SAN DIEGO -- The Rockies placed second baseman DJ LeMahieu on the disabled list with a sprained left thumb prior to Monday's series opener against the Padres. Infielder Pat Valaika was recalled from Triple-A Albuquerque.
"We're concerned about it,'' manager Bud Black said before the roster move. "We're trying to be optimistic on this one, but we will have to wait and see.''
LeMahieu, a two-time All-Star, lands on the disabled list for the second time this season. He was activated on May 8 after being waylaid by a strained hamstring.
