He batted left-handed, threw right-handed, stood 6 feet 2 inches (1.88 m) tall and weighed 195 pounds (88 kg).

Acquired by Boston from Cincinnati in a May 11, 1948, trade for fellow outfielder Danny Litwhiler, Rickert spent the following 3+1⁄2 months with the Braves' Triple-A Milwaukee Brewers farm club, batting .302 with 27 home runs and 117 runs batted in in 128 games,[2] as the MLB Braves won the National League pennant.

Needing a left-handed hitting outfielder to replace Heath, the Braves put in an urgent call to Rickert, summoned him back East, and placed him on their roster, while successfully appealing to Commissioner of Baseball Happy Chandler to make Rickert eligible for the World Series on an emergency basis.

Rickert — temporarily inheriting Heath's #4 Braves' uniform — shook off the rust by starting Boston's final three regular season games in left field (collecting three hits in 13 at bats, including a triple).

During his Major League career, Rickert collected 284 hits, including 45 doubles, nine triples, and 19 home runs.
