The encouraging start means that the Rockies will be examining the possibility of Lyles starting a game during the team's next homestand, which begins Tuesday against the Cubs.
"Jordan's an option," Weiss said. "We have the off-day when we go back home and there's a chance that he could be slotted in on that homestand. We're still trying to line up some things because we do have the off-day. Jordan could certainly be one of those pieces."
Lyles has been out since June 4.
