percentage in 2023 while generating a 33% whiff rate, an MLB-best among starters. Castillo's fastball/slider combo has made him an easy top-10 fantasy starter in Seattle.

Seattle Mariners starting pitcher Luis Castillo looked ready to go in his spring debut Monday, firing two scoreless innings in a 2-0 Cactus League win over the Reds.

Given the turbulent pitching landscape last season and his track record, Castillo has moved up into ace fantasy consideration for 2024.
