[4] In October, he was drafted into the Army, serving the remainder of the year, as well as 1945 and 1946, with the 94th Infantry Division and winning the European Armed Forces batting championship with a .343 average.

He combined his earlier speed (his 100-yard dash in uniform had been clocked at 10 seconds[3]) with newfound power, hitting 19 home runs, 19 doubles, and a team-leading 20 triples.

[6] The following day, he helped pitcher Curt Simmons, a former teammate in American Legion Baseball,[2] earn his first victory over Andy Hansen of the Giants by hitting safely twice in four times at bat and scoring one run.

[7] After offseason medical treatment at Johns Hopkins University, Levan opened the 1948 season with the Toronto Maple Leafs of the International League.

[2] He batted .291 in 223 at-bats with the class-A Sunbury Reds, amassing twelve doubles, three triples, and five home runs,[11] but by the end of the year had been demoted to the class-D Bluefield Blue-Grays.

[16] In 1953, he played a short period with the Atlanta Crackers,[17] but spent most of the season back in the Florida International League, batting .323 for the Fort Lauderdale Lions.

[19] Despite leading the team in these categories by season's end, Levan actually left the Miami franchise in August to report to the Single-A level affiliate of the Washington Senators, based in Charlotte, North Carolina.

[20] The Senators called him up for seven games in September; he made his American League debut on the sixth of that month, collecting no hits in four at-bats as Washington's first baseman.

[26] After hitless performances against the Detroit Tigers and the Chicago White Sox,[24] manager Chuck Dressen demoted Levan to Charlotte, ending his brief major league career.

[29] Levan was leading the 1959 Lookouts with a .337 batting average in July 1959[30] when his teammates were summoned to a meeting with the Southern Association president, Charles Hurth.

[2] The Southern Association alleged that Levan, in combination with Waldo Gonzalez, conspired to fix games by tipping pitches to opposing players.

Gonzalez was accused of relaying pitches to players and coaches for the Mobile Bears,[2] and Levan was allegedly the arranger of the scheme, "acting as a liaison agent for betting interests and offering fellow club members money to throw games".

[33] After interrogating both Gonzalez and Levan, the players were suspended indefinitely (Gonzalez' ban was later reduced to a one-year suspension) for "failure to report a bribery attempt by a gambler";[2] Levan was also placed on the permanently ineligible list, barring him from participating in any baseball events sponsored by the National Association, minor league baseball's governing body.
