BraveOriole, thanks for asking.
Although he was a very weak hitter (which is probably what Over40 remembers about him) Willy Miranda did have a reputation as an excellent fielder. Because the baseball gloves of the 1950's weren't nearly as good as those of later years, his fielding percentage doesn't compare well with the likes of Mark Belanger and Ozzie Smith, but he was regarded as a top-notch fielder in his day. He was also considered to have an excellent arm.
I remember that there was a publication of some sort of other - at this late date, I don't remember whether it was a magazine or a newspaper - that ran a series of articles featuring tips from big league players. When the series started, they printed a list of all the players who would be featured in the series, and Willy was on the list.
I was thrilled. This was at a time when Baltimore generally languished in the bottom half of the American League standings and most baseball fans paid very little attention to the Orioles, so the fact that an Oriole was to be featured in this series indicated that somebody regarded him as pretty special - and not only were they going to put an Oriole in there, but it was going to be my favorite player to boot.
I eagerly awaited the tip from my hero, but when it came out, Willy talked about throwing, and emphasized the importance of getting a wrist snap into the throw.
I wanted so much to emulate my hero, but I didn't have the foggiest idea what he meant by snapping my wrist or how to do it when I threw a baseball.
Of course, given the fact that I couldn't hit, hit with power, run, or field very well, the fact that I didn't immediately pick up on the technical fine point of how to snap my wrist when I threw is probably not the only thing that kept me from being a big league shortstop. :)
