When Jamie Moyer pitched seven innings without allowing an earned run Tuesday night, he became the oldest winning pitcher in big-league history.

When Mr. Moyer made his big-league debut on June 16, 1986, Ronald Reagan was still president of the United States, Dick Riley was still governor of South Carolina and Joe Riley had been mayor of Charleston for a mere 10½ years.

And when a man who will turn 50 in November can still baffle major-league hitters with a 79 mph “fastball” (the highest speed he reached Tuesday night) and an assortment of even slower pitches, his enduring success demonstrates one of baseball’s enduring charms: the frequent triumph of savvy experience over youthful talent.

That familiar outcome was reprised Tuesday night at Denver’s Coors Field as Mr. Moyer led the Colorado Rockies to a 5-3 victory over the San Diego Padres. His lone strikeout in the six-hit stint came against Cameron Maybin, who wasn’t born until nearly a year after Mr. Moyer made the majors with the Chicago Cubs.

Yet youth did serve the crafty lefty’s cause in his 268th career win Tuesday night. The venerable victor hailed some crucial advice from Rockies catcher Wilin Rosario, born nearly three years after Mr. Moyer reached the bigs.

Mr. Rosario reciprocated with this apt assessment of the old-timer on the mound: “We can learn from him.”

And the rest of us can learn that at the old ballgame (or anywhere else), it doesn’t matter how old you are.

It matters how effective you are.
