Flags at the Great American Ballpark were lowered to half-staff during Saturday's game in honor of the late Neil Armstrong.
Fans learned of his passing from an announcement made during the game.
Lorraine and Pete Lewis had nothing but praise for Armstrong.
"He was such a wonderful hero of ours because of all that he has done, and the fact that he's from Ohio, you know, I mean that's neat," said Lorraine.
"I can't imagine anybody having the guts to do something like that, and he loved it. You could tell just by the way he talked about it. He was just such a wonderful guy," said Pete.
Dan Woods said he will always remember watching Armstrong take those historic first steps on the surface of the moon.
"I was 8 years old when he landed, but I remember my mom and dad sitting me down and making me watch it, and I still remember that moment."
U.S. Senator Rob Portman (R- Ohio) calls Neil Armstrong a dear friend. Portman describes the late astronaut as a "reluctant hero" who was dedicated to serving his country, first as a fighter pilot during the Korean War and later through space exploration.
Portman also said Armstrong never understood the public's fascination with him. Armstrong saw himself as a man who was just doing his job, according to Portman.
U.S. Senator Sherrod Brown (D- Ohio) also knew Armstrong.
"The last time I spoke with him, we discussed the need to instill a love for science and math in young people. Neil inspired so many Americans, and I have no doubt that his legacy will motivate more Ohioans to continue our state's proud tradition of leadership in aerospace," he said in a written statement.
