After finishing 1962 with the Triple-ATacoma Giants, he was reacquired by Houston and assigned to the Triple-A Oklahoma City 89ers, where he had his finest minor league season in 1963, batting .363 with 86 hits in 67 games. That earned him a promotion to the Colt .45s in midseason for a 34-game stint. Weekly batted .225 with three home runs and 18 hits. His high-water mark came September 18, with three extra base hits in five at bats against the Cincinnati Reds, including two doubles off Cincinnati fireballer Jim Maloney.[4] He drove in four runs and hit his fifth and final big-league homer off the Reds' Dom Zanni.[4]
Weekly made the Houston roster coming out of spring training in 1964, but made only two hits in 15 at bats and returned to Oklahoma City. On June 15, he was traded to the Baltimore Orioles, but logged only nine games for the Orioles' Triple-A affiliate before returning to the Houston organization. After one more full year with the 89ers, in 1965, Weekly left professional baseball. He died from injuries sustained in a road accident in Walnut Creek, California on November 24, 1974.
