Originally drafted as a pitcher by the Mets in 1967, he did not begin his professional career until 1968 due to a shoulder injury. He was converted into an outfielder, and he started 1968 with the rookie class Marion Mets. After missing the 1969 and 1970 seasons while serving in the Vietnam War, Schneck continued to progress through the minor leagues until 1972, when he made his major league debut.
After spending most of 1973 back in the minor leagues with the Tidewater Tides, Schneck got his longest shot at the majors in 1974. He played 93 games with the Mets that season, batting .205 with 5 home runs. However, that proved to be the end of his major league career.
Schneck went 2–11 at the plate on September 11, 1974 during a 25 inning marathon night game against the St. Louis Cardinals. Those 11 at-bats tied a major league record for most AB in an extra-inning game.
On December 3, 1974, Schneck was traded by the Mets with Don Hahn and Tug McGraw to the Philadelphia Phillies for Del Unser, John Stearns, and Mac Scarce. He started the 1975 season with their top farm club, the Toledo Mud Hens, and on August 5 he was traded to the Cincinnati Reds for John Vukovich. He played with their top farm team, the Indianapolis Indians, until the end of the 1976 season. During that offseason, he was traded again, this time to the Chicago Cubs, for outfielder Champ Summers. After playing one more season in the minors, for the Wichita Aeros, Schneck retired.
