2024 Fantasy Outlook
The 31-year-old was acquired by the Mariners at the 2022 trade deadline and inked a five-year extension two months later; during his first full season with the team in 2023 he posted a 3.34 ERA, 1.10 WHIP and 219:56 K:BB in 197 innings. The campaign ended on a sour note, however, with nine runs allowed in Castillo's final two starts, including a 2.2-frame outing against Texas that eliminated Seattle from playoff contention. His strikeout and walk rates (27.3 percent and 7.0 percent, respectively) stayed stable, but his 1.3 HR/9 was the highest since his sophomore season in 2018. Castillo typically excelled at inducing groundballs while playing for the Reds with a career rate north of 50 percent, but he saw his flyball rate jump nearly nine points to 42.4 percent in 2023 while his groundball rate dipped below 40 percent. A barrel rate of 9.4 percent and hard-hit rate of 41.8 percent each represent career worsts, which also lines up with a 3.81 xFIP. Some regression may be in store for Castillo if he's unable to rein in those trends, but he's still likely a fairly safe bet for fantasy managers in 2024 given his track record. Read Past Outlooks
Begins season with loss
Castillo (0-1) took the loss against Boston on Thursday, allowing four runs on six hits and two walks while striking out five batters over five innings.
ANALYSIS
Castillo struck out two batters in a 1-2-3 first inning, but he didn't record any clean frames thereafter. The right-hander was stung by Rafael Devers' two-run homer in the third and followed by giving up a run in each of the next two frames. On a positive note, Castillo worked up to 91 pitches in his season debut and averaged 95.8 mph on his fastball, so he seems to be in good form despite the rough outing. He'll look to bounce back next week, as he is projected to make his next start at home against Cleveland.

Castillo was slowed by a sore shoulder in spring training, which in turn made him a great bargain in fantasy drafts. He made his 2022 debut May 9 and really got into a groove in the weeks leading up to the trade deadline, posting a 1.59 ERA, 0.97 WHIP and 41:10 K:BB in what would turn out to be his final five starts for Cincinnati. The Mariners spent a pretty penny in prospect capital to acquire Castillo and the right-hander paid immediate dividends, helping the team to the ALDS. With Castillo, the name of the game is the world-class changeup, set up by a good fastball at 97 mph. The skills only got better after the move to Seattle and the park upgrade is massive. It will be exciting to see what Castillo can do at age 30 in his first full season with a legitimate contender.
