Ryan Zimmerman saved a run or two with a quick stab to stop a double down the left-field line in the first inning, charged a two-hopper barehanded to throw out the swift Shane Victorino in the fifth, then made a tough catch look routine when pinch hitter Greg Dobbs hit a foul pop-up in the seventh.

And, by the way, he was on base every time the Washington Nationals scored.

With the help of his third baseman’s flawless defense, Tim Redding threw 6 1-3 scoreless innings and the Nationals opened a seven-game homestand Monday night with a 4-0 victory over the Philadelphia Phillies.
