Lyles holds a 2.63 ERA and 1.17 WHIP in 13.2 innings since he was promoted to the majors on June 20.
After a putrid start to the season in which the he allowed at least five runs in four of his five appearances, Lyles has completely turned things around. His strikeout numbers are still lackluster at best since the promotion (5.3 K/9), but his stellar 1.3 BB/9 and 0.7 HR/9 are allowing him to hold his own in the big leagues. The right-hander's role may be in question in the coming days, even with his recent success. Chris Rusin (shoulder) is expected to come off the disabled list in the next week, which could put Lyles' job as the long reliever in jeopardy. How the Rockies plan to handle this situation will likely become more clear as Rusin's activation nears, but in the meantime, Lyles will look to continue pitching like he has over the past month, a time in which he's lowered his ERA from 8.55 to 6.15.
