Lorenzen threw 40 pitches in his third bullpen session on Friday without issue. He has been out since mid-March with a right teres major muscle strain near his shoulder. He is scheduled to throw live batting practice on Monday.
DeSclafani tossed 29 pitches over two innings in an extended spring training game on Friday and is scheduled to throw a side on Sunday. It was DeSclafani's first game action since sustaining a strained left oblique.
It's the third straight year that DeSclafani has gotten hurt during Spring Training. He missed the entire 2017 season with a right elbow sprain. DeSclafani isn't eligible to be reinstated until May 28.
Lorenzen also remains on track to return toward the end of May, but he'll need to throw simulated games and likely go out on a Minor League rehab assignment to stretch him out before he's activated.
"They're both doing very well," said Riggleman. "They're both on schedule to join us, whenever that is."
Swelling Sal For the second straight start, Reds right-hander Sal Romano used his pitching hand to field a ground ball on Friday night. A day later, he was paying the price.
"Yesterday, for sure," Romano said, when asked which barehanded play hurt worse.
Romano had some swelling in his right hand and received treatment on Saturday.
In the third inning of the Reds' 4-1 win, Romano made a barehanded play on a hard grounder from Marlins pitcher Wei-Yin Chen, then calmly threw to Joey Votto for the out.
Romano said following Friday's game that he will refrain from doing that in the future.
The Red Knight? Matt Harvey's sudden availability will likely spark interest among several clubs, so will the Reds take a flyer? Riggleman said that decision will occur above his pay grade, but he's aware of the hubbub surrounding the former Mets ace.
"He's a guy that is going to get a lot of attention around the league," Riggleman said. "I think a lot of people are going to have to make a decision: Do we want to add him to our club? What do we have to give up to get him?"
The Mets designated Harvey for assignment on Saturday after he refused going to the Minor Leagues. The Mets have seven days to trade Harvey or release him.
Harvey, 29, went 25-18 with a 2.53 ERA through 2015. He's 9-19 with a 5.93 ERA since then.
"I've been watching on TV a lot of talk about that," Riggleman said. "We haven't had any discussions about that. I'm sure [assistant general manager] Nick Krall and [general manager] Dick Williams, his staff and [executive advisor] Walt [Jocketty] are aware of it and considering whether it's something we would engage in, but I don't know."
