Alex Wood could be headed to the disabled list with left shoulder inflammation.

Wood pitched six innings against the Pittsburgh Pirates on Monday night. He gave up three home runs for the second time in his 134 Major League appearances.

Dave Roberts said Wood is experiencing inflammation in the sternoclavicular joint in the front of his pitching shoulder, an issue that Wood has had in the past. He was placed on the 10-day DL in May with the injury.

"We'll make a decision once the medical staff puts an eye on him," Roberts said. "It's a little concerning considering his history. ... We really have got to be cautious."

Wood is 14-1 with a 2.41 ERA and 127 strikeouts in 123 1/3 innings this season for the Los Angeles Dodgers.
