A "cutter" is a fastball that breaks slightly as it reaches home plate. Nasty, and hard to hit. The other cutter, of course, is a surgeon.
Today, I could not name five members of the Oakland Athletics baseball team. Nor could I name those who are assisting a cardiologist who's going to implant a pacemaker in one of my relatives.
But, once again, the Oakland A's are being used as a benchmark for the way that medicine ought to be practiced in a Wall Street Journal article focusing on developing cheaper, better care benchmarks.
