Sam Jethroe’s Negro League career began in 1938. Once he became an everyday player he quickly became one of the league’s top performers. Over eight seasons, Jethroe made the All-Star team four times, showcasing his consistent performance.

He played on two pennant-winning clubs, in 1945 and 1947. His ’45 team won the Negro League World Series.

According to BaseballReference.com, Jethroe’s Negro League career spanned exactly 162 games, the same number of regular-season contests in today’s Major League Baseball. This makes Jethroe’s Negro League production easy to decode.

In those 162 games, Jethroe batted .318, with 38 stolen bases, 138 runs scored and 198 hits. He recorded 48 doubles, 16 triples, and 9 home runs, with 92 runs batted in. His on-base percentage was .368, and his slugging percentage stood at .483. These numbers reflect Jethroe’s ability to impact a game, with contact, speed, and extra-base power.

Shown here is a personal check signed by Chet Brewer, a teammate in Jethroe’s final three Negro League seasons with the Cleveland Buckeyes. Brewer was an outstanding pitcher who was named to the Veterans Committee final ballot in 2006. That year 17 of the 39 on the final ballot were elected in what remains the largest Cooperstown class.

On July 11, 1948, the Brooklyn Dodgers signed Cleveland Buckeye centerfielder Sam Jethroe. The fleet-footed flycatcher spent the rest of ’48 and all of the ’49 season with the Dodgers Triple-A affiliate in Montreal.

Then on October 4, 1949, Dodgers team president Branch Rickey traded Jethroe to the Braves in a five-player deal. Six months later Jethroe integrated the Boston franchise as the team’s Opening Day centerfielder.

In the collection is this letter dated May 22, 1947 – one month after Jackie Robinson’s historic color-line -breaking April 18th debut. The correspondence is signed by Hall of Fame executive Branch Rickey who signed Robinson and Jethroe. Rickey thanks fellow Dodger owner Walter O’Malley for a television set.
