HOUSTON -- Injured Reds starter Aaron Harang's latest test of his strained right forearm went well on Monday.
In his first mound work since pitching against the Cubs on July 8, Harang threw 31 pitches in a side bullpen session at Minute Maid Park. The right-hander stuck to fastballs and changeups and avoided breaking pitches.
"[It went] really good," Harang said. "So good that I got into rapid-fire mode and had to stop myself."
Harang, who is on the 15-day disabled list, is next scheduled to face hitters in a live batting practice session on Wednesday.
A Minor League rehab assignment is a possibility for Harang, who was shut down from throwing for two weeks so his arm could improve. He began long tossing on Wednesday.
"I've got to build my arm strength up and get my pitch count back up there," Harang said. "It's not 100 percent what we're doing. They just want to go day-to-day. We don't want to get too far ahead of ourselves. We'll aim for live BP on Wednesday and see where we go from there."
Reds infielder/outfielder Jerry Hairston Jr. (strained right hamstring) is headed to Triple-A Louisville to begin a rehab assignment on Tuesday, the day he's eligible to come off the DL. Hairston is expected to play a few games before he is activated.
"He'll have to play and see what he can do," Reds manager Dusty Baker said. "He'll play some short and play some third. Right now we're trying to decide, between him and us, how many days are necessary."
