Before that happens, Iglesias is scheduled on Friday to throw "live batting practice" against Reds hitters for the second time this week. He threw 20 pitches to hitters on Tuesday.
Iglesias started camp slightly behind other pitchers because he underwent a special shoulder flexibility program during the offseason to stave off the fatigue that cut short his 2015 season in mid-September.
More notes from Thursday
• In the bottom of the fifth inning during the Reds' 5-4 win over the Rockies, right fielder Jesse Winker and center fielder Jake Cave collided on a fly ball hit by Nolan Arenado. Winker, the Reds' No. 1 prospect according to MLBPipeline.com, was lifted after the inning as a precaution with a contusion on his leg. It was not believed to be serious, according to Price.
• Shortstop Zack Cozart, who had reconstructive right knee surgery in June, will make his spring debut when he starts Friday's split-squad game vs. the A's in Goodyear.
• Center fielder Billy Hamilton, who has had a setback with his surgically repaired right shoulder at the beginning of the month, was scheduled to play catch on Thursday. Hamilton took swings off the tee on Wednesday.
• Outfielder Kyle Waldrop has been limited to two at-bats this spring and hasn't played lately because of a sore groin. Waldrop was scheduled to try running on Thursday.
"There's no lateral cutting or anything that would exacerbate the problem," Price said. "It's kind of baby steps at this point."
• During Wednesday's 11-5 Reds loss to the Rangers, outfield candidate Yorman Rodriguez showed off his arm strength in the first inning. As Shin-Soo Choo tried to go from first to third base on Ian Desmond's lined single to right field, Rodriguez fired a strike to third baseman Eric Jagielo and easily threw out the runner.
"He's worked hard on his throwing," Price said. "I know just recently he changed the way he's gripping the ball. He had some concerns his ball was cutting and he was throwing a lot of balls down into the ground."
