Cubs third baseman Aramis Ramirez said Sunday that manager Lou Piniella is not to blame for the team's struggles this season. "Lou's good, he knows what he's doing," Ramirez said. "He's been a good manager for [many] years, and he played the game, too. "If anybody knows how to handle the club, it's Lou. As players, we haven't gotten it done." Ramirez, who was rehabbing his injured left thumb, is one of several Cubs who have struggled this season.
