Roki Sasaki 2026 Fantasy Outlook: Starter Role Confirmed – Breakout or Bust in LA Rotation?

The Dodgers are at least talking him up as a member of their rotation. But in a related note, trade rumors are starting to swirl around Sasaki. For the sake of this column, we’ll take the Dodgers at their word that Sasaki will start.

If he does he won’t log much more than 135 IP - his career high is 129.1. So unless he spends time on the IL and/or gets some bullpen usage to manage his workload, expect 120-135 IP.

Even if he adds a pitch, his fastball and splitter - his main two offerings - need to be significantly better in 2026. He did throw a below-average slider about 14 percent of the time. Only the splitter was above average.

His success in the postseason was supported by a slight increase in ground balls and a sharp decline in fly balls. We wonder, ultimately, if he is better suited for late-game innings in the major leagues.

Realistic 2026 Fantasy Projections

It seems he will open the season as a starter and get every chance to succeed there. Based on his historical workload and his success in the late innings in the postseason we expect to see a shift to the bullpen at some point in 2026, though not necessarily for saves.

We have to believe that his talent will begin to show in the major leagues, which means greater strikeout rates and better control.

So how about: 102 IP, 97 Ks, a 3.87 ERA and a 1.19 WHIP? With Edwin Diaz at the back of the ‘pen it would be difficult to find saves unless an injury occurs.

But we have to assume, whether because of struggles or workload concerns, that Sasaki spends some time in the bullpen this season.

So Is Roki Sasaki A Breakout or Bust Candidate?

It would be satisfying to declare Sasaki - an undeniable talent - a breakout who will log 150+ innings with plenty of Ks, improved control and an expanded repertoire. But that’s a lot of ifs.

On the other hand, it would be too easy to predict a Sasaki bust in 2026. All arrows point that way. But he does have undeniable skills, he’s still a young pitcher and he’s in a good spot where expectations need not be sky high for him.

My final verdict is what I have to call a Brust. Some outings will look like a breakout and still others will reek of a bust. The truth will ultimately lie in the middle.

Updated 2026 SP Rankings & Draft Strategy

In this space, I often emphasize assuming “partial seasons” of most players. Never bank on 200 IP and accept 130-140 IP from an ace and hope for more. Sasaki almost certainly won’t sniff even 150 IP. If his draft slot allows you to get 100-110 IP, he might be worth considering but know that his time might be split between the rotation and bullpen.

If you don’t roster him at the draft and he struggles early in rotation, consider buying low for his move to the bullpen.
