At his induction into the Astros' Walk of Fame on Friday, Morgan said his greatest moment in baseball actually happened before his first Major League game with the Colt .45s in 1963. The .45s became the Astros in '65.
"The first day I put on that uniform is still the highlight of my career," Morgan said.
The Walk of Fame was unveiled this season to commemorate the 50th anniversary of the franchise. Morgan, born in Bonham, Texas, in 1943, played parts of his first nine seasons with Houston (1963-71).
He made the All-Star Game twice with the Astros, in 1966 and '70. His career blossomed after he was traded to the Reds, but he looks back on his time with the Astros fondly.
"I actually learned to play baseball right here in Houston," Morgan said.
Morgan returned to the Astros in 1980 and helped the team win the National League West.
On Friday, Morgan made sure to snap a picture of his plaque on the Texas Avenue sidewalk. Morgan also threw out the ceremonial first pitch before the game against the Indians. He said he still follows the Astros, but wishes the club wasn't moving to the American League in 2013.
"I don't like the fact that the Astros, with the 50-year history we had here, we're going to all of a sudden be in the American League," Morgan said. "I don't understand it, but then again, they didn't ask me."
He also considers the Astrodome a monument to the franchise, and said he hopes it remains intact.
"I will never forget my first few years in Houston," Morgan said.
