2026 Projections
2026 Fantasy Outlook
The beginning of Sasaki's tenure with the Dodgers was rocky, to say the least. The 24-year-old posted a 4.72 ERA, 1.49 WHIP and 29:22 K:BB over 34.1 innings covering his first eight starts of the season before landing on the injured list with a right shoulder impingement. Sasaki would not make another start with the big club in 2025, finally returning as a reliever in late September after a mechanical adjustment unlocked his stuff. He then thrived out of the bullpen in a couple late regular-season appearances and in the playoffs. Sasaki will be given another chance to start in 2026, and the upside remains tantalizing. That said, he'll be a major wild card for fantasy purposes from a performance standpoint, and even if he pitches well, the workload could be relatively limited. Read Past Outlooks
Signed a one-year, $760,000 contract with the Dodgers in March of 2025.
Shaky again in second spring start
Sasaki allowed four runs on two hits and three walks while striking out one batter over two innings in a Cactus League start versus Cleveland on Tuesday.
Analysis
Sasaki began his outing in disastrous fashion, allowing two walks and a single before serving up a grand slam to Kyle Manzardo. After the Japanese hurler walked the next batter, he was pulled without having recorded an out. Under spring training rules, Sasaki was allowed to re-enter the contest in the second frame and looked infinitely better after his return, retiring the final six batters he faced. Despite the strong finish, this was a second consecutive concerning appearance for the young hurler, especially in terms of control -- through two starts, he's thrown just 38 of 81 pitches for strikes while walking five batters across 3.1 innings. Still, manager Dave Roberts suggested after the exhibition that Sasaki isn't in danger of missing out on a rotation spot to begin the campaign, stating, "I think it can change, but I don't think it's going to change before we break (camp). I think that, keep building him up. We see him as a starter and giving him every opportunity for success," per Fabian Ardaya of The Athletic. Roberts added, "I don't think there are concerns. There just has to be continued progression." It sounds like the team is going to give Sasaki a decent amount of runway to work out his struggles and remain in the big-league rotation, though he'll ultimately need to provide much better results to keep that role over the course of the regular season.

2025 Fantasy Outlook
As a 20-year-old NPB phenom, Sasaki threw a perfect game and followed that up with eight perfect innings in his next start. Three years later, he's set to get his shot at the MLB level. He's sure to generate a ton of interest due to his youth and potential, but there's plenty of downside with Sasaki as well. First and foremost are durability concerns. He topped out at 20 starts and 129.1 innings in 2022 and has averaged 16.5 starts and 101 innings over the last two years while battling oblique and arm issues. He's taking steps to address those concerns by decreasing his fastball velocity and pitching to contact more often, with his fastball now sitting in the upper 90s instead of triple digits and his K% falling from 39.1% in 2023 to 28.6% in 2024. That could mean Sasaki is simply getting worse rather than making a conscious decision to stay healthy, as it did result in a career-high ERA - but when a 2.35 ERA represents a career high, expect MLB teams to remain very interested.

Gets endorsement as team's closer
Manager Dave Roberts said Tuesday that Sasaki is "definitely the primary option now" to close games for the Dodgers, though the skipper noted that the rookie's availability will be contingent on his workload, Alden Gonzalez of ESPN.com reports. "We have to win X amount of games [to secure a championship], and he's not going to close every game," Roberts said of Sasaki. "It's just not feasible, so, you've got to use other guys."

Primary option in save situations
Sasaki will operate as the Dodgers' primary option in save situations, Dave Roberts told Jack Harris of the Los Angeles Times this week.
Analysis
Sasaki recorded a one-out save in Game 2 of the NLDS against the Phillies after retiring Trea Turner with runners on the corners and two outs in a 4-3 win Monday. It was the first time in his MLB career that he was called upon in the middle of an inning, but it's worth noting that Sasaki has finished three of the Dodgers' four postseason games so far.
