NEW YORK — Cam Schlittler has finished a regular season that belongs in a section of Yankees history occupied by Ron Guidry, Spud Chandler, Lefty Gomez, Whitey Ford and Gerrit Cole.
The question now is where exactly his 2026 performance belongs among them.
Schlittler completed the regular season at 14-6 with a 1.95 ERA, 239 strikeouts and a 0.92 WHIP across 193 2/3 innings and 33 starts. His ERA was the Yankees’ lowest since Guidry’s 1.74 in 1978. Since ERA became an official statistic in 1913, only Chandler’s 1.64 in 1943 and Guidry’s 1.74 have been lower for a qualified Yankees pitcher.
Then there is another measure that makes Schlittler’s season even harder to dismiss.
Baseball-Reference lists his 216 ERA+ as the highest single-season mark in Yankees history, ahead of Guidry’s 208 in 1978 and Chandler’s 198 in 1943. ERA+ adjusts ERA for league scoring environment and ballpark, with 100 representing league average.
MLB Network went even further in a ranking shown this week, putting Schlittler’s 2026 season first among nine standout Yankees pitching performances.
That placement creates a fascinating historical comparison because Schlittler does not lead every category. Guidry carried a far larger workload. Chandler posted a lower ERA. Gomez accumulated more wins and innings. Cole owns a modern Cy Young season.
Yet Schlittler’s combination of run prevention, strikeouts and era-adjusted dominance puts 2026 firmly in that company.
Top single-season pitching performances by a Yankees pitcher
| Rank | Pitcher (season) | W-L | ERA | IP | K | WHIP |
| 1 | Cam Schlittler (2026) | 14-6 | 1.95 | 193 2/3 | 239 | 0.92 |
| 2 | Ron Guidry (1978) | 25-3 | 1.74 | 273 2/3 | 248 | 0.95 |
| 3 | Lefty Gomez (1934) | 26-5 | 2.33 | 281 2/3 | 158 | 1.41; 25 complete games |
| 4 | Spud Chandler (1943) | 20-4 | 1.64 | 253 | 134 | 0.99; Five shutouts |
| 5 | Gerrit Cole (2023) | 15-4 | 2.63 | 209 | 222 | 0.98 |
| 6 | Allie Reynolds (1952) | 20-8 | 2.06 | 244 1/3 | 160 | 1.19; Six shutouts |
| 7 | Whitey Ford (1958) | 14-7 | 2.01 | 219 1/3 | 145 | 1.07; Seven shutouts |
| 8 | Catfish Hunter (1975) | 23-14 | 2.58 | 328 | 177 | 1.00; 30 complete games |
| 9 | Andy Pettitte (1997) | 18-7 | 2.88 | 240 1/3 | 166 | 1.24 |
The historical lines show why comparing generations is difficult. Gomez threw nearly 282 innings in 1934. Hunter reached 328 in 1975. Guidry finished almost 80 innings above Schlittler in 1978.
Modern pitchers are not asked to absorb that type of workload.
Schlittler’s case rests elsewhere.
Schlittler has one statistical edge even Guidry cannot match
Guidry’s 1978 season remains one of the most imposing in franchise history.
The left-hander went 25-3 with a 1.74 ERA over 35 starts. He threw 16 complete games and nine shutouts while striking out 248 in 273 2/3 innings.
His .893 winning percentage remains the Yankees’ single-season record, and his nine shutouts are also a franchise record. He won the AL Cy Young Award unanimously and finished second in MVP voting.
But era-adjusted run prevention gives Schlittler a compelling argument.
Baseball-Reference credits Guidry with a 208 ERA+ in 1978. Schlittler finished 2026 at 216, placing him at the top of the franchise’s single-season ERA+ leaderboard.
That does not erase the enormous workload difference.
It does show how far Schlittler separated himself from the offensive environment around him.
Chandler still owns Yankees’ lowest ERA
Schlittler also could not catch Chandler in one of baseball’s most recognizable pitching measurements.
Chandler went 20-4 with a 1.64 ERA in 1943. He worked 253 innings, completed 20 of his 30 starts and produced a 198 ERA+.
He won the American League MVP Award that season.
Chandler’s 1.64 remains the lowest qualified ERA by a right-handed Yankees pitcher. Guidry owns the left-handed record at 1.74.
Schlittler therefore finishes behind both in raw ERA but ahead of both in ERA+.
That distinction is at the heart of any attempt to place his season historically.
Lefty Gomez built case through dominance and volume
Lefty Gomez’s 1934 season looks almost foreign by modern workload standards.
He went 26-5 with a 2.33 ERA while throwing 281 2/3 innings. He completed 25 of 33 starts, tossed six shutouts and finished with 8.4 Baseball-Reference WAR.
His 176 ERA+ indicates the 2.33 mark was significantly better than the league environment surrounding him.
His 26 victories also remain the Yankees’ single-season record for a left-hander.
Schlittler threw 88 fewer innings.
He also struck out 81 more batters.
The contrast underscores how radically pitching has changed.
Schlittler moves beyond Cole’s Cy Young benchmark
For modern Yankees fans, Cole’s 2023 season provides the cleanest comparison.
Cole went 15-4 with a 2.63 ERA, 222 strikeouts and a 0.98 WHIP over 209 innings. He led the American League in ERA and won the Cy Young Award unanimously.
Schlittler finished 2026 with a lower ERA, lower WHIP and 17 more strikeouts despite pitching 15 1/3 fewer innings.
His strikeout rate also reached another historical level.
Schlittler’s 239 strikeouts tied Jack Chesbro’s 1904 total for fourth-most in a Yankees season. Only Cole’s 257 in 2022 and 243 in 2021, along with Guidry’s 248 in 1978, rank higher.
That gives Schlittler something many of the franchise’s great run-prevention seasons did not have: elite modern strikeout volume.
Reynolds, Ford, Hunter and Pettitte show depth of Yankees standard
Reynolds went 20-8 with a 2.06 ERA over 244 1/3 innings in 1952. He completed 24 games, threw six shutouts and even recorded six saves while finishing second in MVP voting. (Baseball-Reference)
Ford posted a 2.01 ERA over 219 1/3 innings in 1958. He threw 15 complete games and seven shutouts and finished with a 177 ERA+.
Hunter’s 1975 workload may be the most jarring number on the list. He threw 328 innings, completed 30 games and went 23-14 with a 2.58 ERA. His 8.1 Baseball-Reference WAR reflects both quality and extraordinary volume.
Andy Pettitte’s 1997 season adds another modern benchmark. He went 18-7 with a 2.88 ERA and worked 240 1/3 innings, finishing with 8.4 Baseball-Reference WAR. (Baseball-Reference)
Those seasons did not look alike.
Neither does Schlittler’s.
So where does Schlittler’s 2026 season stand?
Statistically, his place near the very top is difficult to dispute.
His 1.95 ERA ranks behind only Chandler and Guidry among qualified Yankees seasons since 1913. His 216 ERA+ leads the franchise’s single-season leaderboard. His 239 strikeouts are tied for fourth-most in club history, and no Yankees pitcher since Guidry had finished a season with an ERA below 2.00.
Where the older seasons maintain an overwhelming advantage is workload.
Guidry threw 273 2/3 innings. Gomez threw 281 2/3. Hunter threw 328. Schlittler stopped at 193 2/3.
That makes a direct one-number comparison impossible.
But 2026 no longer needs to be described merely as an excellent season or even an elite modern Yankees season.
By raw ERA, adjusted ERA and strikeout production, Schlittler has forced his way into the franchise’s most exclusive pitching conversation.
And at age 25, his final regular-season line now sits beside seasons that Yankees fans have been measuring pitchers against for generations.
