2023 Projections
2023 Fantasy Outlook
Castillo usually gives you a little bit of everything, including seven wins, nine holds and seven saves last season with Seattle. Historically, strikeouts and solid ratios have been part of the package too, but the right-hander's strikeout rate dropped 8.3 percentage points to a career-low 23.9% last year. Castillo's walk rate went in the wrong direction too, though he's always had trouble with his control, walking over three batters per nine innings for his career. On the plus side, he allowed a mere 30.6% hard hit percentage (95th percentile) with a career-best home run rate (0.8 HR/9). Castillo should reprise his high-leverage role for Seattle in 2023, but Paul Sewald and Andres Munoz are likely ahead of him in the pecking order for saves. Read Past Outlooks

Takes third loss Wednesday
Castillo (7-3) was charged with the loss against the White Sox on Wednesday, allowing an unearned run on one hit over one inning while recording a strikeout.
ANALYSIS
Castillo was sharp and efficient while throwing 10 of 15 pitches for strikes, but the RBI groundout he surrendered to Gavin Sheets in the eighth inning snapped a 6-6 tie and gave the White Sox a lead they wouldn't relinquish. The veteran right-hander has now uncharacteristically allowed a run in three straight appearances, but he still sports a solid 3.50 ERA and 1.21 WHIP in addition to his seven victories, seven holds and six saves.

Past Fantasy Outlooks
2022
2021
2020
2019
Castillo opened 2021 in Tampa Bay as the team's primary closer, a role that wasn't planned as the Rays like to mix and match in the ninth inning, but one he held out of necessity due to the vast number of injuries that affected the bullpen early on. He earned 14 saves before the injured Rays relievers got healthy and Tampa Bay surprisingly traded him to Seattle. Castillo logged only two saves in six chances with the Mariners as the third option in their closer committee, but he posted a solid 2.78 ERA and 0.98 WHIP for the season with a career best 32.2% strikeout rate and 7.3% walk rate. His velocity dropped a few ticks to 94.7-mph and he allowed a career worst 1.4 HR/9, but there's still plenty to like in his profile. Castillo will likely get some save chances, but the likelihood of surpassing the 16 saves he logged last season are slim, as Seattle like to use a committee and has a tall high-leverage ladder.
