Jesse Crain, Paul Konerko on DL

CHICAGO -- The Chicago White Sox placed Jesse Crain and Paul Konerko on the disabled list prior to Wednesday night's game against the Baltimore Orioles, potentially hurting their chances of trading either player.

Crain, who was expected to be one of the White Sox's more popular assets as the non-waiver trade deadline approaches, was put on the DL with a right shoulder strain. The move is retroactive to June 30, the last time he appeared in a game.

He had an MRI on Wednesday, exactly a year to the day that he had an MRI for the exact same injury in 2012. He had already been on the DL at that point last year and spent just short of a full month getting back to full strength.

"It didn't feel good playing catch before the game [Tuesday]," Crain said. "I just think it started happening from the work I've been doing and throwing a lot and I think it's finally started getting tired. And it's sort of like last year. When it gets tired, I think that's what my arm does, it gets strained."

Crain has 38 appearances this season, second on the team to Matt Lindstrom's 39. He has been one of the best setup men in baseball with a 0.74 ERA that leads all American League relievers. His franchise-record 29-game scoreless streak ended June 23, and his 31-game streak of not allowing an earned run ended Saturday.

Konerko, who would have to waive his 10-5 rights to OK a trade, was put on the DL with a lower back strain. The injury flared up after the June 23 game at Kansas City, forcing Konerko to miss the first five games of the current homestand. He had a series of six pain-killing injections last week and returned to action Tuesday only to have a setback.

"[Tuesday] night by the end of the game, Paulie just didn't feel right and he got examined and it kept getting worse until he felt like he took a few days backwards as far as the way he was feeling," manager Robin Ventura said. "It's something he's felt like he's done before and it passed, and the best way to do it is get some rest."

Although it has been reported that the White Sox are willing to talk trades for anybody except Konerko and Chris Sale, Konerko didn't exactly say this weekend that he was closed off to being involved in a deal. He simply called trade talk something that's "off in the distance."

Infielder Brent Morel was recalled from Triple-A Charlotte, and left-hander David Purcey's contract was purchased from Charlotte.

Morel was batting .283 at Triple-A Charlotte with 20 doubles, five home runs and 40 RBIs in 68 games. He went 2-for-9 in three games with the White Sox this past weekend.

Purcey had a 3.03 ERA with 43 strikeouts in 26 appearances (38 2/3 innings) at Charlotte. He has a career 5.38 ERA over 180 2/3 major-league innings with the Blue Jays, A's and Tigers. He had been a starter through the 2009 season.
