CHICAGO — The Chicago White Sox are hoping outfielder Dayan Viciedo will be able to return relatively quickly after he strained his left oblique.

Viciedo was placed on the 15-day disabled list on Saturday.

“We’re hoping it’s two weeks,” White Sox manager Robin Ventura said. “Sometimes those can be longer. He doesn’t necessarily have a patient or deliberate swing. It’s a violent swing. That’s the other thing. You let him go back out there and swing and it will probably be worse. You see people down for a long time.”

Viciedo was injured while batting in the eighth inning at Toronto on Thursday, and the roster move was made retroactive to Friday. He is batting .229 (11-for-48) with two homers and five RBIs in 13 games.

“It’s very disappointing, but those are some of the things you can’t control,” Viciedo said through a translator. “I’m going to work to get better so I can help the team as soon as possible.”

White Sox General Manager Rick Hahn said Viciedo will refrain from baseball activities for about a week, then may begin a rehabilitation assignment.

Astros

Martinez on DL with knee sprain: In Houston, the Astros placed outfielder J.D. Martinez on the 15-day disabled list with a sprained right knee and activated outfielder Fernando Martinez from the disabled list to take his spot on the roster.

J.D. Martinez was injured on a check swing in the fourth inning of Friday night’s game. He is hitting .244 with two homers and seven RBIs this season.

Fernando Martinez has been on the disabled list since March 27 with a strained left oblique. He played five rehabilitation games with Triple-A Oklahoma City. Fernando Martinez hit six home runs with 14 RBIs in 41 games for the Astros last season.

Braves

DeWitt goes on 15-day DL: In Atlanta, the Braves placed infielder Blake DeWitt on the 15-day disabled list and recalled right-hander David Carpenter from Triple-A Gwinnett.

DeWitt has lower back soreness, an injury that limited him to 48 games last season between the major leagues and minor leagues in the Chicago Cubs’ organization. He is 1-for-3 in four games for Atlanta after beginning the season with Gwinnett.

Carpenter was in uniform for Saturday night’s game against the Pittsburgh Pirates after going 1-2 with a 4.76 ERA in four relief appearances with Gwinnett.

In 2011-12, Carpenter pitched in 67 games with Houston and Toronto. He was converted from a catcher to a pitcher in 2009 while in St. Louis’ farm system.
