Quick post this morning since I’m in between a few things. Today’s topic: Madison Bumgarner is very young, and good!
A couple of Baseball-Reference Play Index searches to prove my point.
Search criteria: 1950-2011, age capped at 21-years-old, at least 250 IP, 60% of games started, sorted by ERA+

And for fun, if we limited our search to lefties…

1) It’s rare for anyone to be doing anything above-average in the majors at age 21, or less, and 2) Madison, as expected, is surrounded by some well known names on these two lists — Gooden, Drysdale, Blyleven, Tanana, Eckersley, and Valenzuela. There are, however, some cautionary tales. From ages 22-27 Bill Stafford posted a 91 ERA+ while struggling with an arm injury; from ages 22-26 Britt Burns posted a 108 ERA+ while dealing with injuries; and I’d be remiss if I didn’t mention Gooden. It’s hard to compare Gooden with players that were just hurt by injuries as Gooden was part injury, part work load, and part substance abuse issues. Still, he’s a good, if not sad, example of why you can’t extrapolate careers from early success.
Pitching health usually seems like it’s predestined by the gods, so it’s hard to see how Bumgarner will ultimately turn out, but he’s really on a fantastic start to his (young) career.
