EDGE Analysis

Manager Tony La Russa didn't sound too concerned about the severity of Moncada's injury but said that the team wanted to give the third baseman an extra day of rest prior to Friday's scheduled day off. Moncada should be considered day-to-day ahead of Saturday's series opener against the Cubs.
