Wendelstedt called balls and strikes in five no-hitters, tying an NL record held by Bill Klem.

On May 31, 1968, Wendelstedt made a call that preserved Los Angeles Dodgers pitcher Don Drysdale's consecutive shutouts and scoreless innings streaks.

San Francisco Giants catcher Dick Dietz came to the plate in the top of the 9th inning with the bases loaded and no outs.

Drysdale retired Dietz on a short fly ball and got out of the inning without yielding a run, earning his fifth straight shutout.

[1] On October 8, 1988, in Game 3 of the 1988 National League Championship Series, Wendelstedt, the crew chief, ejected Los Angeles Dodgers pitcher Jay Howell from the game for having pine tar on his glove after New York Mets manager Davey Johnson asked the umpires to check Howell.
