The long relief role was expected to be filled by Rule 5 pick Matt Bowman, until Bowman pitched his way into more high-leverage opportunities with a strong season start. That has left Lyons, one of two lefties in the Cardinals' bullpen, often biding his time in case an extended relief opportunity arises.
"We didn't know if we were going to have the guys in the back end that were going to be able to get left-handers out," manager Mike Matheny said of Lyons' changing role. "I think it can still evolve, too, to where he can come in and face the tough lefties. The other part of that is we have an opportunity to use him in the long situations to where he's good for 50, 60 pitches. That's a nice weapon for us to have."
Nine of Lyons' 20 appearances this season have been more than one inning in length. The role, however, also has produced irregular work. He's gone at least six days in between outings four different times, and half of Lyons' appearances have come on at least four days of rest.
"I think I've done it enough now over the last couple years where I have stretches without throwing that I kind of have an idea what I need to do," Lyons said. "Sometimes as we go along through those stretches, I throw harder [during pregame work]. I throw more. I do a couple things like that just to stay ready."
• Catcher Brayan Pena will wrap up his Minor League rehab assignment on Sunday as it hits the maximum 20 days in length. The Cardinals will have to make a determination about where to move him at that time. The expectation is that Pena will rejoin the big-league team on Monday, likely taking the roster spot that has been filled by Eric Fryer since the start of the season.
• Right-hander Corey Baker shined in his Triple-A debut on Saturday as he allowed four hits and struck out six over 6 2/3 scoreless innings. He earned the win, which was helped by an RBI single by Randal Grichuk. Baker was a 49th-round pick by the Cardinals in the 2011 MLB Draft.
