Diamondbacks activate RHP Justin Martinez from the 60-day injured list.
Martinez, who was emerging as Arizona’s closer when he was hurt last year, returns 14 months after Tommy John surgery. He pitched four hitless innings with six strikeouts and one walk in four rehab appearances. He’s yet to pitch on back-to-back days, and the D-backs will want to be careful with him. Still, he could quickly become a candidate for save chances.
