Flores is out of the lineup for Monday's game against the Padres, Jeff Sanders of The San Diego Union-Tribune reports.
Flores started twice at third base and once at designated hitter through the first three games of the season, and he'll be the odd man out Monday. He's 1-for-10 with a double, an RBI and a walk and should continue to have a regular role in the lineup with Tommy La Stella (Achilles) and Evan Longoria (finger) on the injured list.
