He played in Major League Baseball as a catcher and a first baseman, most prominently as a member of the Baltimore Orioles where he was a four-time All-Star player.

[2] Triandos is notable for being the first catcher in MLB history to catch a no-hitter in both the American League and the National League, catching a no-hitter by Hoyt Wilhelm in 1958 while on the Orioles in the AL and Jim Bunning's perfect game while on the Phillies in the NL.

Born in San Francisco, California, Triandos attended Mission High School and was signed by the New York Yankees as an amateur free agent in 1948.

[9] That stolen base came on September 28, 1958, in the 9th inning of the last game of the season, at Yankee Stadium, off rookie pitcher Zach Monroe and catcher Darrell Johnson.

[10] [11] Triandos had his best year in 1958, when he hit 16 home runs by mid-season to earn the starting catcher's role for the American League in the 1958 All-Star Game, breaking Yogi Berra's eight-year stranglehold on the position.

[3] With the Tigers in 1963, he shared catching duties with Bill Freehan and led American League catchers with a .996 fielding percentage.

[5][16] The following winter, he was traded along with Jim Bunning to the Philadelphia Phillies, where he again shared catching duties, this time with Clay Dalrymple.

He and wife Evelyn had three children, son Gary Triandos and daughters Lori Luna and Tracey Hook.
