SAN DIEGO -- Astros closer Brandon Lyon remains on course to begin a rehab stint Sunday at Triple-A Oklahoma City after throwing a simulated game Thursday at PETCO Park. Lyon has been on the disabled list since May 5 with right biceps tendinitis and a partial tear of his rotator cuff.
He threw about 20 pitches to hitters Thursday in what he described as a step in the right direction.
"I thought it went pretty good," he said. "It was my first time out there and seeing hitters. I felt better than I expected to."
Lyon threw without any hesitation and wasn't thinking about getting hitters out.
"I was trying to work on some things, get an idea of seeing a hitter up there," he said. "I had [Angel] Sanchez batting left-handed, so I didn't take it too seriously. I was just trying to work on throwing to a catcher and working on location, knowing someone isn't try to kill it. I felt good, and it was a step in the right direction."
Lyon, who blew four saves and allowed nine earned runs in 11 1/3 innings, is scheduled to pitch Sunday and Tuesday for Oklahoma City.
"I had a lot more strength in my arm and I'm bouncing back quicker day to day," he said.
