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.

Yields two homers Friday
Sasaki allowed five runs on five hits and two walks while failing to record a strikeout over four innings versus the Diamondbacks on Friday. He did not factor in the decision.
ANALYSIS
This was Sasaki's first start on five days' rest, which may have contributed to his struggles. Arizona tagged him for three runs, including two home runs, in the first inning, though the Dodgers built up a lead before he exited the contest. He's now allowed six homers, all of which have come over his last five outings after he kept the ball down in three short starts to begin his major-league career. Sasaki is at a 4.72 ERA, 1.49 WHIP and 24:22 K:BB over 34.1 innings across eight starts this season. The Dodgers are likely to play it cautious with the 23-year-old right-hander moving forward, especially when the schedule allows for more rest between his starts.
