Thurston was born in
Fremont, Nebraska, and graduated from
John H. Francis Polytechnic High School. His nickname "Sloppy" was given to him ironically; in the often rough-and-rumble environment of early twentieth century baseball, Thurston had a reputation for being fastidiously well-groomed. Thurston was a
screwball pitcher. He played professional baseball from 1920 to 1938, spending time in the minor leagues when not in the majors. He played his first MLB game on April 19, 1923, with the
St. Louis Browns. On August 22, 1923, Thurston became the fifth pitcher in major-league history to pitch an
immaculate inning, striking out all three batters on nine total pitches in the 12th inning of a game against the
Philadelphia Athletics; he was also the first pitcher to achieve the feat in
extra innings and the only White Sox pitcher to do so for 101 years until
Michael Kopech did so in 2024. In 1924, Thurston led the American League with 28 complete games, posting a 20–14 record in 36 starts, while also leading the league in hits allowed (330), earned runs allowed (123), and home runs allowed (17) in 291 innings pitched. Thurston played his last MLB game on October 1, 1933. He finished his nine-year MLB career with a
win–loss record of 89–86, a 4.24
earned run average, and 306
strikeouts. For a pitcher, he was an excellent hitter, posting a .270
batting average (175-for-648) with 5
home runs and 79
runs batted in. Thurston's batting was good enough that he was frequently called on to pinch hit; he accumulated 53 career plate appearances as a pinch-hitter. Thurston died on September 14, 1973, in
Los Angeles, California. He is interred at
Holy Cross Cemetery in
Culver City, California. ==References==
