PHOENIX — No translation was required for Hyeseong Kim’s appraisal of Roki Sasaki’s new slider.
“Good,” Kim stated in English.
Ok for the Korean infielder to swing on the pitch and miss in a dwell batting follow session towards Sasaki on Saturday.
Challenge Roki is underway at Camelback Ranch, the ninth-inning sensation of the Dodgers’ most up-to-date World Sequence run working to solidify a spot within the workforce’s rotation.
Sasaki is armed with two weapons that made him a dominant pitcher in Japan, in addition to the nation’s most anticipated baseball export since Shohei Ohtani: a 100-mph fastball and Wiffle-ball-like forkball.
Final yr, greater than 83% of pitches he threw have been both fastballs or forkballs. Discovering success as a significant league starter will likely be borderline not possible with simply two efficient pitches, which is why the 24-year-old Sasaki is trying to include into his arsenal a slider or cutter, or possibly each.
Sasaki stated he junked the slower variation of the slider he threw final season, which was not solely hittable but additionally contributed to shoulder issues that sidelined him for 4 months. He’s now experimenting with a quicker model of the pitch he threw earlier in his profession in Japan, with a spiral spin.
“I believed the slider I threw final yr wasn’t excellent,” Sasaki stated in Japanese. “In actuality, the outcomes weren’t excellent, both.”
Earlier than he was positioned on the injured record final yr, Sasaki made eight begins during which he posted a 4.72 ERA.
The swing-and-miss by Kim on Saturday was a constructive signal, however Sasaki stated he nonetheless doesn’t have a transparent imaginative and prescient for a pitch that can transfer away from right-handed hitters, whether or not it will likely be a slider or a cutter or one thing in between. Sasaki stated he additionally plans to combine in a two-seamer.
By including a slider or cutter and a two-seamer that travels in the other way, Sasaki stated, “I feel it is going to carry my fastball and forkball to life.”
Stated Dodgers basic supervisor Brandon Gomes: “If he’s executing the fastball and break up the way in which he’s able to, with what he’s executed up to now, it’s an incredible basis. Something on prime of that’s simply going to make issues tougher for opposing hitters.”
Sasaki downplayed the magnitude of the modifications he’s making, saying he began engaged on the brand new pitches final yr. No matter he finally ends up including to his pitch combine, consolation will likely be a significant precedence.
“As a lot as doable, I don’t need it to have an effect on my present pitching movement,” he stated.
Sasaki confirmed why that was necessary to him as he pitched to Kim and minor-league catcher Seby Zavala. His fastball touched 98.6 mph.
Reflecting on his first season with the Dodgers final yr, Sasaki stated, “It wasn’t a lot about coming to the key leagues and extra about me stumbling.”
He believes that after he begins competing at this stage with none bodily impairments, he ought to be capable of see the issues he has to treatment as a way to excel.
“My purpose is to proceed pitching in order that I can see these challenges,” Sasaki stated.
Returning within the remaining week of the common season as a reliever and having fun with success as a more in-depth within the playoffs final yr was useful, Sasaki stated.
“Reasonably than end on the finish of the spring (after I was positioned on the injured record), it was clearly higher to complete in a great way within the postseason,” he stated. “It’s now simpler to think about one thing good. I used to be capable of see one thing good, so in that sense, I feel I’m capable of pitch a little bit extra relaxed.”
Sasaki can also be drawing inspiration from a go to he made within the winter.
Again in Japan in December, Sasaki held a baseball clinic for 170 elementary faculty college students within the coastal city of Suzu, which was devastated by an earthquake in 2024. He stated he reached out to the town in the midst of final season to make preparations. He ran with the youngsters, watched them play catch and answered their questions. Earlier than they left, he handed every of them an autographed baseball.
Sasaki might relate to the youngsters, as his personal life was formed by a significant earthquake. When he was 9, his childhood dwelling in Rikuzentakata was swept into the ocean by a tsunami. He misplaced his father and a set of grandparents within the catastrophe.
“That was my first time collaborating in a baseball clinic,” Sasaki stated. “It’s an expertise you don’t normally have. I obtained totally different sorts of energy from the youngsters.”
He’s now channeling that into a brand new arsenal, a brand new season and probably a brand new id as a pitcher.
