Arizona manager Torey Lovullo said Saturday that Martinez (elbow) will shift his rehab assignment to Triple-A Reno during the upcoming week, MLB.com reports.
Martinez made the first two appearances of his rehab assignment with Single-A Visalia on Tuesday and Friday, striking out three batters over two no-hit innings between the outings. The right-hander will likely continue his rehab assignment for at least one more week, but if he continues to excel during his time at Reno, he could step into a prominent role in the Arizona bullpen upon his return from the 60-day injured list. Arizona is currently taking a committee approach to the closer position after Paul Sewald was removed from the role in late July.
