Andre Ethier was at Dodger Stadium and in good spirits Thursday. If he could be happy, maybe the rest of the downtrodden Dodgers had a reason to smile, too.

Ethier, who strained his left oblique muscle Wednesday in San Francisco, will avoid the disabled list for now. The team leader in RBIs, games played and doubles is listed as day-to-day.

"Day-to-day can't mean 10 days," Dodgers manager Don Mattingly said. "If it got to that, I'm sure we'd talk something different."

The right fielder was optimistic that he wouldn't go on the disabled list and could return before the All-Star break, which is 10 days away. That would be an ideal timetable for an injury that often requires four weeks of recovery time.

"I wasn't surprised. I was optimistic the whole time," Ethier said. "I've been on the DL the last couple years. I want to have a full healthy season. Sometimes that's wishful thinking."

Ethier suffered the strain in the first inning of the Dodgers' 3-0 loss to the Giants, their third shutout in as many days in San Francisco. He received an MRI exam and will not have a PRP (platelet-rich plasma) injection, which is sometimes used to stimulate tissue recovery following injuries.

Ethier described his oblique as feeling "sore" and "tender." He has never been sidelined by a similar injury in the past.
