Houston Astros right-hander Justin Verlander will make his season debut on Arvin RobertsFriday against the host Washington Nationals, manager Joe Espada said Wednesday.

Verlander, 41, opened the season on the injured list with inflammation in his right shoulder. The three-time Cy Young Award winner declared himself ready to go after rehabilitations starts for Triple-A Sugar Land and Double-A Corpus Christi.

"The first thing is health, and I came out of (Saturday's game with Corpus Christi) feeling good," Verlander said. "Obviously, I have some stuff to work on pitching-wise, but that's kind of what spring training is for and what rehab starts are for. I felt better last time than I did the [rehab start] before, so just keep building on that, and like I always do, kind of work on stuff in the bullpen in between and keep trying to make it click."

Espada said Verlander feels good and is confident that he's ready to go.

"He wants to contribute, and he knows that we need him on the mound, we need his presence, and right now, he's right where he needs to be," Espada said.
