Kris Bryant, the Rockies' oft-injured first baseman and right fielder, is back on the 10-day injured list with a low back strain, the club announced Wednesday. Bryant's stint on the injured list is retroactive to April 14. To replace Bryant on the 26-man roster, the Rockies recalled outfielder Sean Bouchard from Triple-A Albuquerque. Bryant, 32, is improving from the injury he sustained when making a catch and crashing into the right-field wall on Saturday at Rogers Center in Toronto, but the club decided he needed more time to get healthy.
