Reliever Jesse Crain, who figured to be one of the Chicago White Sox's primary trade candidates this month, and first baseman Paul Konerko were placed on the 15-day disabled list Wednesday. Crain (shoulder strain) was placed on the DL retroactive to June 30, and manager Robin Ventura said he could be ready to return after the July 15-18 All-Star break. Crain's condition flared up while he was warming up in the seventh inning of Tuesday's game but sat down after the White Sox extended their lead with three runs en route to a 5-2 win over the Orioles. Crain is 2-3 with a 0.74 ERA and 46 strikeouts in 38 games. Konerko, who has been battling a lower-back strain, went 0-for-4 Tuesday with two strikeouts. He is hitting .249 with seven homers and 37 RBI in 67 games, and also is expected to return after the break. The Sox recalled third baseman Brent Morel and purchased the contract of left-hander David Purcey from Triple-A Charlotte.
