The Arizona Diamondbacks right-hander experienced success against the Giants earlier this season.
De La Rosa will make the start against the San Francisco Giants on Friday night in Chase Field. A corresponding move will be made prior to first pitch.
At this point, De La Rosa’s work load is uncertain. Earlier this week and during the final leg of a road trip in Los Angeles, manager Chip Hale indicated De La Rosa may throw as much as 70 pitches. His health will determine the length.

De La Rosa was placed on the 15-day D.L. with elbow inflammation on May 27. At the time, De La Rosa’s projection on the disabled list was the “X” factor. During his rehab, the native of the Dominican Republic suffered a setback, and on August 12, De La Rosa felt tightness in his right forearm.
Dr. James Andrews performed an MRI and determined that De La Rosa did not need surgery. Instead, Andrews recommended a rehab program, and asked De La Rosa to abort his change-up during his recovery.
After throwing a side session on August 23, De La Rosa began a rehab assignment with Advanced-A Visalia. Making his second start with the Rawhide, De La Rosa threw 30 pitches in two innings on this past Monday. De La Rosa gave up two hits and struck out four in the Rawhide’s 9-7 victory over the San Jose Giants.
Before placement on the DL, De La Rosa complied a 4-5 record with a 4.15 ERA (22 ER/47.2 IP) in 11 games (eight starts).
Right-hander Braden Shipley was scheduled to start Friday night against the Giants. Shipley’s next start is unknown. The rest of the probables for the Giants’ series do not change. Archie Bradley starts on Saturday, and Zack Greinke goes in the Sunday afternoon finale.
