Harold Bruce Ellingsen is an American former professional baseball player. In Major League Baseball, the left-handed pitcher worked in 16 games, including two starting assignments for the 1974 Cleveland Indians. Originally drafted by the Los Angeles Dodgers in 1967, Ellingsen stood 6 feet tall and weighed 180 pounds. Ellingsen spent six full seasons in the Dodgers' farm system before he was acquired by the Indians on April 3, 1974, in an ultimately one-sided transaction. For Ellingsen, the Indians gave up Pedro Guerrero, then a 17-year-old with one year of professional experience with the Rookie-classification Gulf Coast Indians. Guerrero would go on to play eleven seasons for the Dodgers, slug 215 home runs, bat an even .300, and be selected to five National League All-Star teams. Ellingsen began the 1974 season with the Triple-A Oklahoma City 89ers, but was recalled in July. His final two appearances in September were as a starting pitcher against the New York Yankees. In the first, on September 22 at Shea Stadium, he went seven innings and surrendered only six hits, but lost a pitchers' duel to the Yankees' Pat Dobson 2?1 when he gave up a sixth-inning home run to Bobby Murcer.
