2026 Fantasy Outlook
Peterson was working on a strong campaign with a 2.83 ERA through 21 starts last season, but he fell apart down the stretch with 39 runs allowed in his final 41.2 innings. The end result was a 4.37 ERA, 1.37 WHIP and 150:65 K:BB over 168.2 innings, which was the largest workload of his big-league career by nearly 50 frames. Fatigue may have played a role in the decline, and it could also explain the small drop in velocity, with both his sinker and four-seam fastball losing a tick in 2025. Those two pitches have been Peterson's main offerings the past three years, and batters hit over. 300 against both pitches last season. The left-hander actually saw his groundball rate increase to a career-high 54.7 percent last season but also allowed a career-worst 45.9 percent hard-hit rate. Peterson will likely either need to get his fastball back on track or become more reliant on his breaking balls and changeup in order to return to the 2.90 ERA he posted over 21 starts in 2024. He showed more strikeout upside earlier in his career, but his fantasy ceiling is more limited given his 20.4 percent strikeout rate the past two years. Read Past Outlooks
