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. Read Past Outlooks

Nails down save in Game 1 win
Sasaki earned the save in Saturday's 5-3 win over the Phillies in Game 1 of the National League Division Series, allowing one hit and no walks with one strikeout in a scoreless ninth inning.
Analysis
After missing more than four months with a right shoulder impingement, Sasaki returned to the Dodgers in the final week of the regular season as a bullpen arm and earned a spot on the postseason roster. With Los Angeles' bullpen troubles this season, manager Dave Roberts deployed both Tyler Glasnow and Sasaki in relief in Game 1 on Saturday. After Glasnow and Alex Vesia combined for six outs, Sasaki took the ball in the bottom of the ninth and struck out J.T. Realmuto looking before allowing a double to Max Kepler. Sasaki then got Nick Castellanos to ground out and Bryson Stott to foul out to preserve the win. Sasaki hit triple digits with his fastball four times across 11 pitches in the ninth inning.

Latest Fantasy Rumors

Will pitch out of bullpen
Sasaki, who's set to return Wednesday from a shoulder injury, will pitch out of the bullpen once activated, manager Dave Roberts told Sonja Chen of MLB.com.
Analysis
The Dodgers have an open spot on their 40-man roster, so Sasaki only needs to be activated after missing more than four months due to a shoulder impingement. The Japanese hurler made seven appearances during a rehab assignment at the Triple-A level and pitched out of the bullpen in the last two, setting the stage for his new role in the majors. Sasaki tossed two scoreless innings with three strikeouts across his two relief outings.
