In 1976, the California Angels drafted Larry in the 18th round of the June draft, but he did not sign with the team. Instead, he opted to continue his career at Bowling Green. The next year, after his senior season, he was drafted by the Atlanta Braves in the 17th round of the June draft and signed with them. Atlanta assigned him to the Greenville Braves of the single A Western Carolina League. In his rookie season of pro ball, Owen batted.282 and drove in 24 runs. The next season, he was promoted to double A, playing for the Savannah Braves. Though his batting average dipped facing tougher competition, Owen hit 11 home runs and drove in 45 runs. Despite his poor average, Owen earned a call up to the Triple ARichmond Braves. He only appeared in a handful of games with Richmond, but still managed to get ten hits and drive in three runs. In 1979, he played the entire season at Richmond, but his batting average did not improve, and in 1980, he found himself back in Double-A ball. Though Owen had home run ability, he struggled to keep his batting aver above the Mendoza Line and he struggled with strike outs. On August 14, 1981, Larry Owen made his MLB debut, against the Los Angeles Dodgers. He was a late defensive replacement for Bruce Benedict and went hits. Owen's ineptness at the plate didn't matter though. The Dodgers won 5-0 behind the pitching of Dave Goltz. Over the course of the next several season, Owen, once consider a top prospect, would spend his time going bouncing from the minor leagues to the majors, never staying for longer than a handful of games. In 1986, he left the Braves as a free agent. The following spring, he signed with the Kansas City Royals as a free agent, appearing mostly as a back-up to Jamie Quirk and Ed Hearn, the latter who'd been acquired from the New York Mets. The 1987 season was a tough one for the Royals. Dick Howser, who just two years earlier lead them a World Series championship, died of brain cancer. Billy Gardner, the ex-twins manager brought in to replace Howser while he sought treatment, was fired mid-season and John Wathan, a star catcher for that championship team, was promoted to replace him. The next season, he'd bounce between Kansas City and their Triple-A team in Omaha. At the end of the season, the Royals released Larry Owen outright, in order to make room for top prospect Mike MacFarlane. September 25, 1988, Larry Owen played his last major game, getting a hit in one at bat versus the Chicago White Sox.
