It's fitting that the Rangers are the opponent since Blyleven did pitch for Texas in 1976-77. He was traded to the Rangers in May 1976 and he ended up going 23-23 with a 2.74 ERA in Texas. That mark included a no-hitter against the California Angels on Sept. 22, 1977. It was the second no-hitter in franchise history at the time.
The Twins do like to hold these ceremonies with the Rangers in town. Last season, the Twins held a big 50-year celebration weekend during a Rangers series. Manager Ron Washington even played in a Legends game at Target Field and pulled a hamstring (he also had two singles).
Anyway, it should be a nice day and it's fitting the Rangers are going to be there.
