winning percentage is the second-worst in the modern era and the second-worst in National League history (ahead of the 1899 Cleveland Spiders with a .130 winning percentage). Fuchs lost control of the team in August 1935, and the new owners tried to change the team's image by renaming it the Boston Bees. This did little to change the team's fortunes. After five uneven years, a new owner, construction magnate Lou Perini, changed the nickname back to the Braves. He immediately set about rebuilding the team. World War II slowed things down a little, but the team rode the pitching of Warren Spahn to impressive seasons in 1946 and 1947. In 1948, the team won the pennant, behind the pitching of Spahn and Johnny Sain, who won 39 games between them. The remainder of the rotation was so thin that in September, Boston Post writer Gerald Hern wrote this poem about the pair: First we'll use Spahn then we'll use Sain Then an off day followed by rain Back will come Spahn followed by Sain And followed we hope by two days of rain. The poem received such a wide audience that the sentiment, usually now paraphrased as "Spahn and Sain and pray for rain", entered the baseball vocabulary. However, in the 1948 season, the Braves had the same overall winning percentage as in games that Spahn and Sain started. The 1948 World Series, which the Braves lost in six games to the Indians, turned out to be the Braves' last hurrah in Boston. In 1950, Sam Jethroe became the team's first African American player, making his major league debut on April 18. Amid four mediocre seasons, attendance steadily dwindled until, on March 13, 1953, Perini, who had recently bought out his original partners, announced he was moving the team to Milwaukee, where the Braves had their top farm club, the Brewers. Milwaukee had long been a possible target for relocation. Bill Veeck had tried to return his St. Louis Browns there earlier the same year (Milwaukee was the original home of that franchise), but his proposal had been voted down by the other American League owners. Milwaukee (1953–1965) Milwaukee went wild over the Braves, drawing a then-NL record 1.8 million fans. The Braves finished 92–62 in their first season in Milwaukee. The success of the relocated team showed that baseball could succeed in new markets, and the Philadelphia Athletics, St.
