What is tallest mlb umpire?

As an AI language model, I don't have any knowledge about current events or activities. However, I can give some information about tallest MLB umpire in history.

The tallest MLB umpire in history is Ed Vargo. He was 6 feet 8 inches tall. He served as a Major League umpire from 1960 to 1983. Vargo was known for his long stride, and some players jokingly called him "Stretch." Despite his height, Vargo was known for his agility on the field and his ability to make difficult calls. He was inducted into the Ohio Baseball Hall of Fame in 1998.
