Hamilton, who leads the AL in home runs and the majors in RBI, was sidelined because of a viral infection. Young was out of the lineup for the second time in three games, this time because of a sore groin.
Young was riding a 22-game hitting streak, the longest in the majors this season. He returned to the lineup Saturday night after missing the previous game because of a hairline fracture in his left ring finger. He left after the seventh inning because of tightness in his groin. It wasn't clear when or how he hurt it.
"He made it through the finger part," Texas manager Ron Washington said. "(The groin) is not a strain. It's just sore, because he's got good flexibility."
Washington indicated that Hamilton and Young could be available to pinch hit, but nothing more. The Rangers are off Monday, which Washington said will give his regular Nos. 2 and 3 hitters extra rest.
Ramon Vazquez moved over to play shortstop for Young, and German Duran started at third base, with Marlon Byrd in center field. In the batting order, first baseman Frank Catalanotto was second and right fielder David Murphy was third.
Duran was recalled Sunday from Triple-A Oklahoma. Right-hander Elizardo Ramirez, who gave up nine runs over 2 2/3 innings in his only appearance for the Rangers, was designated for assignment.
