The Rockies acquired infielder Mark Ellis on Thursday, a trade that could be a precursor to more transactions. With Colorado under .500 at the midway point of the season, more moves are expected. A starting pitcher is a possibility, what with Jorge De La Rosa gone for the season after elbow surgery. "We're going to continue to look for pitching and another bat," general manager Dan O'Dowd said. "We're just going to try to take one thing at a time as they get presented to us."
