The Diamondbacks placed Lawlar on the 10-day injured list Saturday with a right hamstring strain.
Lawlar had to come out of Friday's game after legging out an infield single, and he was later diagnosed with a hamstring strain. He'll now spend at least the next 10 days on the shelf, leaving Jorge Barrosa as the favorite to take over as Arizona's primary center fielder. Tim Tawa was recalled from Triple-A Reno in a corresponding move.
