The 1963 season saw more young talent mixed with seasoned veterans. Jimmy Wynn, Rusty Staub, and Joe Morgan all made their major league debuts in the 1963 season. However, Houston's position in the standings did not improve, as the Colt .45s finished in ninth place with a 66–96 record. The team was still building, trying to find that perfect mix to compete. The 1964 campaign began on a sad note, as relief pitcher Jim Umbricht died of cancer at the age of 33 on April 8, just before Opening Day. Umbricht was the only Colt .45s pitcher to post a winning record in Houston's first two seasons. He was so well liked by players and fans that the team retired his jersey number, 32, in 1965.
