That does not mean he is looking to leave.
"I want to stay," Lopez said. "I'm happy here. I like the organization, I like how they work."
The D-backs entered play Sunday 11 games below the .500 mark and in last place in the NL West. It's certainly not what Lopez thought he was getting into when he inked a one-year deal in December for $3.5 million.
"When I signed here I thought we were going to be a winning team and I still think we have a team that can compete," he said. "It's just going rough for us right now. We've got a lot of people struggling, playing out of position. I still believe that this team can do it. Maybe I'm stupid for saying that, but spending time with these guys and knowing how talented they are, I believe it."
Lopez came into Sunday's game hitting .299 with a .413 on-base percentage. He said his attitude is good because he believes there are better times ahead for the team.
"That's why I come to the ballpark every day and try to motivate them," he said. "I know they're still young, that's why I always am behind them saying let's go to the cage and am always talking to them.
"It's just a matter of time here until everyone figures it out and clicks together."
