The Best Pitcher in Baseball 60 Years Ago Would Be Fighting for a Spot in Double-A Today

In 1965, Sandy Koufax was arguably the most unhittable pitcher alive. He struck out 382 batters that season, threw a perfect game, and won the Cy Young Award for the third time in four years. He was supernatural. Fans and writers ran out of words for him.

He was also, by the standards of today's game, throwing at a velocity that the average Triple-A reliever now surpasses on a bad day.

That's not a knock on Koufax. It's a window into something genuinely astonishing: the relentless, compounding upward march of athletic performance, and how completely it has redrawn the line between good enough and elite.

The Numbers Don't Lie — They Just Surprise You

Let's start with the most obvious metric: fastball velocity.

In the early-to-mid 1960s, a pitcher throwing 90 miles per hour was considered hard-throwing. The average fastball across the league sat somewhere in the low-to-mid 80s. Koufax, at his peak, was likely in the low 90s — which, for the era, was exceptional.

Today? The MLB average fastball velocity sits above 94 mph. Relievers routinely hit 97, 98, 99. Triple digits, once the exclusive territory of legends, is now almost expected from high-leverage bullpen arms. In 2023, the league saw more pitches thrown at 100 mph or above than at any point in recorded history.

Position players tell a similarly startling story. Sprint speed, now tracked obsessively via Statcast, shows that today's average MLB outfielder runs the bases at a pace that would have stood out as elite athleticism in prior decades. Body composition across the league has shifted dramatically — leaner, more muscular, more purpose-built through structured strength and conditioning programs that simply didn't exist in any organized way before the 1980s.

The Infrastructure of Improvement

Where does the gap come from? It's not one thing. It's a stack of compounding advantages that today's players have access to from the time they're teenagers.

Nutrition science has transformed how athletes fuel and recover. Players in the 1960s largely ate what everyone else ate — processed food, limited protein awareness, and no real concept of recovery nutrition. Today's MLB players work with team dietitians, follow individualized macronutrient plans, and treat food as a performance variable as seriously as any drill.

Strength and conditioning as a formal discipline barely existed in professional baseball until the 1980s. Before that, players were often actively discouraged from lifting weights — the conventional wisdom held that it would make them stiff and ruin their swing. Today, every MLB organization has a full strength staff, and players arrive in spring training looking like they've been sculpted for the role.

Data analytics has changed not just how teams evaluate players but how players train. Pitch design is now a legitimate specialty — pitchers work with coaches to engineer movement profiles for their breaking balls using high-speed cameras and spin-rate data. A curveball in 1965 was thrown on instinct and feel. A curveball in 2024 is often the product of months of deliberate biomechanical refinement.

Sports medicine has extended careers and accelerated recovery from injuries that once ended them. Tommy John surgery, now almost routine, was experimental when it was first performed — on actual pitcher Tommy John — in 1974. The ability to repair, rebuild, and return players to high performance has kept elite athletes competitive into their mid-to-late thirties in ways that were rare in earlier eras.

What This Means for the Legends

Here's where it gets philosophically tricky, and worth thinking about carefully.

Does the fact that Koufax's velocity would be unremarkable today make him less of an athlete? Of course not. He was operating at the absolute ceiling of what was physically achievable given the knowledge, tools, and training methods of his time. That's what excellence always means — pushing the boundary of the possible in the era you inhabit.

But it does mean that the boundary itself keeps moving. The ceiling keeps rising. And the athletes who would have been considered freaks of nature in 1965 — the ones with the unnatural arm speed, the impossible reflexes — are, in 2024, the baseline for what you need just to get drafted.

The average MLB player today is bigger, faster, stronger, and more analytically prepared than at any previous point in the sport's history. Minor league players who never reach the majors would, in many cases, have been legitimate big leaguers in a prior generation.

The Gap Keeps Widening

There's no finish line here. The tools keep improving — wearable biometrics, AI-assisted swing analysis, genetic performance research. The next generation of players will likely make today's athletes look the way today's athletes make the 1965 All-Stars look.

That's not a sad story. It's an extraordinary one. It's the story of what happens when human beings decide to take something seriously and throw every available resource at optimizing it.

Sandy Koufax was a marvel. He just happened to be a marvel in an era that hadn't yet figured out how high the ceiling could go.
