CHICAGO -- The Dodgers activated Rich Hill off the 10-day disabled list to start the nightcap of Tuesday's doubleheader against the Cubs, recalled right-hander Brock Stewart as the allowed 26th player and optioned infielder Breyvic Valera to Triple-A Oklahoma City.
Hill turned in a scoreless start, working six innings and allowing three hits, two walks and recording six strikeouts. He tossed 90 pitches (65 strikes) and left the game with a one-run lead before the Cubs rallied for a 2-1 walk-off victory in the 10th inning. 
The 38-year-old lefty has spent a pair of three-week stints on the disabled list with blister issues on the middle finger of his left hand. His most recent start was May 19 in Washington, and it lasted only two pitches.

Hill made a four-inning rehab start for Class A Advanced Rancho Cucamonga on Thursday, striking out 10. He said he was excited about a mechanical adjustment he had made in his delivery.
Stewart was recalled for the sixth time this season.
