HOUSTON — The Chicago White Sox have been hit hard with outfield injuries this season.

Adam Eaton became the latest to be sidelined when the Sox on Thursday placed the starting right fielder on the 10-day injured list with a strained right hamstring.

The move is retroactive to Tuesday.

“He’s dealt with it, he’s gone out there like a good competitor and it takes away from his game,” Sox manager Tony La Russa said before Thursday’s game against the Houston Astros at Minute Maid Park. “The decision was made, just get him well.”

Eaton is slashing .195/.296/.345 with seven doubles, two triples, five home runs, 27 RBIs and 30 runs in 54 games.

The Sox are already missing starting left fielder Eloy Jiménez and center fielder Luis Robert.

Jiménez has been out since spring training with a ruptured left pectoral tendon. He was medically cleared Monday to resume baseball activities at the team facility in Glendale, Arizona.

Robert went on the 60-day IL in early May after he suffered a complete tear of his right hip flexor.

Billy Hamilton is also on the injured list with a strained right oblique.

Jake Lamb started in right field Wednesday against the Tampa Bay Rays, while Brian Goodwin got the nod Tuesday and Thursday.

Goodwin reached base in four of his first five games with the Sox since being called up from Triple-A Charlotte on May 10. He had five RBIs in his debut Saturday against the Tigers in Detroit.

“He’s been very impressive,” La Russa said of Goodwin.Lamb hit safely in 10 of his last 14 games. He’s 12-for-44 with two doubles, three home runs and seven RBIs during the stretch.
