The Tampa Bay Rays have lost five of their past seven games, and they hope to turn things around on Saturday when they take on the Minnesota Twins in the second game of a three-game weekend set. Taylor Walls is back at shortstop for the Rays, a day after Ha-Seong Kim came off the injured list and played for the first time on Friday. “We’ll see,” Rays manager Kevin Cash said Saturday when asked when Kim might be ready to play. Taj Bradley has been up and down the past month or so, and he needs a big outing on Saturday.
