Leonys Martin is not in Thursday's lineup against the Red Sox.
Delino DeShields will start in center field and bat leadoff against Red Sox rookie left-hander Eduardo Rodriguez. Chances are Martin will be back in there Friday with right-handed knuckleballer Steven Wright on the hill.
White Sox released 1B Dan Black.
Black was released from his contract to pursue an opportunity with a team in the Koreaa Baseball Organization. The 27-year-old was batting .324/.457/.568 with six home runs and 24 RBI through 34 games this season at Triple-A Charlotte.
Alexei Ramirez is out of the starting lineup for the second game of Thursday's doubleheader against the Orioles.
Gordon Beckham will start at shortstop and bat fifth. This will be his first start at shortstop this season and just the third of his career.
Manny Machado will bat leadoff and play third base in the second game of Thursday's doubleheader against the Orioles.
Machado was ejected from the first game of the doubleheader after slamming his bat when he was called out on strikes, but he's right back in there for the nightcap. David Lough will start in left field while Steve Clevenger is behind the plate.
Mariners prospect 3B/1B D.J. Peterson went 2-for-4 with a home run and four RBI on Wednesday for Double-A Jackson.
The home run was just the second of the year for Peterson, who slugged 31 in 2014 between High-A High Desert and Jackson. Even more concerning is the fact that the 23-year-old is batting just .213/.282/.305 with a 44 strikeouts through 42 games. But while it’s been a slow and disappointing start to the season for the 2013 first-round draft pick, his strong track record as a professional suggests his production will eventually pick up.
White Sox recalled RHP Chris Beck from Triple-A Charlotte.
Beck will be making his major league debut when he starts the second game of Thursday's doubleheader against the Orioles. The 24-year-old had a 3.30 ERA and 33/11 K/BB ratio in 46 1/3 innings through his first eight starts this season in Triple-A.
White Sox optioned RHP Scott Carroll to Triple-A Charlotte.
Chris Beck will replace him on the roster for Game 2 of Thursday's doubleheader against the Orioles. Carroll has posted a 3.12 ERA and 7/7 K/BB ratio over 17 1/3 innings this season in a middle relief role.
Wei-Yin Chen will start Saturday against the Rays.
Chen recently dealt with some undisclosed soreness, but it's apparently not a major concern. The southpaw has a 3.13 ERA and 44/14 K/BB ratio in 54 2/3 innings over his first nine start this season.
