Righthander Asher Wojciechowski has returned to Houston for a platelet-rich-plasma injection as he continues recovery from a strained right lat muscle.

“I’m here just to get a PRP injection in my lat to help the healing process,” Wojciechowski said. “It’s supposed to help with the recovery time.”

Wojciechowski said he was slated to return to Florida on Thursday evening.

Wojciechowski went for a second MRI on the lat on Monday, after first suffering the injury Feb. 1 while throwing a bullpen.

… Japhet Amador’s imminent arrival in Astros camp after it appeared he could leave the organization was positive news to Porter, who has an open first-base competition. Amador did not report to Astros camp on time because of his ill, pregnant wife, his agent said.

“That’s definitely a good thing,” Porter said. “Obviously, he had to tend to some family issues. We’re excited that he’s going to be able to come here and compete for the first-base job, and I look forward to getting him here and talking to him just making sure everything is OK on the home front.”

Amador’s competitors for the job include Marc Krauss, Jesus Guzman, Brett Wallace and Jonathan Singleton.
