Chicago has been linked to such potential trade targets as starting pitchers David Price, Mat Latos, Mike Leake and Cole Hamels. Hoyer would not comment on specific names.
"Right now, our focus is to find the best fit for us," Hoyer said.
The other issue for the Cubs is the offense, or a lack of it. The team was batting .222 in July entering Friday, hitting just 10 home runs.
"We have a lot of confidence in those guys," Hoyer said. "We've been in a team-wide slump for quite a while, and I'm actually very impressed with our ability to win games even though we're not scoring runs. It says a lot about the pitching staff and the bullpen.
"We're going to have to score more ultimately to get where we want to go, there's no question. Offensively, we could make an addition, but I think the real solutions are within. We need to get our own players to play as they did at the beginning of the season, or how their careers indicate they can play."
