• Cubs pitcher Neil Ramirez began his rehab assignment on Wednesday, pitching for the Rookie League team in Mesa, Ariz. Ramirez faced five batters and gave up two runs (one earned) on one hit and one walk in two-thirds of an inning, while striking out one.
He was placed on the disabled list July 26 with right triceps soreness, and there is no timetable for his return.
• Felix Doubront, on the disabled list with a left calf strain, threw 88 pitches in a side session on Wednesday and could begin a rehab assignment next week. The Cubs acquired Doubront from the Red Sox for a player to be named on July 30. Doubront was in Denver with the Cubs, and will accompany them to Chicago.
