VIERA, Fla. (AP) - Jarred Cosart pitched five perfect innings Wednesday night, leading the Houston Astros to a 2-0 victory over the Washington Nationals.

After the game, Nationals manager Matt Williams said Stephen Strasburg would make the opening-day start at the New York Mets on March 31.

Cosart struck out nine, including six in a row and seven of eight. The right-hander had come into the game with a 7.17 ERA through his previous three starts.

“That’s the best I’ve seen him as far as the sharpness of his off-speed stuff,” Astros catcher Jason Castro said. “That’s the best I’ve ever seen his breaking ball. He’s been working a lot on that. It’s come a long way even since the beginning of spring. . It’s really good to see. It was a fun game to catch for sure.”

After going through the Nationals lineup the first time, Cosart started Washington’s top three hitters - Denard Span, Ian Desmond and Ryan Zimmerman - with a breaking ball the time through the order.

Cosart said he has been told one of the biggest adjustments he needs to make to stay in the big leagues is to be able to throw his breaking ball for a strike in any count.

“I threw it 0-0. I threw it 0-1, I threw it 2-1(and) 2-0,” Cosart said, “just to be able to have the hitters have something else in their mind. It paid dividends today.”

Anthony Rendon became Washington’s first base runner when he singled off Houston’s Raul Valdes with one out in the sixth.

Washington starter Taylor Jordan, who is competing for the team’s fifth starting spot, allowed three hits and one run over five innings. He struck out three.

The right-hander was more aggressive than in his previous start and worked on his fastball command.

“My control wasn’t like I had wanted it, but I had some good movement on my sinker today and my changeup was working here and there,” Jordan said.

The Nationals were held to just five hits. Jesus Guzman hit a solo home run for the Astros.

STARTING TIME

Nationals: Jordan is competing with Tanner Roark and Chris Young for Washington’s final starting spot, but said he is trying not to think about it.

Astros: With his off-speed pitches working so well, Cosart was able to freeze a number of Nationals hitters with an inside fastball. Four of his nine strikeouts came on called third strikes.
