• Cubs reliever Carlos Marmol, on the disabled list with a strained right hamstring, was scheduled to pitch one inning on Sunday for Triple-A Iowa, his second rehab appearance.

On Friday, Marmol gave up one hit, walked a batter and struck out one in one inning, his first game action since May 11. If all goes well, he could join the Cubs on their next homestand, which starts Monday.

• Ryan Dempster's third annual Casino Night on May 9 raised more than $350,000 for his foundation. About 600 celebrities and guests attended the event, held at Chicago's Palmer House Hilton hotel. A 2012 World Series trip sold for $40,000, and an authentic Babe Ruth and Lou Gehrig autographed baseball sold for $21,000. Proceeds from the baseball will benefit the new Ann & Robert H. Lurie Children's Hospital in Chicago.

• Infielder Blake DeWitt, playing for Triple-A Iowa, was placed on the disabled list with a sprained left wrist which he injured while diving for the ball in the outfield. He has played in four games for the Minor League team since he was designated for assignment by the Cubs. DeWitt was examined by Cubs team doctors in Chicago.

Left-handed pitcher Jeff Beliveau, who had pitched in 16 games in relief for Iowa, was also placed on the DL with a strained shoulder.

The Cubs also have signed free agent infielder Diory Hernandez, 28, who was hitting .159 for Triple-A Oklahoma City and released May 23, and assigned him to Iowa.
