The
Los Angeles Dodgers selected Yeager in the fourth round of the
1967 Major League Baseball draft. After one game with the
rookie level
Ogden Spikers of the
Pioneer League, Yeager was sent to the Dodgers'
Single-A affiliate, the
Dubuque Packers of the
Midwest League. The following season, in 1968, Yeager played 59 games for the Single-A
Daytona Beach Dodgers of the
Florida State League. In 1969, he played 22 games for the
Bakersfield Dodgers, the Dodgers' Single-A affiliate in the
California League, where he threw out 26 runners from behind the plate. That season he suffered a fractured leg in a first-inning collision with a runner at home plate, but was not aware how bad his injury was, and finished the game. Yeager was promoted to
Double-A before the end of the 1969 season, playing in one game for the
Albuquerque Dodgers of the
Texas League. He spent the next two-and-2/3 seasons with the Double-A franchise. In 162 games played over the 1970 and 1971 seasons, he hit .276, with 77
RBIs in 490 at bats. He threw out 84 runners, second in the league that year, and was named to the Texas League
All-Star team as a catcher in 1971. In
spring training in 1972 he won the Dodgers writers' Dearie Mulvey Memorial Trophy as the best rookie. With the Dukes becoming the new
Pacific Coast League Triple-A affiliate for the Dodgers in 1972, Yeager was promoted while remaining in
Albuquerque for another season. “You won't beat that arm of his,”
Tommy Lasorda said that season. With the Triple-A Dukes, he played 82 games, batting .280 with 45 RBIs and a slugging percentage of .502, in 257 at bats. ==Major league career==
