Daniel Ray "Danny" Herrera (born October 21, 1984 in Odessa, Texas) is an American professional baseball pitcher for the New York Mets of Major League Baseball. Herrera has become well known among baseball fans both for his short stature, and for his unique pitch repertoire. Currently, Herrera is not only one of the shortest pitchers in recent history at 5' 6", but is also one of the few active pitchers in Major League Baseball to throw a true screwball.
