Below is a comprehensive breakdown of Peterson's key statistical performance metrics over his recent campaigns, showcasing his evolution into a dependable Major League starter.
| Season | Team | W-L | ERA | IP | SO | WHIP | GB% |

From Post-Surgery Rebound to Rotation Anchor
To fully understand the current value of David Peterson stats, one must look back at his pivotal career pivot. Following major hip surgery in late 2023, Peterson returned in mid-2024 to post a career-best 2.90 ERA, proving to the Mets' front office that he could handle top-of-the-rotation pressure. His knack for escaping bases-loaded jams and keeping the ball on the ground quickly became his signature.
Entering the 2026 season, Peterson has focused on maintaining his durability and refining his five-pitch mix. While some analysts pointed to his 2024 FIP (Fielding Independent Pitching) as a sign of impending regression, his subsequent performances in 2025 and 2026 have silenced skeptics. He has successfully stabilized his walk rate (BB/9) while keeping his groundball rate comfortably above the league average of 42%.
Fantasy Baseball Value and Sabermetric Breakdown
For fantasy baseball managers and sports bettors, Peterson's underlying metrics offer deep utility. His primary weapon remains a devastating slider, which generates a whiff rate near 35%, complemented by a heavy sinker that forces routine groundouts. This combination makes him highly effective against right-handed hitters, who historically struggled to elevate his low-and-away breaking stuff.
Key advanced metrics driving his 2026 performance include:
- Groundball Rate (GB%): Consistently hovering around 50%, keeping home run damage to a minimum in hitter-friendly parks.
- Hard-Hit Percentage: Staying in the 38th percentile or better, preventing opponents from barrel-rolling his fastballs.
- Left On Base Percentage (LOB%): While his career average sits high, his ability to execute pitches with runners in scoring position remains elite.

The August Push and Peterson's Future in New York
As of August 2, 2026, the Mets are locked in a fierce battle for the postseason. Peterson's performance over the next two months will heavily dictate the team's playoff seeding and bullpen usage. With the trade deadline recently passed, the coaching staff is relying on Peterson to consistently pitch into the sixth inning to preserve high-leverage relief arms.
Furthermore, Peterson's contract situation and service time make this late-season stretch critical for his long-term future. Pitchers who can reliably generate groundballs and log 150+ innings are premium assets in today's market. Continued excellence in his upcoming starts will position him for a lucrative extension or a prominent role in the Mets' future postseason rotations.
