Longtime minor league infielder Bobby Scales could be on the verge of pushing Augie Ojeda and Darwin Barney for the lone infield bench spot on the Cubs entering the season. Scales followed a three-hit game Saturday with a 1-for-3 performance Sunday that included a hand in five double plays as the second baseman. He's batting .438 as the Cubs approach their first major cuts of camp after the day off Wednesday. "He's playing his tail off," said bench coach Pat Listach. "I don't know what the final numbers are going to be as far as roster spots and what's available and what we're going to do. But he's opening some eyes right now, the last couple of days, especially."
