So baseball’s instant replay is a success, as opined by Thomas Boswell [“On further review, maybe this newfangled replay works after all,” Sports, June 2]. Only one imprecision remains: the calling of balls and strikes. Mr. Boswell believes technology has done a favor to umpires since it shows “how seldom they miss a pitch.” I notice how often they get it wrong. If the technology is accurate, baseball should use it.

It’s like spell check. If a writer turned it on but didn’t use it, we could see how many times she spelled words right, although I’d probably still see only the misspelled words. Still, as Meat Loaf says, “Two out of three ain’t bad.”
