Mark Holtz (October 1, 1945 – September 7, 1997) was an American sportscaster, best known for his broadcasts of Major League Baseball's Texas Rangers.
Holtz and color commentator Eric Nadel, who joined him in 1982, became one of the most recognized broadcast teams in the DFW area.
In 1995, Holtz would return to TV broadcasting, where he remained until May 22, 1997, when he had to give up his duties to battle leukemia, which would claim his life on September 7 of that year.
In his memory, Mark Holtz Lake (a wide spot in Johnson Creek north of Rangers Ballpark in Arlington) is named for him.
When the Rangers beat the Tampa Bay Rays in Game 5 of the ALDS on October 12, 2010, to capture their first postseason series victory, Eric Nadel exclaimed, "Hello Win Column!"
