Cards waiting to decide on next step for Lyons

ST. LOUIS -- Tyler Lyons, two days after throwing 54 pitches in a Triple-A rehab appearance, threw a bullpen session at Busch Stadium on Monday afternoon. However, the Cardinals will wait another few days, general manager John Mozeliak said, before determining what the next step is for Lyons, who is recovering from a left shoulder strain.

The Cardinals have the option of continuing Lyons' rehab assignment by sending him back to a Minor League affiliate to make another appearance later this week. The club could otherwise remove him from the disabled list and assign him to the Cardinals or Triple-A Memphis.

Lyons has so far made two rehab starts. He allowed one run on four hits and two walks while striking out three in a 2 2/3-inning outing on Saturday.

"I feel like my stuff's there now and I feel like I'm strong," Lyons said on Monday, upon returning to St. Louis. "Now it's just about making it last for an extended period of time. I've done it for short bursts in two innings and almost three innings. It's about lengthening it out now if you're going to be a starter."

Kevin Siegrist (left forearm strain) is still scheduled to begin a rehab assignment later this week, though the Cardinals will first have him throw once more in St. Louis on Wednesday. Where Siegrist will be sent has not yet been announced.
