The five-time All-Star shortstop has missed three straight games with a strained left wrist and is listed as day-to-day.
“He’s good, but not great,” Chicago manager Dusty Baker said. “We are hoping he will be all right tomorrow with treatment.”
Garciaparra, acquired from the Boston Red Sox in a four-team trade July 31, took batting practice Monday. Baker said there has been no decision about whether to put Garciaparra on the disabled list.
“We just have to wait this thing out and see,” Baker said. “There’s going to come a point where we have to make a decision and hopefully it’s a good decision, not a bad one.”
Garciaparra said that option hasn’t been talked about.
“None of that has been discussed right now, we haven’t even talked about that,” he said.
The Cubs have won five of their last six to pull into a tie with the San Francisco Giants for the NL wild-card lead.
For the second time this season, city officials gave the Cubs a game-day go-ahead to play at Wrigley after the stadium passed another round of inspections of repair work done on its crumbling upper deck.
On July 30, officials allowed the Cubs to play after they installed safety nets to ensure fans would not be hit by any of the debris that has fallen three times this season at the 90-year-old ballpark.
The Brewers have lost a season-high six straight to fall 13 games below .500 for the first time this season.
