Locke was optioned to Triple-A Indianapolis on Saturday, Rob Biertempfel of the Pittsburgh Tribune-Review reports. This is nothing more than a paper move, as Locke is expected to return to make his next scheduled start Tuesday in St. Louis. Locke has given up 10 homers in 49 innings since the All-Star break, but he held the Cardinals to one run on six hits over 7.1 innings his last time out. Infielder Brent Morel was recalled in the corresponding move.
