Colbern was born in
Santa Monica, California. Before playing professional baseball, Colbern was an
All-American at
Arizona State University. On June 18, 1976, Arizona State, then ranked #1, faced second ranked Arizona in the college world series. Arizona State was favored to win, because the top half of their line up, one that would include Colbern and future Dodgers outfielder
Ken Landreaux was batting over .300. Behind the hitting of
Ron Hassey and pitching of
Steve Powers, Arizona pulled off the upset, 5–1. Colbern was drafted by the
Kansas City Royals in the 5th round of the 1973 MLB amateur draft out of Hawthorne High School. Colbern opted not to sign with Kansas City and instead chose to attend Arizona State. Colbern was an All-American as an outfielder. In his college career he was a career .352 hitter. In 1976, he had what might have been his best season, hitting 11 home runs while batting .361 with 78 RBIs. The
Chicago White Sox drafted Colbern in 1976 in the second round of the MLB draft. Colbern made his way through the White Sox minor league system, was batting .283 with 12 home runs and 44 runs batted in when he was called up by Chicago. He made his MLB debut on July 18, 1978, against the
Milwaukee Brewers, going 1 for 4. Perhaps one of his best games occurred on September 13, 1979, when his two-run triple helped Chicago defeat the
California Angels 11–5. He struggled, however, otherwise throughout the year and was sent down to the minors and never again played in the major leagues. On December 31, 1981, the White Sox traded Colbern to the
Atlanta Braves for journeyman minor league pitcher
Butch Edge. He played one season in the Braves minor league system, splitting his time between Triple-A Richmond and Double-A Savannah. he was released at the end of the season, ending his professional career. Though at his career in the majors, Colbern played both outfield and catcher and even a couple of games as a DH. Though Colbern's stay in the majors was short, he was in the lineup for one of the biggest fiascoes in baseball history "
Disco Demolition Night". The event involved several thousand disco records being blown up and rowdy fans storming the field. Colbern's jersey #19 currently hangs in the Elmhurst History Museum's display of the night's wild events. Colbern was part of the 1982
Richmond Braves squad that finished 82 and 57, good enough for first place in the
International League. The team was stocked with future major league talent like
Terry Harper,
Brad Komminsk,
Brook Jacoby, and
Pascual Pérez. Stuck behind veteran
Larry Owen and prospect
Matt Sinatro, Colbern only played in six games before finding himself down at double A. ==Lawsuit against Major League Baseball==
