"Aaron Harang's comeback 2011 season has been put on hold. The Patrick Henry High and SDSU product will be placed on the disabled list today with what manager Bud Black called a "stress reaction" to his right foot.

Double-A San Antonio pitcher Anthony Bass will make his major league debut when he's promoted to make today's start at the Colorado Rockies. Black also said he anticipates center fielder Cameron Maybin, on the DL retroactive to May 28 with right knee inflammation, will be activated in Colorado.

After posting a combined 18-38 record the previous three seasons, Harang was off to a 7-2 start, his most wins in a season since 2007.

"It's very frustrating," said Harang, adding he tried to talk the team into skipping him for one start rather than putting him on the disabled list."
