Werley appeared in his only big league game on September 29, 1956, against the Washington Senators, having been signed by the Orioles just a few weeks prior on September 2.[2] He came into the game in the bottom of the eighth inning, replacing relief pitcher Bill Wight. In quick succession he retired the first two batters, Herb Plews and Ed Fitz Gerald. He then began to struggle, walking the next two batters – Pete Runnels and Roy Sievers – and allowing a single to Jim Lemon, which drove Runnels home from second. The next batter he faced was Hall of FamerHarmon Killebrew – who grounded out.[3]
Though Werley spent only one game in the major leagues, he spent three seasons in the minors, going a combined 24–22 in 88 games. In 1958 with the Dublin Orioles, he went 16–10 with a 4.28 ERA.[4]
Werley died on November 21, 2013, at age 75 in St. Louis, Missouri. He is survived by two children and eight grandchildren.
