A report by The Hardball Times asserts that Tschida called the smallest strike zone of all MLB umpires in 2011.

On August 3, 1987, Tschida was the plate umpire when he ejected Minnesota Twins pitcher Joe Niekro for possessing an emery board.

[3] On August 4, 1999, Anaheim Angels hitter Orlando Palmeiro struck out to lead off a game and then dropped his bat at home plate, prompting Tschida, the home-plate umpire, to eject him.

[4] Tschida made a widely disputed call in the 1999 ALCS in which Chuck Knoblauch applied a "phantom tag" to José Offerman.

[5] On June 19, 2012, Tampa Bay Rays pitcher Joel Peralta was ejected by Tschida for having pine tar inside his glove.
