Nate Pearson Background

Pearson has been somewhat of a journeyman during his time in professional baseball. The former first-round draft pick has spent time in Toronto and Chicago before signing with the Houston Astros last season. He began the season on the injured list while recovering from offseason right elbow surgery but returned to action in May. With Houston, he posted a 3.60 ERA in 20 innings pitched across 16 games. On July 19, Pearson was designated for assignment. A few days after his designation, the Royals traded for Pearson in exchange for pitching prospect Max Martin. 

Pearson's 2026 Season

Total: 42 G, 46 IP, 37 H, 26 BB, 41 K, 4.11 ERA, 1.370 WHIP, 4 Saves

Royals: 26 G, 26 IP, 21 H, 14 BB, 25 K, 4.50 ERA, 1.346 WHIP, 3 Saves

Pearson hit the ground running after coming to Kansas City. In his first 20 appearances with the Royals, he pitched 21 innings with only 1 earned run, 20 strikeouts, and 11 baserunners allowed, good for a 0.43 ERA and a 2.62 FIP. Pearson’s emergence into the Kansas City bullpen was a much-needed spark for the bullpen that had posted a 5.30 ERA before his arrival. 

Pearson slightly adjusted his pitch mix by leaning more on his fastball and sinker. In Kansas City, he increased his fastball usage from 40.5% to 48.1% and his sinker from 9.5% to 16%. To offset this adjustment, he decreased his slider usage from 36.1% to 21.6%.

Pearson was unable to maintain the near-perfect start to his Royals tenure. In September, he had a stretch of five consecutive appearances with at least one earned run, during which his Royals ERA ballooned to 4.62 and his FIP to 3.77. 

Pearson stands out with his fastball velocity and extension. His extension was the highest among Royals pitchers, and only Steven Cruz has a faster fastball velocity than Pearson. His TJStats Stuff+ of 107 topped all Royals pitchers other than Craig Kimbrel and Anthony Gose (who had a much smaller sample). Despite this near-elite combination of Statcast metrics, Pearson was below average in strikeout, walk, and CSW (called strike + whiff) rates. Pearson’s success has stemmed from his ability to limit hard contact and induce ground balls.

Why the Royals Should Offer Him Arbitration

He was a standout pitcher in an otherwise disastrous bullpen for the Royals in 2026. His combination of fastball velocity, stuff, and extension is unmatched in any other option currently in the Royals system. With Estévez sidelined by injury, the Royals bullpen was never able to find its footing in high-leverage late-inning situations. Pearson was given opportunities to pitch in situations, earning three saves and six holds, that could prime him for competing for that role in 2027.

Pearson also showed he can prevent runs for long stretches during the season in his first 20 appearances (TJStats summary below) for the club. Over that period, he greatly reduced his walk rate to only 8.5% with an increased strikeout rate of 24.4%. If he can bring that level to the Royals in 2027, he will likely become an integral part of an improved bullpen that will hopefully help see the Royals return to post-season action.

Why the Royals Should Non-Tender Him

His ability to perform at a high level over extended periods can be offset by consecutive struggles to get batters out. With a low strikeout rate, he may become overly reliant on his defense to put players out. With a high walk rate, baserunners can easily pile up. Pearson’s Location+ is also the lowest of all Royals pitchers with at least 10 innings pitched, which contributes to his poor strikeout and walk rates. Despite his excellent stuff on his pitches, they become less effective if they are not properly placed. For a pitcher entering his thirties, the time may have passed to hope for a noticeable increase in command.

His $2 million contract estimate may be noteworthy for a small-market team like the Royals. Only three relievers for the Royals made at least that much in 2026, none of whom were on the active roster to finish the season. While a seemingly low value when compared to some contracts throughout the league, every million is noticed in a lower payroll, and the Royals may not be interested in paying for upside that has not yet materialized at the major-league level.

Prediction: The Royals Keep Pearson

His overall performance stood out enough to warrant a return next season. With so many underperforming relievers last season, there will likely be many new faces in the Royals bullpen. There will be players that are likely ahead of him in non-tender priority, and it will be impossible to replace everybody in one offseason. Pearson showed enough during his time in Kansas City with his stuff, velocity, and extension to give him considerable upside for next season. If the team can isolate the issues that plagued him at the end of the season, Pearson could be in contention for a role at the back end of the bullpen, depending on any potential offseason acquisitions.
