Rodriguez won't be eligible to make that start because he has to stay in the Minors for 10 days, but right-hander Jordan Lyles could be brought back. Lyles made a spot start April 29 in Cincinnati, allowing four hits and three runs in six innings, and was shipped right back to Oklahoma City.
"It's kind of tough now when you look at those two performances to gauge where we're at," Astros manager Brad Mills said. "It's outstanding that both of those guys are progressing, and there's no doubt the way baseball is, we'll probably see them again fairly soon."
Lyles, 21, is 4-0 with a 4.22 ERA in five starts at Oklahoma City, and last pitched on Saturday. He was 2-8 with a 5.36 ERA in 20 games, including 15 starts, for the Astros last year.
