He played for the St. Louis Cardinals of Major League Baseball (MLB), appearing in one game during the 1960 season.

[2][3] Browning's lone MLB opportunity came in relief on Sunday, June 12, against the Pittsburgh Pirates at Busch Stadium.

Starting pitcher Ron Kline had already surrendered four hits and three runs and left two men on base in only one-third of an inning when Browning came into the game.

Facing his first big-league hitter, Pirate third baseman Don Hoak, Browning gave up a three-run home run to put Pittsburgh ahead 6–0, before escaping further damage.

[2] After the 1960 season, the Cardinals sent Browning, Leon Wagner, and a player to be named later to the Toronto Maple Leafs of the International League for Al Cicotte.

[8][9] After pitching for Toronto in 1962 and starting the 1963 season with them, he was traded to the Portland Beavers of the Pacific Coast League for infielder Hap Richie in June 1963.
