David Dale Alexander (April 26, 1903 – March 2, 1979), nicknamed "Moose",[1] was an American baseball player and manager.

In May 1933, Alexander sustained third degree burns on his leg and later developed gangrene after being given diathermy treatment for a twisted knee.

He also served as a minor league manager for the Sanford Lookouts (1939), Thomasville Tourists (1940), Selma Cloverleafs (1941), Greeneville Burley Cubs (1942), Knoxville Smokies (1946–1948), and Jacksonville Tars (1950).

[2] Alexander began playing professional baseball for his hometown team, the Greeneville Burley Cubs of the Appalachian League, in 1923 and 1924.

[6] On December 5, 1928, the Detroit Tigers purchased Alexander and pitcher Augie Prudhomme from Toronto for $100,000 cash and three players to be named later.

[1][15] On June 13, 1932, the Tigers traded Alexander with Roy Johnson to the Boston Red Sox, in exchange for Earl Webb, who had set a major league record with 67 doubles in 1931.

He was given diathermy treatment ("electrically induced heat" used for muscle relaxation) in the clubhouse by Red Sox trainer Doc Woods.

"[20][22] Alexander attempted a comeback but injured his leg again in July 1933 and saw limited action for the rest of the season, mostly as a pinch hitter.

[1] After 1933, Alexander's mobility and fielding suffered, but he was able to hit well enough to continue playing in the minor leagues, primarily as a first baseman, until 1942.

Alexander's return to the minor leagues began in February 1934 when the Red Sox assigned him to the Jersey City Skeeters.

[24] During the 1934 season, he appeared in 134 games for Newark, principally as a first baseman, and hit .336 with 123 RBIs, 14 home runs, 35 doubles, and seven stolen bases.

He compiled a .358 batting average in 1935 and set a new American Association record by hitting four home runs in a game against Minneapolis on June 14, 1935.

[4] During his minor league playing career, Alexander never hit under .300 until 1942, his final year as a professional baseball player.

[4] While serving as manager of the Greeneville club, he also ran an unsuccessful campaign to be elected as the sheriff of Greene County, Tennessee.

[35] After resigning from Knoxville and continuing through the 1949 season, Alexander served as a scout for the New York Giants covering the states of Kentucky and Tennessee.

[37] In June 1950, Alexander was hired to take over mid-season as the manager of the last-place Jacksonville Tars in the South Atlantic League.

He has also been credited with spotting Willie McCovey who grew up in Mobile, Alabama, and began playing in the Georgia State League.

[2] In November 1962, he was hired as a scout for the Milwaukee Braves with responsibility for Tennessee, northern Alabama, and southwestern Virginia.
