40 in 40: Unraveling Logan Gilbert's Efficiency Enigma
In the 2024 baseball season, Logan Gilbert emerged as a dominant force, leading the league in innings pitched and finishing second in strikeouts. His impressive performance earned him an All-Star selection and a top-six finish in the Cy Young voting. However, as the 2025 season unfolded, Gilbert's efficiency took a hit, despite maintaining similar or even better metrics on paper.
The question arises: Why did Gilbert's value to the team diminish? The answer lies in a subtle yet significant change in his pitch efficiency. Gilbert's innings per start decreased from 6.1 in 2024 to 5.1 in 2025, with a notable increase in pitches per plate appearance (P/PA) from 3.78 to 4.03. This seemingly minor adjustment had a substantial impact, adding approximately 22 innings to the season's workload.
Suspect #1: The Strikeout Enigma
One might assume that the surge in strikeouts could be the culprit. However, the math reveals a surprising twist. While Gilbert's strikeout rate increased by 4.9%, the additional strikeouts contributed only 0.087 P/PA, a relatively small fraction of the overall change. Interestingly, Gilbert's efficiency in strikeouts actually improved, saving him 0.030 P/PA.
Suspect #2: The Walk Conundrum
The walk rate increase from 4.6% to 5.8% also played a role, costing Gilbert 0.037 P/PA. This, combined with less efficient walks, resulted in a net effect of 0.056 P/PA, accounting for 22% of the overall change. However, these factors only explain a fraction of the mystery.
The Red Herrings: Misleading Clues
Two-strike struggles and command issues were initially suspected. However, Gilbert's efficiency with two strikes improved, and his command metrics remained stable. The increase in walks and balls in non-walk PAs was minimal, further dispelling these theories.
The Real Culprit: Hitter Adjustments
The enigma was finally unraveled when Gilbert's foul ball rate skyrocketed from 0.448 to 0.650. This single factor explained nearly half of Gilbert's efficiency dip. Hitters fouled off more pitches, especially in plate appearances ending with contact, extending at-bats and increasing pitch count.
The Impact: A Strategic Shift?
The rise in foul balls coincided with a strategic adjustment in hitter approach. Gilbert's foul rate increased across all pitch types, suggesting opposing hitters may have changed their strategy. This adjustment led to longer plate appearances, impacting Gilbert's overall efficiency.
The Future: Adapting to Change
Gilbert's strikeout gains and improved command metrics offer a silver lining. However, the challenge lies in maintaining these gains while addressing the foul ball issue. The lack of a clear explanation for hitter adjustments leaves a question mark over Gilbert's future performance.
The Price of Greatness: Embracing the New Normal
Gilbert's 2025 season presented a unique blend of success and efficiency challenges. While the reasons behind the efficiency dip remain unclear, the focus shifts to adapting and finding a new balance for the 2026 season.
