The Nationals will face old buddy John Lannan again tonight. But, first baseman Adam LaRoche will take a seat against the lefty. Chad Tracy will play first base tonight. Without Tyler Moore around, the Nats lack a right-handed complement to LaRoche at first base. Lannan returns to D.C. today for the first time since being non-tendered by the Nats this winter. Update: Change of plans. LaRoche is now in the Nats lineup, hitting sixth. For the Nationals: CF Denard Span 3B Ryan Zimmerman LF Bryce Harper RF Jayson Werth SS Ian Desmond 1B Adam LaRoche C Wilson Ramos 2B Anthony Rendon RHP Dan Haren
