Gray (foot) will make one more rehab appearance Saturday before returning to the Rockies next week, Nick Groke of The Denver Post reports.
This will be the third rehab start for the right-hander, who has struck out 12 and allowed five runs (one earned) over eight innings in his first two outings. Gray only started three games this season before suffering the stress fracture in his left foot, racking up an ERA of 4.38 in 12.1 innings posting an ERA of 4.61 in 29 starts in 2016.
