It was all the time going to be tough for Roki Sasaki to dwell as much as the sky-high expectations that adopted him from Nippon Skilled Baseball to the Main Leagues. Certainly, he has regarded each bit the work in progress the Dodgers mentioned he was once they signed him this previous offseason.
Sasaki entered the season as MLB Pipeline’s No. 1 general prospect, a sign of how these across the recreation considered his instruments, upside and potential massive league affect. Via eight begins, the 23-year-old right-hander has gone 1-1 with a 4.72 ERA with 24 strikeouts and 22 walks in 34 1/3 innings.
There have been some encouraging moments, however Sasaki’s rising pains have stood out towards the backdrop of a Dodgers crew that has ambitions of defending its World Sequence title. His newest begin was the worst of his younger Main League profession, as he allowed a season-high 5 runs throughout 4 innings vs. the D-backs on Friday night time at Chase Subject.
The day after, supervisor Dave Roberts made it clear that the Dodgers intend to let Sasaki work issues out on the massive league stage.
“There’s nothing extra impactful than going by way of a specific expertise,” Roberts mentioned. “He is going by way of some struggles proper now. Main League hitters let you know what changes you’ll want to make. Coaches can let you know issues. He can assume some issues. However in the end, you can also make changes, and he’ll make changes, given how the hitters reply. I feel you study that by doing that right here.”
“I do not assume {that a} Minor League stint is in any of our minds proper now,” Roberts mentioned. “However I do assume that this studying up right here could be very, very invaluable.”
One of many greatest classes discovered has been about Sasaki’s arsenal. His splitter might be devastating. His slider has been considerably of a nice shock. However he must have his four-seamer in fine condition to make the entire combine work, and it simply has not been there.
Listed here are some takeaways from what we have seen from Sasaki’s fastball:
The velo
The homework task that Sasaki gave groups when he was posted this previous offseason is extra of a long-term venture in follow. As a refresher, he requested golf equipment to determine why his velocity dipped in 2024 and to current a plan to make sure that the decline wouldn’t proceed.
Sasaki’s fastball has averaged 96 mph, good for eightieth percentile amongst certified Main Leaguers, based on Statcast, nevertheless it’s not the triple-digit warmth he was slinging in his NPB days.
“Simply actually nonetheless on this means of discovering out what the basis trigger [is], working with my coaches, speaking to individuals about this,” Sasaki mentioned Friday by way of interpreter Will Ireton. “I am not fairly precisely certain and may’t actually state precisely the only motive.”
The swing-and-miss
With out as a lot velocity and life on the fastball, it turns into extra hittable. When opponents are swinging at Sasaki’s fastball, they’re making contact. His general 20.4 p.c whiff charge ranks within the 18th percentile, and hitters are solely lacking on 10.1 p.c of their swings towards the four-seamer.
A giant a part of the rationale why Sasaki initially started throwing his slider extra towards massive league hitters is as a result of he realized they had been hitting his fastball laborious. That was a constructive growth within the sense of him trusting his total arsenal, however the underlying drawback stays.
However as Roberts sees it, all of it boils all the way down to …
The command
Sasaki has mentioned he is not dialing again his velocity for higher command, which has improved from his first handful of begins.
However since he is not throwing as laborious as he is accustomed to, finding his fastball has turn into much more vital. Sasaki must constantly set up his four-seamer within the zone to be able to make his splitter and slider aggressive pitches.
“While you’re throwing mid-90s, 94 [mph], then you definitely obtained to essentially command the baseball. In order that’s what we’re going to work on as a gaggle,” Roberts mentioned. “Roki understands that. And that is nonetheless his first season right here, so there must be some grace, as he’s sort of studying this league and sort of getting his footing.”
