Yoshinori Sato confident he can fix Fujinami’s control problems — 5ch: ‘He’s the next victim’

The story

Shuntaro Fujinami, recently informed he’s been cut from the roster, is the subject of fresh comments from Yoshinori Sato — known as the “mentor” who developed the command of pitchers like Masahiro Tanaka and Yu Darvish. In a Yahoo News article, Sato said he’s “confident he can fix [Fujinami’s] control issues” and suggested that “his previous coaches probably just couldn’t coach him properly.” The remarks split a 5ch thread between posters debating the technical root causes and those arguing the real problem is Fujinami’s own refusal to take advice. Some pointed out his control was already shaky back in high school, while others suggested he switch from a three-quarter arm slot to a full overhand delivery — the debate never settled on one answer.

Fujinami Shuntaro, cut from the roster — Yoshinori Sato, “mentor” to Tanaka and Darvish: “There’s a prescription for overcoming his control problems”

Apparently he's not even willing to listen to advice, so it doesn't matter how good the coach is — it's hopeless. Unless he genuinely respects the guy, like 'brainwash'-level respect where he'll actually listen, nothing changes.

Re: #13
He'd probably listen now, though.
14AnonymousOct 7, 2026 11:50
This is the classic 'I alone can tame and control the monster,' says the smug scientist — right before getting eaten first.

Sounds like the plot of some American movie lol
25AnonymousOct 7, 2026 11:53
What would've happened in the timeline where nobody tried to fix his in-step delivery? (stepping across his body toward home plate)
57AnonymousOct 7, 2026 12:08
Re: #25
Fujinami hasn't changed at all since he joined the team, honestly. The in-step thing and Kanemoto's '160' remark have nothing to do with each other.
30AnonymousOct 7, 2026 11:54
He doesn't listen to anybody, so it's hopeless lol
59AnonymousOct 7, 2026 12:08
Re: #30
Nah, Fujinami does listen — he just drops it again almost immediately.
32AnonymousOct 7, 2026 11:54
Fujinami's ideal self is stuck in his high school days — back then he could control the ball even swinging his arm freely.
34AnonymousOct 7, 2026 11:55
Re: #32
Your body changes as you age, and most guys change through getting hurt along the way — but this guy's needlessly durable, so he never even gets that kind of wake-up call.
33AnonymousOct 7, 2026 11:54
His velocity doesn't even top 155 km/h anymore, so he's turning into a pitcher with zero selling points.
38AnonymousOct 7, 2026 11:56
Re: #33
If no control is acceptable, there are guys throwing 160 km/h in the independent leagues too.
41AnonymousOct 7, 2026 11:57
Until Kuroda chewed him out, I don't recall him being treated as that much of a 'no control' case.
56AnonymousOct 7, 2026 12:08
The Athletics probably used him best, honestly.
68AnonymousOct 7, 2026 12:11
Re: #56
The Athletics just set the mitt dead center and had him throw right down the pipe. When Fujinami throws comfortably like that, even a hittable pitch down the middle doesn't get hit much. I think that's genuinely the right approach for him.
60AnonymousOct 7, 2026 12:08
Whenever he gets coached into prioritizing control, he gets pounded even by farm-team hitters, so he ends up back to his usual wild pitching — that's been Fuji's pattern for years, right? And he probably figures getting hit all over the place is worse than being erratic-but-fast with the occasional wild pitch.
69AnonymousOct 7, 2026 12:12
Re: #60
Not just the last few years — it's been like that since his Hanshin days.
61AnonymousOct 7, 2026 12:08
Isn't it hopeless unless he drops that three-quarter, 'kamikaze-against-right-handers' delivery?
70AnonymousOct 7, 2026 12:12
Re: #61
Exactly. He should switch to a full overhand delivery. That way, even if a pitch slips out, it won't sail into the batter, so he can cut loose at full effort.
62AnonymousOct 7, 2026 12:09
Why does everyone convince themselves 'I'm the one who can fix Fujinami'? He's the next victim.
74AnonymousOct 7, 2026 12:13
Re: #62
I guess velocity and home-run stuff are just irresistible to coaches too.
67AnonymousOct 7, 2026 12:10
With Fujinami it's less about what's wrong and more about what changed. Through his third year as a pro out of high school, he was at Matsuzaka/Tanaka level.
72AnonymousOct 7, 2026 12:12
Re: #67
Even back in high school his pitches were all over the place — he had no control then either.
73AnonymousOct 7, 2026 12:12
So his Osaka Toin High School days were the real anomaly, huh.
78AnonymousOct 7, 2026 12:15
Re: #73
Guys who only ever do practice they're told to do never develop self-direction. For guys like that, you can't hand them autonomy as pros either — you need a coach glued to their side running practice all the way to retirement. It's a vicious cycle, because the more talented a guy is, the longer he can coast purely on assigned practice.
82AnonymousOct 7, 2026 12:16
If he could still top 160 km/h, I'd get wanting to fix him somehow — but a no-control guy who can't even hit 155 has no value. And his salary's quietly pretty high too.
104AnonymousOct 7, 2026 12:24
Re: #82
That's because he was throwing with an AI-coached, control-focused form back then. And he *still* had no control lol
86AnonymousOct 7, 2026 12:18
If he's still at the stage of fixing his flaws one by one at age 32, how has he even been making a living as a pro this whole time?!
92AnonymousOct 7, 2026 12:19
Re: #86
Because his talent far exceeds even Ohtani's.
91AnonymousOct 7, 2026 12:19
Like Iwamoto said, I feel like the only option left is to give up on the overhand delivery entirely and go full sidearm with the wrist laid flat.
94AnonymousOct 7, 2026 12:20
Re: #91
Even sidearm, if a pitch slips out it'll still head toward the batter. Switching to overhand is better — there's no point sticking with three-quarter.
96AnonymousOct 7, 2026 12:21
Re: #91
Pretty much anyone could come up with this idea — so why hasn't anyone tried it yet? Is there some reason?
112AnonymousOct 7, 2026 12:33
Re: #91
Sounds like it'd just produce a Reiwa-era [modern-day] Hiramoto.
98AnonymousOct 7, 2026 12:23
He's not going to listen to anyone's advice anyway. I gave up expecting anything from this guy when I saw him going on variety shows nonstop during the offseason the year he went to the majors — sure, he'd put up some decent results, but he's not exactly in a position to be goofing around like that.
105AnonymousOct 7, 2026 12:26
Re: #98
He just doesn't have much drive to improve. Even when Ohtani treated him dismissively, he didn't seem to care much.
103AnonymousOct 7, 2026 12:24
He flat-out ignores even [Toshio] Enatsu, so there's no way he'd listen to guys beneath him.
107AnonymousOct 7, 2026 12:27
Re: #103
Well, you probably shouldn't associate with a convicted criminal anyway.
108AnonymousOct 7, 2026 12:27
Re: #105
The moment he can't put in the effort and starts making excuses about 'the yips,' that just shows he was that caliber of player to begin with. Sucks for anyone still holding out hope for him, but there it is.
115AnonymousOct 7, 2026 12:35
Re: #108
He can put in effort. The problem is he's got too much talent and no hunger. Ohtani got knocked out at the prefectural tournament; Fujinami won the spring-and-summer national high school championship double. He's still the fastest-throwing Japanese pitcher in the majors even now. I think deep down he's satisfied thinking, 'I'm actually number one, really.'

Background and Key Points of Debate

Yoshinori Sato is well-regarded as the coach who developed the command of pitchers like Masahiro Tanaka and Yu Darvish, and his technical instruction carries real credibility. Fujinami, meanwhile, drew attention for his blazing fastball as far back as his Osaka Toin High School days and still holds the record for fastest pitch thrown by a Japanese pitcher in MLB, yet his control problems have never been resolved, whether at the top or farm-team level, since turning pro. The thread split between those who believe “technical adjustments can still fix him” and those who argue the real issue is his attitude — that he won’t take instruction and lacks the drive to improve. The former camp points to concrete mechanical fixes, like switching from a three-quarter arm slot to an overhand or sidearm delivery; the latter notes that numerous coaches have already worked with him without results. It’s also worth noting that, according to some posters, his control was actually never stable even back in high school — so the view that “coaches ruined him after he turned pro” isn’t necessarily the whole story.
