Grimm, La Stella recalled; Anderson to DL

CHICAGO -- The Cubs shuffled the roster Sunday, recalling right-handed reliever Justin Grimm and infielder Tommy La Stella from Triple-A Iowa, placing starting pitcher Brett Anderson on the 10-day disabled list and optioning lefty reliever Rob Zastryzny to Iowa.
Anderson injured his lower back fielding a bunt single by Aaron Hicks -- the second batter of the game -- on Saturday night. He missed nearly all of last season after needing surgery for a herniated disc in March.
Grimm began the season with the Cubs but was optioned on Friday because the club needed a fresh arm in the bullpen heading into the Yankees series.
La Stella began the season with the Cubs before being optioned on April 22. With Iowa, La Stella hit .267 with a double, a home run and two RBIs in 12 games. He found out about the callup after homering in Saturday's game.
"It's a little different approach, being down there [in the Minor Leagues] and getting four or five [at-bats] every night," La Stella said. "You take a little different approach than when you get the one [at-bat] in the seventh and you don't want to miss it. You want to establish yourself and get in the game flow."
Zastryzny was promoted on Saturday from Iowa, and gave up three runs in a career-high four innings. He has a 6.88 ERA in seven relief appearances with Iowa this season.
