Roki Sasaki is finding his footing for the Dodgers with a new offspeed pitch

What happened

Roki Sasaki introduced a second offspeed pitch to his arsenal roughly a month ago, and per FanGraphs, the results since then have been meaningfully better — improved command and sharper velocity accompanying the new offering. The development matters because the numbers through his first 10 starts had not made a compelling case for patience.

Why it matters

FanGraphs reports that Sasaki carried a 4.59 ERA and a 5.04 FIP across 51 innings through those 10 starts. Taken at face value, those figures could reasonably suggest the 24-year-old right-hander had not moved far from where he stood during last year's abbreviated rookie campaign — a season that ended early after he missed four and a half months with a shoulder impingement. Per FanGraphs, his early-season outings called last year's struggles to mind, and some observers had wondered whether time in Triple-A or the bullpen might be the more productive path. He found some success in the bullpen last fall, which made that argument at least plausible.

The repertoire change shifted the conversation. Per FanGraphs, the improvement over the last month has been driven not only by the new pitch itself but by better command and velocity working alongside it — a combination that tends to compound rather than simply add. A pitcher with a deeper arsenal who is also executing more precisely is a different proposition than one who has merely added a grip to his repertoire and hoped for the best.

FanGraphs also notes that the timing is particularly useful for the Dodgers, who are once again managing the rotation without full availability across their staff. The source text references the absences of Tyler G — the name is truncated in the available material — but the broader point is clear: Sasaki's upward trend arrives at a moment when Los Angeles has reason to welcome it.

The numbers

### What does the season line actually tell us?

The 4.59 ERA and 5.04 FIP in 51 innings over 10 starts are the figures FanGraphs cites as the before-picture. They are worth keeping in view not as a final verdict but as a reference point — the baseline against which the recent improvement is being measured. A trend is only legible if you can see what it is trending away from, and those numbers provide that anchor.

The Dodgers themselves sit at 100-62 (.617), first in the NL West, and have won three straight. That record reflects a roster constructed with considerable depth, but a rotation piece developing mid-season is not incidental to a club with October in mind. The 4.59 and 5.04 are the numbers that made the question worth asking; the last month of starts, per FanGraphs, is the answer that has begun to take shape.

Where the club stands

### Is Sasaki starting Friday?

Per the schedule, yes — Sasaki is the probable starter for Friday, June 5 against the Los Angeles Angels at UNIQLO Field at Dodger Stadium, opposed by Reid Detmers. That gives the recent stretch of reportedly improved pitching an immediate and concrete test: a home start, with the Dodgers coming off a road series in Arizona.

Before that, Los Angeles plays Wednesday, June 3 at Chase Field with Shohei Ohtani taking the ball against Zac Gallen, followed by Thursday, June 4 at Arizona with Justin Wrobleski opposing Ryne Nelson. The Dodgers enter that stretch at 100-62, leading the NL West, on a three-game winning streak.

A 100-win pace is the kind of number that can make internal roster questions feel like a luxury problem — and in some ways it is. But the Dodgers have been here before, and they understand that October rotations are assembled from whoever is actually pitching well in June, not from whoever was projected to pitch well in March. FanGraphs frames Sasaki's improvement explicitly as timely for the club, and a team at 100-62 is not a team that takes rotation depth for granted.

What we don't know yet

The FanGraphs piece is an analytical report, not a club announcement, and several things remain unresolved. The source text is truncated at the mention of the Dodgers carrying on without "Tyler G" — the full name and the nature of that absence are not available from the material at hand, so no claim about that situation can be made here.

More broadly, the improvement FanGraphs describes spans roughly a month of starts. Whether the command and velocity gains hold, whether the second offspeed pitch continues to play as described, and whether the 4.59 ERA and 5.04 FIP move in a more favorable direction over the second half are all open questions. FanGraphs is characterizing a trend, not certifying a transformation.

The shoulder impingement that cost Sasaki four and a half months last season is part of the backdrop here, though the source makes no claim about its current relevance to his mechanics or how the Dodgers are managing his workload. That history is on the record; what it means for the rest of 2026 is not something the material addresses.

What to watch

Friday's start against the Angels is the most immediate measuring stick. Sasaki on the mound at Dodger Stadium, with a month of reportedly improved outings behind him and a new pitch in the mix, is about as clean a near-term test as the schedule provides.

Beyond Friday, the question is whether the FanGraphs framing — that Sasaki is putting it together — gets reinforced by subsequent starts, or whether the sample remains too limited to draw firm conclusions. A month of better pitching is a real signal. It is also, set against a 51-inning season line that still reads 4.59 and 5.04, a signal that is still in the process of establishing itself.

The Dodgers, at 100-62 and first in the NL West, are not a club in need of a rescue narrative. But a 24-year-old starter with a deeper arsenal and sharper execution is a different kind of rotation piece than one still working through early-season inconsistency — and the gap between those two versions of Roki Sasaki is precisely what FanGraphs is reporting has begun to close.
