What Al Simmons's 1930 Season Would Look Like in 1927
This page projects Al Simmons's production from the 1930 run environment into the 1927 one, so the two can be compared directly. His actual line was .381/.423/.708, 1.130 OPS. Translated to 1927 conditions, that becomes .366/.411/.646, 1.057 OPS. The translation rescales counting stats by the ratio of league run scoring between the two eras; it does not attempt to model park, travel or integration effects.
- AVG (Batting Average):
- Hits divided by at bats. .300 is the traditional mark of an excellent hitter.
- OBP (On-Base Percentage):
- How often a batter reaches base: (H + BB + HBP) divided by (AB + BB + HBP + SF).
- SLG (Slugging Percentage):
- Total bases divided by at bats — a measure of power rather than frequency.
- OPS (On-Base Plus Slugging):
- On-base percentage plus slugging percentage, the quickest single summary of offensive value. .900 or better is star-level.

What would Al Simmons's 1930 season look like if he hit in 1927 instead? Below, his real 1930 line sits beside a cross-era translation into 1927's run environment — and a live slider lets you drop that season into any year in MLB history.
Al Simmons — 1930 (real)
Translated to 1927
Why the translated line is lower: 1927 was a tougher, lower-offense run environment than 1930 (league OPS .784 → .737).
What this translation does not account for
This is a model, not a prediction. It re-expresses only Al Simmons's rate stats against 1927's league run environment — and nothing else. It does not account for the depth of competition (integration, international talent, a vastly larger athlete pool), pitch velocity, modern pitch arsenals (sliders, splitters, sweepers), strength and conditioning, or in-game adjustments and advanced scouting.
So a higher translated line means 1927 was simply a higher-offense era — not a claim that Al Simmons would actually perform better against today's pitching.
Rate Stats: Real vs. Translated
These rate stats are re-expressed by holding Al Simmons's performance relative to his league constant and re-basing it on 1927's averages (the same idea behind OPS+/ERA+).
| Stat | 1930 (real) | 1927 (modeled) |
|---|---|---|
| AVG | .381 | .366 |
| OBP | .423 | .411 |
| SLG | .708 | .646 |
| OPS | 1.130 | 1.057 |
Counting Stats (1930, as played)
| Games | 138 |
| At-Bats | 554 |
| Hits | 211 |
| Home Runs | 36 |
| RBI | 165 |
| Runs | 152 |
| Walks | 39 |
| Stolen Bases | 9 |
Why counting totals aren't translated: scaling a counting stat by the league environment ratio massively over-inflates era outliers — e.g. a 1920s slugger's home runs would balloon to absurd modern totals. So home runs, RBI, wins, strikeouts and the like are shown exactly as Al Simmons produced them.
Verdict
This is a model, not a prediction. In 1927, Murderers' Row and the first great live-ball offense — a run environment tougher for hitters than 1930's (league OPS .784 → .737) — one reasoned way to express Al Simmons's 1930 season is roughly .366/.411/.646 with a 1.057 OPS. That figure holds his performance relative to his league constant and re-bases it on 1927's averages; it is not a claim that Al Simmons would actually post that line. His counting totals (36 HR, 165 RBI) are shown exactly as he played them, because scaling counting stats across eras wildly inflates outliers.
