A natural athlete at 6’3″, Claude Passeau earned 12 varsity letters in football, basketball, baseball, and track in field at Millsaps State in Mississippi.
After college he threw his first professional pitch in the low minors at age 23. Unpolished because of his lack of pitching experience, Passeau nonetheless showed raw talent.
He climbed his way up through the Pittsburgh system for four years from 1932-1935. After pitching one game for the Pirates in late ’35, Passeau was dealt to the Phillies. The following year he was in the big leagues to stay in ’36 at age 27.
He quickly made up for lost time.
In 1937 only three National League pitchers threw more complete games than Passeau. It was the first of nine consecutive campaigns that he finished in the top-ten of his league in the category.
On May 29, 1939 the Phillies dealt Passeau to the Cubs in the midst of his age-30 season. He soon found stardom in Chicago.
Splitting time between Philadelphia and the Windy City, Passeau led the NL in strikeouts. It was the third of his 8 seasons in the NL’s top ten.
The following year in 1940 Passeau’s 7.6 WAR was the highest of any position player or pitcher on the Senior Circuit. A 20-game winner for the first time, Passeau placed second in ERA and led the league in fielding-independent pitching (FIP). He also gave up the least homers per nine innings.
From 1940-1945 Passeau tallied exactly 100 victories while posting a 2.79 earned run average. At the end of that run he helped the Cubs reach the World Series.
In his first postseason start Passeau pitched a gem. His one-hitter in Game 3 tied Ed Reulbach’s 1906 World Series record for least hits allowed in a complete-game effort. Today only Don Larsen’s 1956 perfect game eclipses the performance.
Passeau made his final All Star appearance as the NL’s starting pitcher in the 1946 contest. With two out in the first inning he issued a base on balls to Ted Williams. New York’s Charlie Keller followed with a two-run homer to tag Passeau with the loss.
The following year was Passeau’s last as a big leaguer.
During his 13-year big league career, Passeau made four All Star teams and received support in MVP balloting three times. He finished with 162 wins, 188 complete games, 26 shutouts, and more than 1,000 strikeouts. Passeau’s career WAR stands at 45.2, higher than 22 Hall of Fame pitchers including Herb Pennock, Dizzy Dean, Jack Morris, and Catfish Hunter.
