Stuart Leonard Miller (December 26, 1927 – January 4, 2015), nicknamed The Butterfly Man,[1] was a pitcher in Major League Baseball who played for the St. Louis Cardinals (1952–56), Philadelphia Phillies (1956), New York/San Francisco Giants (1957–62), Baltimore Orioles (1963–67) and Atlanta Braves (1968).

In a 16-season career, Miller posted a 105–103 record with a 3.24 earned run average, 1164 strikeouts, and 154 saves in 704 games pitched (93 as a starter).

"[3] He was involved in one of the more memorable moments in All Star Game history, albeit for an exaggeration of the event in question.

One batter later, the wind caused catcher Smoky Burgess to drop Tony Kubek's foul pop-up for an error.

[7] Thinking he was washed up, the Giants traded him along with John Orsino and Mike McCormick to the Baltimore Orioles for Jack Fisher, Billy Hoeft and Jimmie Coker on December 15, 1962.

[11][12][13] On April 30, 1967, Steve Barber and Miller combined to pitch a no-hitter for the Orioles against the Detroit Tigers, but would lose 2–1.

Miller entered after Barber, who walked ten batters, gave up the tying run on a wild pitch with two outs.

[19] Miller's "Butterfly Man" nickname came around as a result of his ability to fool hitters with a slow curveball.
