Lyles was recalled Monday.
Lyles last pitched for the Rockies on May 23 when he gave up four earned runs in 2.1 innings of work, bringing his ERA to 8.55 and WHIP to 2.05 on the season and leading him to be optioned to Triple-A. Lyles will likely serve as a long reliever, a role that is needed due to Tyler Chatwood and Chris Rusin both being lost to the 15-day DL.
