With Greene (2-4, 3.93 ERA) on the injured list, all three of the Reds’ top starters from last season are on the injured list at the same time.
Graham Ashcraft (3-5, 6.78) went on the 15-day injured list on June 9 with a right calf contusion. He’s eligible to return Saturday.
Nick Lodolo (2-1, 6.29) has been on the injured list since May 14 with a stress reaction in his left tibia. He’s not expected to return until August.
Greene last pitched Saturday in a 10-3 victory against the Houston Astros. He allowed two earned runs on five hits in six innings. His next scheduled start was Friday in the opener of a three-game series against the Atlanta Braves in Cincinnati.
Brandon Williamson (1-0, 5.40), Ben Lively (4-4, 4.07) and Andrew Abbott (3-0, 0.00) will start the three games against the Rockies.
