Jaycee Field

Jaycee Field, built in 1939 at Harmon Park in Twin Falls, was home to the minor league Twin Falls Cowboys.

Twin Falls’ Harmon Park was once home to Jaycee Field, where the Cowboys played in the Pioneer League.

The Twin Falls Junior Chamber of Commerce (Jaycees) purchased and donated 20 acres next to the original four-acre Harmon Park in 1938 and installed a baseball diamond and bleachers just in time for the 1939 season.

From 1939 through 1951 — minus the World War II years — the Twin Falls Cowboys were affiliated with the New York Yankees.

The team became the Magic Valley Cowboys in 1954 and played into the 1970s. Over the years, the new team was affiliated with the Chicago Cubs, Philadelphia Phillies, San Francisco Giants and the Atlanta Braves.

Near the end of the 1962 season, the Times-News tried to break the attendance record at Jaycee Field by offering discounted admission and free groceries to the first several thousand baseball fans through the gate to watch the Cowboys’ Labor Day doubleheader against the Pocatello Chiefs.

For 19 cents, the first 2,000 men received admission plus a one-half pound can of Butternut coffee. For the same price, the first 1,500 women received a bag of groceries — including bread from Shelby’s Market, Starkist tuna, Green Giant Niblets corn, Indian Gem applesauce, Nalley’s potato chips, Bradshaw’s spun honey, Russ-Ettes frozen french fries and Eddy’s cupcakes — worth $2.

The attendance record of 5,700 wasn’t broken that day and it may have affected the Magic Valley Cowboys’ game. Though it was the largest crowd of the season, a disappointing 3,570 fans turned out to watch the Chiefs win both games, 8-1 and 4-3 in the Times-News “Country Store Night” game.
