Manager Ron Washington said that he wanted to give Beltre's legs some rest by keeping him off the artificial turf of Rogers Centre.
"We're trying to protect his legs," Washington said. "It will also give Michael a chance to get some games on the field and not make Beltre have to go out there and stand on the turf for a long period of time."
Washington would not say whether he will do the same for Tuesday's second game of the series.
"We'll just wait and see," Washington said. "We just have to wait until [Tuesday] when I come and make my lineup, we'll see. We'll just go day-to-day on that. But today I wanted to get him off that turf."
It was Young's fourth start of the season at third base. He also has started four games at second base. Young batted third in the lineup, the spot usually occupied by outfielder Josh Hamilton who was not in Monday's lineup because of a stiff back.
