Jeff Francis 20-Win Season

Lore & Background

The 2007 Rockies rotation was a collective force, but Jeff Francis anchored it with a consistency that bordered on the mechanical. He did not overpower the altitude; he out-thought it. His 20-win season was not a single heroic performance but 30-plus starts of steady, grinding execution, each one a small victory against the physics of Denver. Rockies fans of that era speak of Francis with a particular fondness. He was not the flashiest name on the roster, not the one who drew the biggest contract or made the highlight reel on a weekly basis. But in the dugout, in the bullpen, in the quiet moments between innings when the crowd noise swelled and the thin air made every pitch feel heavier, he was the guy you wanted on the mound. His 20-win season gave the 2007 team a narrative spine: the rotation was not just good, it was historic. The rarity of a 20-win season at Coors Field cannot be overstated. The altitude reduces air density, which decreases drag on the ball and spin on the pitch. A 95-mph fastball in Denver hits the plate roughly 10 mph faster than the same pitch in a sea-level park. That single physical fact makes every strikeout, every ground ball, every clean inning a small defiance of the environment. Francis's 20 wins are, in that light, not just a stat line but a statement about what a pitcher can do when the mountain is working against him.

In Their Own Story

The stadium lights hummed against the dark Colorado sky, and the air tasted like cold iron. Francis stood in the mound circle, glove low, and felt the familiar thinness of it—the way the ball left his hand a half-beat too fast, the way the changeup still seemed to float when it should sink. He'd been thinking about it all week: 19 wins, one more. The Rockies bench was quiet, eyes on him. He set his feet, felt the dirt shift under his cleats, and delivered. The slider broke just enough. The batter swung through. The umpire's call was a whisper in the noise. Twenty. He didn't celebrate. He just walked back to the dugout, nodded to the catcher, and let the crowd's roar wash over him like wind off the Flatirons.

Reader's Guide

Jeff Francis's 20-win season in 2007 is often cited as one of the most difficult pitching achievements in Rockies history, and the reason is geological as much as athletic. Coors Field sits at roughly 5,280 feet of elevation, where air density is lower than at sea level. This has two compounding effects on pitching: the ball experiences less aerodynamic drag, so it arrives at the plate faster and carries farther, and spin rates on breaking balls are reduced, making them less effective. Home run rates at Coors Field have historically been among the highest in baseball, which means a starter must navigate a higher volume of hard contact to get through a game. Accumulating 20 wins requires not just excellence but sustained durability across a full season in those conditions. This is why Francis's 20–5 record is held in such high regard by Rockies fans. It was not a fluke of a short stretch or a weak schedule. It was 30-plus starts, each one a negotiation with thin air, and the cumulative result was a season that will likely remain one of the franchise's most durable pitching benchmarks for years to come.
