Diamondbacks place Lamb on 15-day disabled list
Lamb was off to a strong start to the season, going 12 for 29 with nine RBIs in 10 games.
Arizona called up infielder Danny Dorn from Triple-A Reno and transferred catcher Gerald Laird to the 60-day disabled list after back surgery. Dorn, 30, has yet to make his major league debut.
Laird played in one game before undergoing surgery on Monday. The Diamondbacks open a two-game series against the Texas Rangers on Tuesday.
