Szymborski’s 2026 Booms and Busts: Pitchers

When you run a lot of projections, one thing you have to get used to is being very wrong, very often. The ZiPS projections generally run about 4,000 players every year, meaning you should expect around 800 players to either achieve their 90th-percentile projection or fall short of their 10th-percentile projection. Those hundreds of results will invariably be quite a distance away from the standard midpoint projections that you see.
As is my ritual, it’s time to run my two articles discussing my favorite booms and busts of the upcoming season. After looking at the hitters last week, today we turn our attention to the pitchers. But just to keep the ritual of humiliation fully transparent, we’ll start by looking at the pitchers I selected for last year’s booms and busts.
| Player | ERA | FIP | ERA- | WAR |
|---|---|---|---|---|
| Jack Leiter | 3.86 | 4.15 | 95 | 2.3 |

|---|---|---|---|---|
| Jacob deGrom | 2.97 | 3.64 | 74 | 3.4 |

Thank goodness I was wrong about Jacob deGrom, as he managed to have his first essentially healthy season in forever! I think it’s finally time for me to get off the Brandon Pfaadt train, meaning he’ll probably have his breakout this year. A real mixed bag, but it was overall a less bleak result than I had with the hitters! Read the rest of this entry »
