Joe Mauer returned to the Twins on Saturday, but he wasn't in the lineup at catcher. Mauer played first base and batted third for the second game of an interleague series against the Reds. He was out of the lineup for the last four games because of a bruised right thigh. "So it serves two purposes," Ron Gardenhire said, saying that Justin Morneau needs rest. "He's ready to catch. If I wanted him to catch today, he'd catch today. But Morney needs a break. I'm worried that there's rivers around here and that he might jump into the water and try to swim 'em because he's a little frustrated. I'd like him to walk across the bridges now, so I'm going to give him a break."
