According to the Wall Street Journal, Cleveland Indians' play-by-play man Matt Underwood and color analyst Rick Manning are the second biggest "homers" among local Major League Baseball announcers.
Underwood and Manning fell a distant second to long-time Chicago White Sox play-by-play man, Ken "Hawk" Harrelson and his partner of recent years, Steve Stone who are tops in the Majors for showing bias toward the team they cover.
The WSJ reporter Jared Diamond compiled his results after watching one home win for each of the 30 MLB teams and compiling the number of biased comments made during the broadcast to measure the level of "homerism" from the announcers. The White Sox duo led by Harrelson had 104 biased comments by game's end while the Cleveland announcers were next in line with 23 biased comments.
Manning made most of the "we" references while analyzing the Indians which makes more sense when you consider he played the first eight years of his career for the Tribe.
