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
Called upon for Opening Day start
Manager Scott Servais said Monday that Castillo will start the Mariners' March 28 season opener versus the Red Sox at T-Mobile Park, Ryan Divish of The Seattle Times reports.
ANALYSIS
The Mariners have better choices than most teams to take the ball Opening Day, but Castillo always loomed as the obvious option. The 31-year-old right-hander posted a 3.34 ERA and 219:56 K:BB over 197 innings covering 33 starts for Seattle in 2023.

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.

Encouraged by early velocity
Castillo, who fired a couple of 96-mph fastballs during his Cactus League debut Monday against the Reds, is encouraged he has that level of velocity early in camp, Daniel Kramer of MLB.com reports. "It's telling me that I'm healthy," Castillo said. "We're going to continue to be in the same routine, and hopefully that velocity will keep going up."
