MLB analyst Mike Petriello posted something on September 7 that looked like a typo — but wasn’t. In the 2026 season alone, Pete Crow-Armstrong has already faced 28 teams, 286 pitchers, and played in 22 different stadiums. Joe DiMaggio, across his entire 13-season career with the New York Yankees (1936–1951), faced 7 teams, 321 pitchers, and played in 9 stadiums. Petriello’s conclusion was short and devastating: «It’s a different sport.»
The numbers don’t lie — but they don’t explain themselves either
The American League DiMaggio played in had 8 franchises. Eight. Every opponent fit on one bus, and ace starters routinely finished what they started — which is actually why DiMaggio’s pitcher count (321) is higher than PCA’s so far. But that measures something completely different across eras. DiMaggio saw 321 pitchers over 13 years because starters went nine innings. Crow-Armstrong has seen 286 in a single season because today’s manager might deploy four, five, or six specialized relievers on a random Tuesday in August.
The 2026 MLB has 30 teams. Road trips stretch from Miami to Seattle, from Toronto to San Diego. A Cubs center fielder crosses time zones and digs in against a 23-year-old lefty who was in an independent league three years ago, throwing a sweeper no classic scout ever filmed. It’s not better or worse than DiMaggio’s game — it’s structurally unrecognizable compared to it.
PCA isn’t just logging miles — he’s making history
Petriello’s comparison lands at the perfect moment to appreciate what Crow-Armstrong is actually doing in 2026. On September 6, he hit his 40th home run against the Miami Marlins, becoming the 10th player in Cubs history to reach that mark in a single season and the first left-handed hitter to do it since Billy Williams hit 42 in 1970. By the time this piece published, he was already at 41 home runs, 97 RBI, and a .953 OPS in 145 games.
That’s not just a franchise story. PCA leads all of MLB in fWAR at 9.2 — meaning the Cubs win roughly 10 more games per season with him than they would with a replacement-level player. He also leads the National League in slugging (.569) and OPS (.943). In August alone, he was named NL Player of the Month after hitting .280 with a 1.069 OPS and 14 home runs in a single calendar month.
He’s 24 years old and under contract through 2032. The modern game — the one DiMaggio wouldn’t recognize — seems built exactly for what he does.
What does this say about the era debate?
Petriello’s comparison isn’t a shot at DiMaggio, whose .325 career batting average and 1955 Hall of Fame induction speak for themselves. It’s a reality check on how we evaluate players across generations. When someone says hitting was harder back then, or that today’s numbers don’t count the same way, this data holds up a mirror: harder for whom? Under what structure?
A hitter in the 1940s faced the same 8 opponents over and over, with the same starters he’d memorized. Today, Crow-Armstrong steps in against pitchers he’s never seen, throwing pitches that didn’t exist as a concept a decade ago. Statcast clocks him with a 90.5 mph average exit velocity and a 49% Hard Hit rate — and still, the game he’s navigating is one DiMaggio literally would not have recognized.
Petriello’s tweet doesn’t close the era debate. It opens it with data. And in baseball, that’s the most honest thing you can do.
