A familiar cast of characters helped the Washington Nationals complete a lopsided, season-opening three-game sweep of the payroll-slashing, talent-trading Miami Marlins. Now should come more of a test: a visit to the reigning NL Central champion Cincinnati Reds starting Friday. In Washington's 6-1 victory over Miami in the finale Thursday -- the combined series score was 11-1 -- Jayson Werth tacked on a three-run homer, Ryan Zimmerman's three hits included a two-run double, Bryce Harper had two more hits, and right-hander Jordan Zimmermann went six innings.
