On top of that, outfielder Carlos Gomez was placed on the DL on Sunday with a left hamstring strain, and left fielder Ryan Braun is playing through a tight right Achilles.
Oh, and the Brewers entered Sunday with a 12-15 record, four games behind first-place St. Louis in the National League Central. They ranked 15th in the NL in team ERA, a fact Attanasio expects to change over time.
"Look, plenty of other teams have injuries, too," Attanasio said. "Not necessarily season-ending injuries, but we still have an enormously talented team that we all believe is going to start playing better. I'm still at the point where I'm looking at the lineups every day before the game, and I like our lineup better than the other team's. We got off to a slow start last year, too."
Last year, the Brewers were getting healthy at this time, with right fielder Corey Hart getting back to form after a rib-cage strain and Zack Greinke returning from a cracked rib. This year is a little different.
Attanasio left open the door to some major midseason acquisitions, going as far as referencing the Brewers' July 2008 trade for starter CC Sabathia. He pointed to the Cardinals, who won the World Series last year partly on the strength of a bullpen bolstered by a big July trade.
"Everything" is on the table, Attanasio said.
"We're only  games in," he said. "It's going to depend where we're at, at that point in time. Look at where we were when we added CC. We were over .500, but we were several games back."
Brewers officials, including Attanasio, general manager Doug Melvin, manager Ron Roenicke and the club's baseball operations and coaching staffs, will meet on Tuesday at Miller Park for a previously scheduled one-month review of the team. They will discuss the short-term and long-term options for plugging the myriad of holes created on this road trip.
Complicating things for Attanasio and Melvin is the fact that three key pitchers -- Greinke, Shaun Marcum and Francisco Rodriguez -- are due to reach free agency after the season. The team's performance over the next month or two will determine whether the Brewers are in position to add talent ahead of the July 31 non-waiver Trade Deadline.
The Brewers had an 11:35 a.m. PT team meeting on Sunday to discuss a travel issue. Roenicke planned to say a few words to players about keeping their spirits up.
"There's a lot of enormously talented guys in here," Attanasio said, looking around the clubhouse.
