• Johnson expressed no concern about veteran right-hander Dan Haren, who dealt with back and hip problems last year and went 0-4 with a 6.39 ERA in six Grapefruit League starts. Haren allowed 14 earned runs and seven homers across 16 1/3 innings in his final three outings.
"I never put anything on what happens in spring," Johnson said. "I look at where I think their arm strength is, how they handled and came back from each [outing], how they progressed. I liked how he was throwing the ball at the end of spring. I think he liked how he was throwing the ball."
• Closer Rafael Soriano, one of the Nationals' big offseason acquisitions, pitched in only seven Grapefruit League games, posting an 8.10 ERA in 6 2/3 innings. But Johnson believes the righty is ready for Opening Day, a year after saving 42 games for the Yankees.
"I wish he had another one or two appearances, but he knows what he's doing," Johnson said. "He'll be ready."
• Johnson called third baseman Ryan Zimmerman's good health "probably the most gratifying thing this spring." Zimmerman dealt with right shoulder problems that restricted his throwing last year, but offseason surgery cleaned up those issues.
• Reliever Drew Storen received plenty of cheers when he entered Friday's game in the top of the ninth inning and produced a scoreless frame. It was his first game at Nationals Park since he was charged with a blown save and the loss in Game 5 of last year's National League Division Series against the Cardinals.
"It's like riding an old bike, to get back and get to pitch here at Nationals Park," Storen said. "It was fun. I'm really glad, actually, we got the exhibition in. We get to come up, and it's not the same pitching in the stadiums before that, so to get back and pitch in front of the home crowd and in your home stadium, it's great."
